MD Series

MD switches have been designed for applications that require robust, long lasting switches, coupled with high accuracy and repeatability, in adverse conditions. By using appropriate capsules and wetted parts, M D series pressure switches can be used for thousands of applications. A wide choice of electrical elements including SPDT, DPDT, gold plated contacts make these switches ideal for a variety of critical applications. A wide scale, when opted for, offers ease of setting, given the smaller least counts.

□ Switch output: SPDT, DPDT, hermetically sealed, gold plated contacts
□ Process connection: 1/4 ” BSP standard, other options like flanges, triclover clamps, diaphragm seals available.

DS Series

DS Air Relay switches have been designed for the zone 0 applications requiring multiple set points, but with only one or two process connections. Typical applications are for alarm and trip functions. Some other are to keep pressure between two limits HI and LO, with independent signals. Other applications are for HI and HI-HI limits or LO and LO-LO limits in the same pressure switch.
Typical application areas are in hazardous & nonhazrdous locations like power sector, pharma. oil and gas, petrochemical, chemical & other industries.
