Dwyer Instruments DA-7031-153-1 Pressure Switch
The Dwyer DA-7031-153-1 is a high-performance Bourdon tube pressure switch designed for precision control in commercial and industrial HVACR applications. This adjustable deadband pressure switch features an operating range of 0.125 to 15 psig, providing reliable setpoint management for low-pressure systems. Engineered with a brass Bourdon tube and a durable SPDT switch rated for 10 amps, the DA-7031-153-1 ensures long-term endurance and repeatability. The 1/4" male NPT process connection allows for straightforward integration into existing headers, while the vertical mounting requirement ensures the internal mechanism maintains its calibrated accuracy. For contractors managing industrial pressure control, this unit offers the mechanical robustness needed for steam, air, or non-combustible gas monitoring. By utilizing a general purpose enclosure (NEMA 1), this Dwyer DA series switch provides a cost-effective solution for indoor mechanical rooms where precise differential pressure adjustments are required to prevent short-cycling or system overpressure.
Key Benefits
- Adjustable Deadband: Provides a 6 psig adjustment range to fine-tune system cycling and reduce component wear.
- Bourdon Tube Accuracy: Utilizes a brass sensing element for superior sensitivity to pressure changes compared to standard diaphragm switches.
- High Electrical Capacity: The 10A SPDT contact allows for direct control of small motors or heavy-duty relay coils without additional hardware.
- Field Reliable: Proven mechanical design minimizes electronic failure points in harsh mechanical room environments.
Common Questions
How do you adjust the setpoint on a Dwyer DA-7031-153-1?
Adjustments are made via the external calibrated dials, which allow for independent setting of the high and low operating points within the 0.125 to 15 psig range.
Can this pressure switch be mounted in any orientation?
No, for peak accuracy and proper operation of the Bourdon tube mechanism, this model must be installed in a vertical position.
Is the DA-7031-153-1 suitable for corrosive fluids?
This model uses brass tube material and is intended for use with air, steam, or non-combustible gases that are compatible with copper alloys.
