Measurement amplifier - Import export

The new strain gage amplifier with IO-Link interface enables digitalization of the measurement technology right from the sensor. Its compact design and high degree of protection allow the instrumentation amplifier to be used practically anywhere in the field. Strain gage sensors typically have an output voltage of a few millivolts. In industrial environments, e.g. in the vicinity of electric motors or frequency converters, interference can affect the measurement result when transmitting analog signals. This is reliably avoided using the new strain gage amplifier with IO-Link interface. The analog link between the sensor and instrumentation amplifier is kept as short as possible, the standardized IO-Link communication is fully digital and interference-free. The amplifier is powered directly via the IO-Link interface – a standardized 5-wire cable with M12 socket. Strain gage sensors can be connected via a 4-pin M8 connector.

In practice the requirement often arises to convert the measurement signals of a sensor into a standard signal in the simplest possible manner in the immediate proximity of the sensor. This permits trouble-free, low-loss transmission of measured values over longer distances to an instrument board or plant controls. Ideally suited for this purpose is the in-line measuring amplifier, which is inserted in between in the connection cable by means of plug contacts. Owing to its compact, robust design and low weight, it finds use in almost any application. Even movable locations subject to forces of acceleration, for example manipulators, present no problems. It is intended mainly for use of control cabinets in just about any location and is matched to a specific sensor. The aluminium housing is extremely sturdy and affords the greatest possible protection even in harsh environments.

The amplifier module model 9243 is used wherever measurement signals from strain gauges, potentiometric sensors or DC/DC sensors have to be converted into standard signals. Simply by mounting on conventional DIN-mount rails, it is possible to position the amplifier module on location, in the proximity of the sensor. Especially for rough environments a IP65 version is available. The broad auxiliary power range and the choice between AC or DC permits operation on standard power supplies used in switch gear cabinets. A highly precise reference voltage source is built-in for calibration purposes. A calibrating shunt can also be connected via two separate terminals. This permits deliberate detuning of a strain gauge sensor for calibration or merely to check the measuring chain.

The new 9250/9251 amplifier generation unites all the features that make modern measurement data acquisition actually possible for the first time. Network-compatible, high-precision, user-friendly, smart and versatile: the combined system of amplifier module and Fieldbus controller can be integrated into any existing setup. The Fieldbus controller delivers all signals exactly where they are needed, to be combined, checked and linked. With the available Fieldbus interfaces, you are flexible, perfectly connected and you save time, costs and other resources when linking to and integrating into existing systems. Due to the integrated measuring input, the use of a Fieldbus controller module is sufficient for single-channel applications. For multi-channel applications, the system can be expanded to up to 9 measuring channels. Up to 8 bus-compatible model 9250 instrumentation amplifiers can be cascaded on the model 9251 Fieldbus controller.

The modules of the IMSP series are connected before the interface devices and provide reliable protection against voltage surges. The only 6.2 mm wide DIN rail devices are IP20 rated and can be used in the Ex and non-Ex area. Among other things, modules are available for surge-protected connection of analog signals (e.g. for analog signal isolators and temperature measuring amplifiers) as well as for connecting binary signals from switches or inductive and capacitive sensors.

Inductive displacement sensors using the principle of the differential transformer (LVDT) can be used to measure displacement and, indirectly, magnitudes that can be converted into displacements such as force, pressure, strain, torque, vibration and so forth. Thanks to the high quality of their measurements, their high protection and long service life, these sensors are used in many technologies (industry, research, development, etc.). Applications include measuring, controlling, regulating and monitoring both slow and fast movements between machine parts, measurements of position and positional changes of components and structural foundations, servo regulators, valve and robot controllers, growth measurements and so on. Their design is robust - the internal coils and electronics are potted - as a result of which the sensors can easily withstand shock and vibration.

The pressure transmitter illustrated here measures differences in pressure between the two connections of the measuring element. Pressure differences can be measured with respect to a reference pressure, such as atmosphere, or to the command variable of a regulation system. Equally, however, it is possible to measure pressure differences within systems that have a high static pressure. One practical example of this would be measuring a flow rate by determining the pressure drop occurring across a metering diaphragm. The differential pressure transmitter measures in both directions and can therefore, for instance, be used on double-acting hydraulic cylinders. Its construction permits it to be used with liquid or gaseous media. Venting holes simplify installation. The robust design and the use of stainless steel make it possible to use the pressure transmitter under tough operating conditions.

The new 9250/9251 amplifier generation unites all the features that make modern measurement data acquisition actually possible for the first time. Network-compatible, high-precision, user-friendly, smart and versatile: the combined system of amplifier module and bus controller can be integrated into any existing setup. The amplifier 9250 in conjuction with the fieldbus controller 9251 takes signals exactly to the point where they can be combined, monitored and linked efficiently to other data. The fieldbus interfaces give you flexibility, speed and perfect connections, and save you time, money and other resources when integrating your measurement setup with existing systems. Automatic sensor recognition due to burster TEDS lets you play absolutely safe, protecting you from setting incorrect parameters. The broad supply voltage range permits operation on standard power supplies used in switch gear cabinets.

