Description

DS Series

DS switches have been designed for 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. Pressure switches can be supplied with SPDT, 2SPDT hermetically sealed (silver or gold plated) microswitches or other standard options. Typical application areas are in power sector, pharma, oil and gas, petrochemical, chemical & other industries.

Product Specifications
□ Storage temperature: Atmospheric temperature
□ Media Temp.:- for rubber diaphragms 80 degree C max, higher with metal diaphragms
□ Enclosure: Die cast aluminium to IP 66
□ Electrical output: Pneumatic
□ Process connection: 1/4 “BSP standard.

MT Series

MT Dual switches have been designed for applications requiring multiple set points. MT Dual pressure switches are housed in a cast aluminium 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 SS316L 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 snapaction 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.

Product Specifications:
□ Storage temperature: Atmospheric temperature
□ Operating ambient temperature: – 20 °C to + 60 °C
□ Media Temp.:- for rubber diaphragms 80 degree C max, higher with metal diaphragms Q Can be offered for higher temperatures with other capsule combinations
□ Setpoint repeatability: ± 1 % of FSR
□ Enclosure: Die-cast aluminium to IP 66
□ Switch output: SPDT, DPDT, hermetically sealed, gold plated contacts
□ Process connection: 1/4 “BSP standard, other options like flanges, triclover clamps, diaphragm seals available
