PC-100 Proximity Probe Checker

PC-100 Proximity Probe Checker is a battery operated, easy to use instrument which checks sensor GAP and then indicates it on the LED bar integrated on the front panel.

There is also a LCD screen for displaying GAP voltage for better accuracy.
PC-100 can also be used to simulate any current sensor with constant current output.

Power is supplied by one internally mounted 9V alkaline battery.

Working mode can be selected by a side switch mounted on the left side. There is also a visual identification of the selected mode placed on the front panel.
The measured voltage is displayed on LCD screen and on LED diodes, which indicates the position of proximity sensor.

It is especially designed for fast checking of proximity probes used in the monitoring system. It also helps the operator to set up proximity probe in optimal position and/or to get information about the probe position in front of the shaft.

In CURRENT SOURCE mode, the instrument produces fixed current of 12mA. It is designed to get external 24V on this input and it generates fixed current through integrated current loop.
