Vibration transmitters measure radial shaft displacement and shaft thrust position

September 2006 Maintenance, Test & Measurement, Calibration

The new TXR and TXA proximity probe transmitters from Metrix represent a step forward in vibration proximity transmitters. The model TXR 5465 measures radial shaft displacement and the TXA 5488 is used to monitor shaft thrust position.

This new transmitter is a 2-wire loop-powered transmitter combining an eddy current probe driver and a signal conditioner in a single package. It provides a 4-20 mA signal proportional to overall peak to peak displacement and operates with Metrix probes and extension cables as well as four major probe systems. A separate probe driver is not required. A DC voltage output proportional to probe gap is also available.

Features include:

* Cost-effective alternative to dedicated rack mount monitors.

* Loop-powered driver/transmitter.

* Compatible with four major probe systems

* Easily calibrated to non-standard shaft material.

* DIN rail mounting.

* BNC for access to dynamic output.

* Environmentally hardened.

Machines using shaft monitoring:

* Oil lubricated bearing machines.

* Centrifugal pumps.

* Turbo compressors.

* Steam and gas turbines.

* Fans and blowers.

* Gearbox shafts.

* Generators.

* Large electric motors.
