Differential pressure switches

DP switches suit high line pressures and are available in piston models (up to 10,000 psig) and diaphragm models (up to 3,000 psig). Piston models range from 0-5 to 0-1000 psid while diaphgram models range from 0-5 in. H2O to 0-300 psid. Adjustable, hermetically sealed, reed switches control processes or initiate high/low alarms or indicators. They come with or without enclosures, including SPST, NO or NC, and SPDT switches.
