Dwyer Instruments DR-7031-153L-7 Pressure Switch
The Dwyer Instruments DR-7031-153L-7 is a precision-engineered Bourdon tube pressure switch designed for heavy-duty industrial monitoring. Built with a durable brass tube and a standard housing featuring a bottom connection, this unit delivers high repeatability of ±1% and sensitivity for critical process control. It features a 9-64 SPDT circuit and is specifically configured for a 5 to 150 psi range. As a semi-automatic controller, it includes a manual reset on pressure decrease, ensuring the system remains in a safe state until an operator intervenes. This snap switch is ideal for HVACR contractors managing air compressors, pump systems, and industrial boilers where manual reset lockout is a safety requirement. The visible calibrated dial allows for rapid setpoint verification without removing the cover, streamlining routine maintenance and field adjustments.
Key Benefits:- Enhanced Safety: The manual reset prevents automatic restarting during pressure drops, protecting downstream equipment.
- High Precision: Utilizing a brass Bourdon tube ensures excellent sensitivity and a long operational lifespan in non-corrosive environments.
- Field Adjustability: External thumbscrews allow for simple setpoint adjustment without exposing the internal electrical components.
- Industrial Durability: The SPDT snap action switch provides reliable electrical contact rated for standard 120/240VAC applications.
- What does "manual reset on pressure decrease" mean? The switch triggers automatically when pressure rises to the setpoint, but if pressure falls below that point, the circuit stays locked until the physical reset button is pressed.
- Can this switch be used for steam applications? Yes, but it requires a pigtail siphon to protect the brass Bourdon tube from live steam temperatures.
- How do I mount the DR-7031-153L-7? This model is designed for vertical mounting using the standard 1/4-inch NPT bottom connection.
