Applications  Machine Shaft Position  Turbine Differential Expansion  Harsh Environments Features  Switch selectable system cable lengths 5m, 7m and 9m.  LED indication of selected length.  3.5mm socket for gap voltage monitoring.  Double screened cable for high noise immunity.  Snap lock and shake proof cable connection.  Excellent repeatability on replacement of probe, extension or driver.  Compliant with standard API 670. The XPR08 proximity probe system consists of a calibrated probe, extension cable and driver. Utilising the eddy current principle, this combination forms a tuned circuit with the target material and variations in probe face to target distance are detected in this circuit by the driver. This provides a linearised voltage output proportional to target gap with a nominal sensitivity of 1.97 mV/um and a range of up to 8.0 mm. This type of measurement system provides highly accurate (resolution typically to a few micro-meters) relative positional measurements, for harsh environments up to 180 °C. The driver unit offers selectable system lengths of 5 m, 7 m or 9 m, with a front panel green LED indicating the selected option. The gap voltage monitoring socket assists with commissioning the probe system; a volt meter can be connected directly to the driver through the 3.5 mm standard audio socket to display the gap voltage at the point of installation and the probe mechanical gap can then be adjusted to suite the application.
