OPLHC/OPLHACS Series Swichgage instruments include 2-adjustable, pilot duty, pointer type contacts. Contacts have self-cleaning motion to enhance electrical continuity. Models are available with a rugged bourdon-tube or 316 stainless steel bellows sensing element for A “freeze-proof” sensor of 316 stainless steel with Buna-N rolling diaphragm, is available. The “freeze-proof” sensor (OPLHAFP) inserts approx., 2 in. (52 mm) inside a tank.

 

OPLHBP/OPLHABPS

Internal latching control relays are available to provide ON/OFF automation for electric motor applications.
OPLHC and OPLHACS series are avail-able in indication only Murphygage models (OPLHAGS). See Page 2 to determine the model for your application.
