Bellow Type Pressure Switch

Pressure Switch – Bellow Type – Series GH 901:
SWITZER GH-901 (WIKA PS-901) mechanical pressure switch has been designed for control and monitoring applications. The sensing element is a hydraulically formed seamless Phosphor Bronze or Stainless Steel Bellows mounted external to the weather proof switch housing suitable for broad range of media in process industry.
Pressure Switch GH-901 has a high switch point repeatability ±0.5% of FSR, which enables reliable switching. Adjustable switch differential to a wide range of up to 60% of the setting range to realise flexible on/off controls. This wide setting range is often needed for the on/off control mode of cyclic applications.

Pressure Switch – Bellow Type – Series PSM 520 / IPS:
INDFOS IPS (SWITZER PSM-520) is used in industrial control, monitoring and alarm applications.
The switch point can be specified by the customer on site. The instrument can switch electrical loads of up to AC 230 V, 50/60 Hz, 10 A. Pressure Switch IPS (SWITZER PSM-520) pressure switch offers many application possibilities with non-corrosive media like oil, water and air.
Pressure Switch – Bellow Type – Series PSM 550 / RT:
INDFOS RT (SWITZER PSM-550) pressure switches utilise seamless bellows as the sensing element. Simplicity of design and easy of installation has been stressed for reliable use, even in applications where shock and vibrations are present. The sensing element is suitable for a variety of process fluids. Applications for this Pressure Switch include pumps, compressors, filters, evaporators, heat exchangers, lubrication systems, hydraulic systems, marine equipment, heating and air conditioning equipment, turbines, generators and circuit-breakers etc.
