Battery-operated milliohmmeter - RESISTOMAT® 2320

Fast and accurate measurements of the smallest resistance values are possible with the milliohmmeter RESISTOMAT® model 2316. Due to the rugged aluminium injection moulding desktop housing with membrane keypad it is suitable for use in laboratory and industrial environment likewise. Wires and coils can be measured with temperature compensation. The temperature of the sample is measured with a Pt100 or pyrometer and the resistance is then corrected to the equivalent at e.g. 20 °C (adjustable) in the instrument. The application range is very wide such as the measurement of: — transformer motor coil windings — coils of all kind — cables and wires on the drum or as meter samples — switch and relay contacts — heating elements — fuses — connections and transitions at power rails and many more Specific characteristics: — Autorange — Temperature compensation for all materials — Thermal e.m.f. compensation — Input voltage protection up to effectively 400 V rms

Model 9180 supports force, pressure and torque sensors operating on the strain gauge principle, as well as the connection of position and angle sensors in potentiometer or DC/DC configuration. It also allows the measurement of process signals ± 1 V/ 5 V/ 10 V or 0 ...1 mA, 0(4) ... 20 mA. The current measured value is indicated on the 14 mm high LED main display, while a second display located directly below provides a reading of the peak value. The display is particularly suitable for highly accurate measurements due to the high accuracy of 0.1%. It is also possible to monitor up to 4 limit values and provide the results via relay or transistor outputs. Thus the process value display can be used for classification, process and control tasks. The current measured value is frozen on the display by activating an external HOLD signal. The TARE function is useful for balancing out previous loads for example.

The SENSORMASTER 9163 covers a wide range of applications in which process values need to be measured, displayed, analyzed and transferred to higher-level control systems. Typical applications include measuring geometric values in production, for instance differential measurements, or testing material properties in the laboratory. The measured values can be transferred via USB, RS232 or analog output. Features: — For force, pressure or torque measurements using strain gauge sensors — For position or angle measurement using potentiometric or DC/DC sensors — For temperature measurement using Pt 100 sensors or thermocouples — Optional multi-channel model — Optional Profibus or serial interface — 0.1 % measurement accuracy plus sensor-specific linearization — Range of mathematical functions (e.g. differential measurement) — OK/NOK feedback on multi color display and via 4 alarm limit outputs — High sampling rate (500/sec.)

Based on its specifications, this device can be used in various applications. It is especially suitable for resistance measurement on insulating materials such as e.g. cable insulations, foils, textiles, surfaces, insulating liquids,etc. With a test voltage of 45 V, 100 V, 250 V and 500 V the device fulfi ls most test specifi cations such as e.g. DIN 51953, 53482 and 54345. The guard switching allows single resistance measurements in a triangle wiring. This could be e.g. a two line cable with common shield or the measurement of insulating materials on a guardring measurement cell. The selection of the measurement range is done manually or automatically. Fast subsequent measurements can be realized by the internal limit value indicator. When the measured value exceeds the limit the limit value indicator switches and activates a potential-free relay output. The megohmmeter RESISTOMAT® model 24508 is the right instrument for its use in laboratory as well as in industrial applications.
