About Dwyer DXW-11-153-3 Differential Pressure Switch

Dwyer DXW-11-153-3 Differential Pressure Switch

DXW-11-153-3 - DWYER WET/WET DIFFERENTIAL PRESSURE SWITCH, 25 - 50 PSI, SPDT, 1/4" NPT FEMALE

DESCRIPTION

The Series DX is a Differential Pressure Switch that Makes a contact output based on the differential between two pressure sources. Wetted materials of brass and flouroelastomer are suitable for use with most gases and water based solutions. The switch can be used for low differential pressure indication with set point on a decrease of pressure as low as 1 psid (0.07 bar). Differential set point ranges are available from 2.5 to 75 psid (0.17 to 5.17 bar) on increasing differential pressure and 1.0 to 67 psid (0.07 to 4.62 bar) on decreasing differential pressure. Unit features a high static pressure rating of 200 psig (13.8 bar). Weatherproof, UL type 4X, enclosure for dust laden, outdoor, or wash-down installation environments. Externally adjustable set point, integral mounting flange and a removable electrical terminal block for quick and easy installation.
Weatherproof housing provides protection in the harsh, wet or dirty environments insuring switch's long-service life

Removable terminal block reduces installation time

Flexible and Precise Pressure Monitoring

With a differential pressure range of 0-150 In. W.C., the DXW-11-153-3 is ideal for monitoring building pressure or gas flow. External setpoint adjustment allows field operators to quickly tune the switch, while the diaphragm-operated sensor and silver contacts ensure consistent actuation. Its approximate 10% deadband and high repeatability further ensure stable operations.

Easy Installation and Versatile Mounting Options

Mounting the DXW-11-153-3 is straightforward, thanks to the included bracket, and the compact size allows for both surface and panel mounting. Threaded 1/4" female NPT process connections make hookup simple, while the user-friendly design caters to quick setup and minimal downtime on site.

FAQ's of Dwyer DXW-11-153-3 Differential Pressure Switch:

Q: How does the Dwyer DXW-11-153-3 measure differential pressure?

A: The DXW-11-153-3 uses a diaphragm-operated sensor to detect differential pressure changes between two points in a gas flow system. When the set threshold is reached, the internal snap switch actuates, indicating a pressure event.

Q: What environments is the DXW-11-153-3 suitable for use in?

A: With its weatherproof Type 4X (IP54) rated enclosure and durable aluminum die-cast construction, this switch is designed for industrial settings, including building pressure monitoring applications both indoors and in protected outdoor environments.

Q: When should I use an external setpoint adjustment?

A: The external knob allows you to change the setpoint without opening the enclosure, making it convenient for on-site tuning or adjustments whenever process requirements change or periodic recalibration is needed.

Q: Where can I mount the DXW-11-153-3 pressure switch?

A: This switch supports both surface and panel mounting, and includes a mounting bracket, allowing you to install it in control panels, equipment racks, or directly to walls as needed.

Q: What benefits does the SPDT snap switch provide?

A: The SPDT snap switch offers quick and reliable electrical switching with a 15A rating at 125/250VAC, ensuring dependable performance in control applications and allowing for flexible wiring configurations.

Q: How accurate and repeatable is this differential pressure switch?

A: The DXW-11-153-3 features an accuracy of 2% of full scale and a repeatability of 1% of the pressure range, ensuring reliable and consistent pressure monitoring in critical processes.
