Dwyer Instruments DA-7031-153-2 Pressure Switch

Dwyer Instruments DA-7031-153-2 Pressure Switch

The Dwyer Instruments DA-7031-153-2 Pressure Switch is a high-sensitivity vacuum pressure switch designed for precision control in demanding HVACR and industrial process environments. This Bourdon tube pressure switch features a 0 to 30" Hg vacuum operating range, making it an essential component for monitoring vacuum systems, pump control, and compressor safety. The SPDT snap-action switch is housed in a rugged general purpose enclosure (NEMA 1), providing 10 Amp electrical capacity at 120/240VAC without the use of mercury. Engineered for field reliability, the DA-7031-153-2 includes external setpoint adjustments with a visible calibrated dial, allowing technicians to verify settings at a glance. The 13.5" Hg adjustable deadband provides superior flexibility when calibrating reset points for specific mechanical equipment requirements. With a 1/4" male NPT process connection and a durable brass Bourdon tube, this industrial pressure control ensures ±1% repeatability for consistent performance over time. This unit is optimized for vertical mounting to maintain its high degree of accuracy and long-term stability in the field.

  • Visible Calibrated Dial: Allows for immediate on/off indication and simplified setpoint verification without removing the cover.
  • Adjustable Deadband: Provides a 13.5" Hg range to fine-tune the differential between high and low operating points.
  • Heavy-Duty Construction: Features a brass Bourdon tube and a 10 Amp SPDT switch for reliable switching in vacuum pump and HVAC applications.
  • Precise Repeatability: Maintains a ±1% full-scale repeatability to ensure consistent system response under varying conditions.

Common Questions:

How do you adjust the setpoints on the DA-7031-153-2?
This model utilizes two external thumbscrews to adjust the high-pressure operating point and the reset point independently across the full scale.

What is the maximum temperature limit for this pressure switch?
The standard temperature limit for the DA series is 180°F (82°C). For higher temperature media, we recommend using a siphon or remote mounting.

Can this vacuum switch be mounted in any orientation?
While the internal mechanism is robust, it is designed specifically for vertical mounting to ensure the highest degree of sensitivity and accuracy.
