TQ402 111-402-000-013 Proximity Transducer

This proximity system allows contactless measurement of the relative displacement of moving machine elements.

It is particularly suitable for measuring the relative vibration and axial position of rotating machine shafts, such as those found in steam, gas and hydraulic turbines, as well as in alternators, turbo-compressors and pumps.

The system is based around a TQ402 or TQ412 Non-contact transducer and an IQS450 signal conditioner. Together, these form a calibrated proximity 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.
