The model PS-901, 902, 903 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.
The model PS-901, 902, 903 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. The switch point can be specified on site.
