MT Series Dual Pressure Switch

Brand: Orion Instruments

MT Dual switches have been designed for applications requiring multiple set points. 

MT Dual pressure switches are housed in a cast aluminum enclosure. 

It has two independent pressure switch assemblies, with two independent scales to show approximate setpoints. 

The enclosure conforms to IP66 protection factor. 

The pressure capsule, at the bottom of the switch, comprises a pressure housing (either of 316L Stainless Steel or any other material like Monel, Hastelloy® C etc), and a pair of disc, nylon reinforced rubber / metal diaphragm and a plunger. 

The electrical changeover is through a snap action microswitch. 

2 SPDT switching can be provided as an option. other options like hermetically sealed microswitches etc, can be provided on checking feasibility, as per the order.
