The OPLHC/OPLHACS Series Level gages are combination level-indicating gages with adjustable low- and high-limit switches. Limit switches can be wired directly to electric pilot circuits to operate alarms, shut down or start/stop pumps to maintain predetermined levels. 

Surface-mount or panel-mount enclosures are available for both model series. All models feature a 4-1/2 in. (114 mm) dial for easy viewing. Adjustable limit switches are accessible from the front of the gage.

Specialized models are available for specific applications involving engines or electric motors.

OPLHC/OPLHACS Series include two adjustable, pilot duty, pointer type contacts. Contacts have self-cleaning motion to enhance electrical continuity. Models are available with a rugged bourdon tube or a 316 stainless steel bellows sensing element for greater accuracy and sensitivity in lower ranges. 

OPLHBP/OPLHABPS Internal latching control relays are available to provide ON/OFF automation for electric motor applications.

OPLHC and OPLHACS series are available in indication only models (OPLHAGS). See the following pages to determine the model for your application.
