The OPLHC/OPLHACS Series Level Swichgage instruments 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 Swichgage instrument.
Specialized models are available for specific applications involving engines or electric motors.
OPLHC/OPLHACS Series Swichgage instruments 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 Murphygage models (OPLHAGS). See the following pages to determine the model for your application.
