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).
