Teknik Bilgi

Barksdale's CDPD1H and CDPD2H Housed Diaphragm Differential Pressure Switches are the answer for pressure control applications requiring tamper proof external adjustment and environments which require water-tight NEMA 4 housings. These pressure switches are available in single or dual control settings for both positive pressure and vacuum models, to 150 psi. The switches may be wired normally open or normally closed through a 3/4"-14 NPT conduit connection to free leads. All models feature calibrated dials for adjusting setpoints in units can be factory set upon request. For applications requiring a highly reliable, accurate switch in a durable package, Barksdale's CDPD1H and CDPD2H Housed Diaphragm Differential Pressure Switches are the ideal choice.
