Description: 
----------------------------------------------------------------------------------------------------------------

The TQ902/TQ912, EA902 and IQS900 form proximity measurement chains, from Meggitt’s vibro-meter® product line.

TQ9xx-based proximity measurement chains allow contactless measurement of the relative displacement of moving machine elements, and provide an output signal proportional to the
distance between the sensor tip and the target.

Accordingly, these measurement chains are ideally suited 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.

A TQ9xx-based proximity measurement chain consists of a TQ9xx proximity sensor, an optional EA90x extension cable and an IQS900 signal conditioner, configured for a particular industrial application. 

The EA90x extension cable is used to effectively lengthen the front-end, as required. Together, these form a calibrated proximity measurement chain in which each component is interchangeable.
