D1S, D2S, D1H, D2H Series Pressure Switch
Brand: BarksdaleBarksdale's Diaphragm Pressure Switches offer superior accuracy in a robust package, making them the ideal solution to your industrial pressure control needs.
Diaphragm switches are ideal for applications demanding instrument class accuracy and where pressure pulsations are less than 25 cycles per minute. Available in various pressure ranges up to 150 psi, diaphragm switches are suitable for use in either positive pressure or vacuum applications.
Single, and dual, and triple circuit models are available.
Housed models (D1H & D2H) feature a durable, anodized aluminum enclosure with an integrated 1/2" NPT conduit connector, a tamper-resistant cover for the setpoint adjustment screws, and are rated to NEMA 4 as a standard.
For applications requiring a highly accurate switch in a durable package, Barksdale's Diaphragm Pressure Switches are the ideal choice.
