Inductive linear transducers IW120

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.

At Embro, we develop and produce customised, textile-based surface sensors in large dimensions. Applications include: > pressure sensors > impact sensors > detection and monitoring of composites > surface temperature sensors > area sensors for humidity and damage sensing > inductive sensors > capacity sensors

■ Configurable output signal (4...20 mA, 0...20 mA, 0...5 V, 0...10 V, ±5 V, ±10 V) ■ DIN rail mounting ■ Low residual noise ■ Built-in cable break detection with alarm-output

BEDIA level monitoring sensors are used to monitor the filling levels of liquids. The sensors detect when a filling level is exceeded or falls below a limit. Water-based liquids like coolants, AdBlue®, fresh water, waste water and oil-based liquids like motor oils, hydraulic oils, fuels and brake fluids can be monitored. Operating Principle The function of the sensor is based on the capacitive principle. It detects the change in capacitance that occurs when an electrode surrounded by air is immersed into a liquid medium. This change in capacitance at the electrode of the sensor excites an oscillator. This signal is processed by a microcontroller-based evaluation circuit which activates or deactivates an output stage. Types of Media The level monitoring sensors are designed for two different media types: For electrically conductive liquid media with relative permittivity within a range of εr 35 … 85 (water, coolant, water/glycol mixture) For electrically non-conductive liquid media
