System Description
The Model 175 liquid level system consists of the Model 175 Instrument and a CAPSEN
Capacitance Probe. The instrument consists of the electronic assembly (“puck”), a NEMA 4X /
7 explosion-proof enclosure, and an interconnection nipple. The enclosure provides two ¾″
NPT conduit openings for wiring. The windowed cover allows for viewing of process variables.
A magnet tool provides a way to set-up and calibrate the instrument without removing the cover.
The probe is a concentric-tube assembly designed to electrically and physically mate to the
Model 175, either directly or remotely (up to 10-feet). The operating or measurement length is
referred to as the “Active Length” while the “Overall Length” is the tip-to-tip length.
