sensata空調機械產業專用壓力传感器PLCD Sensor

PLCD-Displacement Sensors (Permanentmagnetic Linear Contactless Displacement Sensors) basically consist of a special soft magnetic core surrounded by a coil, wound arround its entire length. On each end of the core there is a second short coil.

A permanent magnet guided close to the sensor causes localized magnetic saturation and thereby a virtual pision of the core.

The position of the saturated area along the sensor axis can be determinated by the coil system.

The sensor is supplied by an external electronic module or by an integrated circuit which also produce the output signal.

The output signal is linearly dependent on the position of the magnet. The signal can be conditioned by a standard electronic module, which gives either a current output (4 ... 20 mA) or a voltage output (0 ... 5 V or 0 ... 10 V).

Customer specific interfaces are possible.
