Details for DPA-43-153-62E

Dwyer Instruments DPA-43-153-62E Differential Pressure Switch The Dwyer Instruments DPA-43-153-62E is a versatile differential pressure switch designed to manage pressure levels in industrial applications. With a measurement range of 0-20 inches of water column (WC), it effectively monitors the pressure differential in air or compatible gases. Its robust construction ensures reliability and durability, while its compact size allows for easy installation in space-constrained environments. The DPA-43-153-62E features a single-pole, double-throw (SPDT) switch with a maximum pressure rating of 100 WC, making it ideal for both low- and high-pressure applications. Its adjustable set point allows for customization to specific pressure requirements, ensuring accurate and responsive pressure control. This switch is commonly used in HVAC systems, fluid handling, and process control industries, making it a valuable tool for industrial engineers and maintenance professionals. Our HVAC supply store offers competitive pricing and swift shipping on the DPA-43-153-62E and other essential industrial components. Contact us today to fulfill your industrial supply needs!

Series DP Double Bellows Differential Pressure Switch

Visible Setpoints, Adjustable or Fixed Deadband . . . High Pressure Ranges

Two opposing bellows combine maximum sensitivity and vibration resistance at a moderate cost in the Series DP Differential Pressure Switches. Both set and reset points are easily adjustable through non-interactive, externally accessible controls. Visible setpoint indicators simplify changes. SPDT snap action switch, 316 stainless steel or brass bellows, flanged steel housing. Rated pressures to 600 psig.

A wide variety of switches and circuit styles enables exactly the specific type of control function needed for any system. Mercury switches are a good choice for humid areas while snap switches are better able to resist vibration. Various operations possible include single adjustment - fixed deadband, double adjustment - adjustable deadband, manual reset (increasing or decreasing pressure) and two stage with each SPST or SPDT switch independently adjustable. Standard enclosure is NEMA-1 style. Optional weatherproof construction is for outdoor use and explosion-proof enclosure meets requirements for Class I, Groups C & D; Class II, Groups E, F & G.
