Pressure Switches

Uses EnOcean® wireless technology to monitor pressure, vacuum, and differential pressures

High static pressure rating of 200 PSIG, low differential set points, NEMA 4X weatherproof enclosure

Customers say the extremely high sensitivity and great repeatability make this the best pressure switch ever made

Set point and deadband are easily adjustable, can be mounted in any orientation, simple & reliable

Designed with a 20 amp normally closed SPST switch for direct control of pumps and motors

Offer a versatile range of configurations allowing utilization of their many features

Field adjustable with simple indicating pointer, vacuum and pressure ranges, stainless steel construction

Designed for pressure, vacuum, and differential pressures

High-quality miniature snap-action switches with a high current capacity and high temperature rating

Specifically designed to stand up to extended duty applications

Offers field adjustments and can handle system pressures up to 6000 PSIG

Equipped with high proof pressure capabilities, available with either spade terminals or flying leads

15 A SPDT switch for direct control of pumps and motors, pressure, vacuum, or compound ranges available

Advanced design, precision construction, compact size, and repeatability; with set points from 0.07 in W.C. to 20 in W.C.

Highly repeatable differential pressure switch, easy-to-read analog pressure gage & adjustable switch setting,

Serve as a compact, low cost switch for gas fired furnaces and equipment

Combines the best features of the popular Dwyer® Series 1950 Pressure Switch with the benefit of natural gas compatibility

Manual Reset eliminate common problems associated with typical high duct static cutout installations

Small size and low price with 2% repeatability, wide range of models from 0.07 in W.C. - 85 in W.C.

Visual set point adjustment, adjustable null zone, and functions as a null switch

Visual set point adjustment in 5 standard ranges (0.05 in W.C. - 12 in W.C.) with repetitive accuracy within ± 1%

Diaphragm sealed leak proof construction provide high reliability repetitive accuracy within ± 1%

Proven and reliable sensing element available in ranges as low as 0 - 30 in w.c. or as high as 0 - 500 PSI
