Pressure Switch
Models PS901, PS902, PS903
- Pumps for process applications (e.g. water treatment, water supply and distribution)
- Industrial hydraulics (e.g. pressure control, oil pressure monitoring and overpressure protection in process lines)
- Discharge control for automatic sprinkler systems
- Compressor controls in pneumatic applications
- Switch differential adjustable within a wide range of up to 60% of the setting range to realise flexible on/off controls
- Switch point repeatability ±0.5% of FSR for reliable switching
- Compact dimensions enables panel mounting
Description
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.
