Dwyer Explosion Proof Air Flow Switch

Series v8 field adjustable 1 to 6 inch pipe leak proof body chemical resistance.

Dwyer explosion proof air flow switch.

Air quality air flow switches. This category contains sensors with an electrical contact output at a specific air flow rate. The mcdonnell miller afe 1 series explosion proof air flow switch is used to prove flow in ducts in hazardous areas. Screw type on top of housing.

Temperature range 40 to 140 f 40. 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. Air and non combustible compatible gases. Applications include low air flow condition duct alarm fan monitoring damper feedback air handlers and air flow proving in hvac systems.

A supply voltage of 24 vdc 120 or 240 vac is required. 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 1950g is very compact about half the weight and bulk of equivalent conventional explosion proof switches. 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.

Applications include hvac applications process applications all weather applications and gas furnaces. 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. Explosion proof differential pressure switch combines the best features of the popular pressure switch with the benefit of natural gas compatibility.

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. Compact and easy access to the spdt relay. Dwyer s flow products included in this category are compact and explosion proof. Series 1620 high reliability repetitive accuracy within 1.

The switches control dampers according to flow and shuts down burners when air flow through heating coil fails. Dwyer flow switches are economical and reliable.
