Description for Barksdale Model 371MT7 Position Indicator for Series II & Series III-L Valves

Barksdale's position indicators are sensitive feedback devices that can be attached to Series II & Series III-L valves to provide valve status feedback. Using Barksdale's know-how in electric switch technologies, the position indicator senses any of the three valve positions and signals this information through an electrical contact. With a housing constructed of all stainless steel material, this product is designed for use in heavy industrial environments and in the most demanding applications. The explosion proof rating is Division I, Class I.In applications where feedback from the valve is desirable, Barksdale's position indicator replaces such devices as proximity sensors, pressure switches and limit switches. Position indicators come already installed and calibrated on our Series II & Series III-L valves, saving installation costs for the customer.General Specifications*Housing Material:Stainless steelEnclosure:NEMA 4X, IP66Electrical Rating:Electrical Connection:Electrical Cable:Maximum Contact Resistance:Dielectric:30 VDC max, 500 mA (carry current)½” NPT rotating female conduit connection with 3 ft (36 in) cableUL listing, 4 conductors, 22 AWG TPE fl ame resistant jacket.Resistance to oils, fuels, and solvents100 milliohms100 megaohms minimum(@ 250 VDC)Switch Type:SPSTApprovals:cULus: Class I, Groups A (UL only), B, C & D, Class II, Groups E, F & G.
