Our Products
We offer a complete product range of Pressure Switches and Differential Pressure Switches
Indfos pressure switch type PS/PSU is a triple pole device, meant to regulate pressure in small air compressors and water pressurization plants.
These switches cut off a 3-phase power supply when the pressure rises to a preset value and cuts in the power supply when the pressure falls to another predetermined value. Both cut off and cut in pressures are independently adjustable. All models are provided with a manual cut off switch (except PSU15X). Type PSU switch is additionally provided with a relief valve, which ensures load free starting of the compressor.
Indfos D Series Differential Pressure Switches are produced using technology provided by Dresser Industries USA (ASHCROFT Division). These are sturdy, robust and precise devices for use in process industries.Available in various ranges covering differential pressures from 25 mm to 42 kg/cm2 ranges, these switches utilize a dual diaphragm sealed piston sensor which is capable of withstanding extremely high static pressures and at the same time provides set point repeatability of 1percentage. Diaphragms are available in Buna-N, Viton, Teflon, Kapton, Stainless steel & Monel construction making the switch suitable for virtually any process fluid.
Enclosures are available in weather proof (IP 66) and explosion proof (II A, B & C) versions and are die cast aluminium as a standard. A wide variety of 1 SPDT or 2 SPDT microswitches including hermetically sealed microswitches are available to meet different requirements of electrical ratings and environmental conditions.