Situations often occur in practice in which it is necessary to place a measuring amplifier immediately in the neighborhood of the sensor in order to be able to access a standard signal there. In this way, long distances to the evaluating electronics can be covered. This task can ideally be performed by the 9236 in-line measuring amplifier. With its high degree of protection (IP67) its singlechannel version can be integrated into the application even in the tough environment outside the switch gear cabinet. — Automatic production machinery — Laboratory measurements — Integration into customer‘s circuit boards — Field measurements Features: — Operates with up to 4 measuring channels — Voltage output 0 to ± 5 V / 0 to ±10 V — Protected against reverse connection and short-circuit — Also available as circuit board without housing — Simple configuration using DIP switch — High degree of protection up to IP67

The sensor model 8228 with its measuring accuracy of 0.05% F.S. (for the measuring ranges ≤ 1 bar, the measuring accuracy is 0.1% F.S.) ideally suited as a reference sensor. The compact dimensions, the robust housing and the industrial-grade output signal result in a very wide range of applications. All components in contact with media are made of stainless steel. An integrated measuring amplifier converts the measuring signals directly into interference-free voltage signals or current signals that can be transmitted over long distances. With the „gage“ measurement type, the pressure measurement is carried out against the ambient pressure, the sensor has a bore that is protected against ambient influences to compensate for the ambient pressure. With the „Absolute“ measurement type, the applied pressure is measured against an enclosed vacuum; this measurement type is available from the measuring range 0 ... 250 mbar. The electrical connection is made via an M12 x 1 connector.

Based on the SL series, the SLT probes are also characterized by an ultra robust construction and a fully stainless steel housing which makes them suitable for harsh environments. The combination of a hardchrome plated shaft with 6 mm in diameter and precision bearings guarantees highest resistance to lateral forces on the push rod. There are three different functional variants available to meet the demands of most measuring tasks: ■ Spring loaded mechanism: The push rod is fully extended by an internal spring. ■ Pneumatic version 1: The push rod extends by applying pressurized air. An internal spring retracts the push rod after releasing the pressure. ■ Pneumatic version 2: The push rod retracts by applying pressurized air. An internal spring extends the push rod after releasing the pressure. Each sensor requires a carrier frequency measuring amplifier to operate, which evaluates and transforms the sensors signal to a standardised analog output signal of 0...10 V or 4...

This transducer can be used anywhere thanks to its small size. Designed to work without a measuring chamber (uses a flush front diaphragm instead), this transducer is ideal for any measurements where the material to be measured may leave problematic residues. The range of suitable applications is even greater thanks to a choice of screw-on or weld-on adapters. Areas of use: Bottling plants, food industry Mixing facilities for the chemicals industry Pharmaceuticals Cosmetics industry Bioengineering These miniature pressure transducers are made entirely of titanium and therefore have outstanding resistance to corrosion. These convert the pressure-induced deflection of the diaphragm into a change in electrical resistance, which can be amplified, measured and processed by external electronic circuitry.

EGE sensors for fluid mediums with integrated measuring & amplifier are compact devices with extremely robust housing and integrated measuring and amplifier. The current flow state is displayed at the sensor using LEDs. The measurement takes place without mechanically moving parts using a thermal measuring element. Limit values are set directly at the device. These sensors are used wherever a safe, reliable and low-maintenance recording of flows is required. This includes e.g. all automation and chemical industries in the most varied areas, such as cooling circuit monitoring, monitoring the flow rate of process fluids, monitoring metering processes or also for pump protection.

EGE compact devices for the flow monitoring of gaseous media contain measuring and amplifier in a single housing. They are used where a visualisation of the flow rate on site is required. EGE flow sensors for gaseous media feature two pins which contain the thermal measuring elements. The sensors are set up directly at the device. EGE sensors for gaseous media are characterised by a rapid response capability and reliable operation. Based on the principle, there are no moving parts in the air flow monitors and they can, therefore, also be used in aggressive environments. Devices for air conditioning technology have smooth measuring surfaces and need not protrude far into the flow duct.

EGE flow sensors for gaseous media in explosive areas permit the space-saving flow measurement on site and the comfortable setting of the limit value using separate amplifier. The measurement takes place without mechanically moving parts using a thermal measuring element. The current flow state is displayed at the amplifier using LEDs. The devices are used wherever a safe, robust and low-maintenance monitoring of flow values is required. The measuring sensors of the product series ST 400 Ex; STS; STEX have ATEX approval and may, dependent on their design, be used in Gas-Ex areas requiring equipment for EPL Ga or EPL Ga/Gb. In the Dust-Ex area their use is permitted up to EPLDa.

With its compact, bearingless, maintenance-free design, the new TF Torque Flange Sensor from Magtrol brings many appealing advantages to torque measurement applications. The TF’s high torsional rigidity supports direct mounting on the machine shaft or flange, avoiding the use of couplings on one side. This allows easy integration into a test system, shortens the overall length of the test bench and reduces costs. Based on strain-gauge technology, the TF Sensor’s precise telemetry system enables highly accurate signal transmission. A signal amplifier mounted in the measuring flange amplifies the measuring signal, modulates it to high frequency and transmits it inductively (via the HF transmitter) to the receiver. In the receiver, the digitized torque signal is transformed into an analog output signal of ±10 VDC. Rotational speed can be measured and converted to a TTL output signal with the optional speed pickup. more info www.magtrol.com
