WIKA PSM-700 LIQUID DP SWITCH FOR WATER APPLICATIONS

The model PSM-700 mechanical pressure switch has been designed for control and monitoring applications. The measuring element is a fully welded bellow made of stainless steel 316L. This corrosion-resistant pressure switch is suitable for a broad range of media used in the process industry.

The case consists of a high-grade aluminium alloy with which the pressure switch can withstand the harsh operating conditions of the process industry. The model PSM-700 is equipped with UL listed micro switches to ensure high endurance with durable operation and long service life.

The model PSM-700 has a high switch point repeatability of = 0.5 %, 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. With the available tamper proofing, unauthorised adjustment of the switch point can be prevented.

Applications:

• 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

Features and Benefits:

• Switch differential adjustable within a wide range of up to 60 % of the setting range to realise flexible on/off controls
• Robust aluminium case
• Switch point repeatability of = 0.5 % for reliable switching
• High-quality micro switches with long service life
• Up to 2 possible positions for electrical connection
