All models have MicroswitchTM snap switches to open or close a circuit on a pressure rise.
Primarily for use in vapor heating systems, but also may be used with liquids, air, and other noncombustible gases. Stainless steel diaphragm also allows use with ammonia, oxygen, distilled water, and similar media.
