Low-pressure differential commercial pressure switch

Winters Instruments has announced the WPS series low-pressure differential switch for monitoring and controlling air and non-aggressive gases. Designed to handle pressure, vacuum, and differential pressures, the Winters Instruments switches are suitable for HVAC applications and simple to integrate into BAS systems, the company says.

The adjustment knob allows for field changes to be made without the use of a reference pressure gauge.

The silicone diaphragm is able to sense pressure as low as 0.08 in. of water (16 Pa) up to 20 in. of water (4,000 Pa).
