IQS450 204-450-000-002 A1-B21-H10-I0 Proximity Measurement System

Product Details:

Additional Information:

Description:

The system is based around a TQ401 non-contact sensor and an IQS450 signal conditioner. Together, these form a calibrated proximity measurement system in which each component is interchangeable. The system outputs a voltage or current proportional to the distance between the transducer tip and the target, such as a machine shaft.

The IQS450 signal conditioner contains a highfrequency modulator/demodulator that supplies a driving signal to the transducer. This generates the necessary electro-magnetic field used to measure the gap. The conditioner circuitry is made of high-quality components and is mounted in an aluminium extrusion.
