PC-100 Proximity Probe Checker is a battery operated, easy to use instrument that checks the condition of a proximity probe by measuring the sensors Gap Voltage. LED's on the front of the meter in a gar graph format assist the user as he adjusts the Gap of the proximity probe to achieve the best gap for the probe. A constant current function also simulates mid-scale of any 4-20mA loop for a quick integrity check.

The 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.
