The Series AT-ADPS ATEX/IECEx Approved Differential Pressure Switch is designed for pressure, vacuum, and differential pressure applications in hazardous areas. The dual scaled adjustment knob in inches water column and Pascals allows changes to the switching pressure to be made without a pressure gage. The switch is available with settings from 0.08 in w.c. (20 Pa) up to 20 in w.c. (5000 Pa). The silicone diaphragm makes this series ideal for use with air and other noncombustible gases. Flameproof enclosures are available in aluminum and can include a glass window for viewing set point status on the adjustment knob.

Series 1950 Explosion-Proof Differential Pressure Switch combines the best features of the popular Dwyer® Series 1900 Pressure Switch with an integral explosion-proof and weatherproof housing, making it an exceptional value for either application. It is CE, UL and CSA listed, FM approved for use in Class I, Div 1, Groups C and D, Class II Groups E, F, and G and Class III hazardous atmospheres (NEMA 7 & 9), Raintight NEMA 3 (IP54). Weatherproof features include a drain plug and O-ring seal in cover. Electrical connections are easily made by removing front cover. For convenience the set point adjustment screw is located on the outside of the housing. Twelve models offer set points from .03 to 20 in w.c. (0.0075 to 5 kPa) and from .5 to 50 psi (0.035 to 3.5 bar). The unit is very light and compact — about half the weight and bulk of other explosion-proof or weather-proof switches with separate enclosures.

Essential for industrial environments, the Series AT-1800 ATEX/IECEx Approved Low Differential Pressure Switch combines small size with 2% repeatability. Set point adjustment inside the switch allows for set point settings across 9 ranges from the low of .07 in w.c. to a maximum 85 in w.c. differential pressure. Series AT-1800 flameproof enclosures are available in aluminum and are ideal for low pressure hazardous area applications. Various housing options such as an over-pressure relief valve or external set point adjustment knob are available. External set point knob allows adjustment without opening the enclosure.

Differential pressure switch for monitoring overpressure, differential pressure, or underpressure of air and non-flammable, non-aggressive gases. Can be used as a fume cupboard or fan monitor or flow monitor to protect electrical heating coils, as a filter monitor, air pressure deficiency protection, or limit controller. Note: Once the differential pressure switch has switched a voltage > 24 V and a current > 0.1 A, the gold layer on the contacts is burnt away. After that, the differential pressure switch can only be operated with this or a higher power. Note: The hose set JZ-06 / 1 is not included in the scope of delivery and must be ordered separately.
