| Pressure Switches For Air Compressors Type Ps And Psu |
Product Description
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.

| Economy Pressure Switches For Industrial App. Type Ips |
Product Description
Industrial pressure switch IPS, is an electromechanical device that senses changes in pressure and provides electrical contact closure at predetermined values. IPS pressure switch may be used to energize an alarm or may directly control the process by cycling pumps, shifting valves etc.
IPS is the most economic device in our wide range of pressure switches. The construction is simple, yet sturdy. The mechanism is enclosed in a dust proof mild steel casing and all parts are rust proofed for long life. Range and Differential values can be set independently and the device has clearly read out setting scale.

Product Description
Award-winning in design and functionality
The successful design and the excellent functionality of the WIKA switch family were already confirmed by winning the “iF product design award 2009″ for the electronic pressure switch.
The robust LED display has been designed using 9 mm high characters (the largest possible) and with a slight incline in order to make reading the pressure as easy as possible from a long way off. A 14-segment display has been used, since it represents text very well.
The 3-key operation makes simple, intuitive menu navigation possible, with no need for additional assistance. The menu navigation conforms to the latest VDMA standard. A new VDMA standard for fluid sensors (24574-1, part 1 – pressure switches) has the aim of simplifying the use of pressure switches by standardising menu navigation and display.
The control keys have been designed as large as possible and are arranged ergonomically to ensure fast and easy adjustments. Operation without any additional assistance is made easier through the tactile feedback.
