Details for DPA-7033-153-61

DPA-7033-153-61 - Dwyer Instruments This Dwyer Instruments digital pressure gage measures 0-10 in. of water column (WC) pressure with a Â±0.5% full scale accuracy. It withstands overpressures to 25 psi and features a brass bellow and adjustment screw. For precise pressure measurement, this gage combines a brass bellow with a bright LED digital display. It also has an adjustable setpoint with visual red/green indication, making it suitable for use as a comparator.

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.
