Dwyer Explosion Proof Air Flow Switch

Temperature range 40 to 140 f 40.

Dwyer explosion proof air flow switch.

A supply voltage of 24 vdc 120 or 240 vac is required. Air and non combustible compatible gases. Dwyer s flow products included in this category are compact and explosion proof. The ase 1 has an external adjustment of setpoint so one does not have to remove the explosion proof housing.

Easy access to the spdt relay and power supply terminals is provided by removing the top plate of the aluminum housing. Series v8 field adjustable 1 to 6 inch pipe leak proof body chemical resistance. This category contains sensors with an electrical contact output at a specific air flow rate. They monitor liquid gas and air flows.

Series 1950 set points from 03 to 20 in w c explosion proof and weatherproof. Applications include proof of boiler flow air conditioning controlling of dampers according to flow and protecting pumps motors and other equipment against low or no flow. Monitor flow in 1 2 to 2 12 70 to 50 80 mm pipe explosion proof compact flotect mini size flow switches are compact and designed to monitor liquid gas or air flows. The mcdonnell miller afe 1 series explosion proof air flow switch is used to prove flow in ducts in hazardous areas.

Explosion proof differential pressure switch combines the best features of the popular pressure switch with the benefit of natural gas compatibility. Applications include low air flow condition duct alarm fan monitoring damper feedback air handlers and air flow proving in hvac systems. Set points from 03 to 20 in w c explosion proof and weatherproof view all product images 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. Series 1620 high reliability repetitive accuracy within 1.

Air quality air flow switches. Dwyer pressure switches are explosion proof atex approved weatherproof compact and low cost. The 1950g is very compact about half the weight and bulk of equivalent conventional explosion proof switches. Some applications are control dampers according to flow signals alarm shuts down burner and protects pumps motors and other equipment against low or no flow.

Applications include hvac applications process applications all weather applications and gas furnaces. The switches control dampers according to flow and shuts down burners when air flow through heating coil fails.
