Teknik Bilgi

Barksdale's CD1H and CD2H Housed Diaphragm Pressure Switches provide an ideal solution 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. These snap-action switches may be wired normally open or normally closed through a 3/4"-14 NPT conduit connector to free leads to 18". All models feature self-locking set screw adjustment and dials which are calibrated for increasing setting. For applications requiring a highly accurate switch in a durable package, Barksdale's CD1H and CD2H Housed Diaphragm Pressure Switches are the ideal choice. Stripped models are also available.
