The mechanical WIKA PSM-700 pressure switch is 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 WIKA PSM-700 pressure switch is equipped with UL listed micro switches to ensure high endurance with the durable operation and long service life. The WIKA PSM-700 pressure switch 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 tamper-proofing, which is available as an option, unauthorised adjustment of the switch point can be prevented.

The WIKA RLS-2000 float switch is a reliable and inexpensive float switch made of high-quality plastic. The WIKA RLS-2000 float switch is particularly suited for measuring the levels of aggressive and corrosive media, such as bases and acids. For cost-sensitive applications such as the monitoring of levels or overflow and dry-run protection, float switches are an ideal solution. The WIKA RLS-2000 float switch detects the level using a permanent magnet and frictionless reed contacts at up to 4 defined switch points, without contact and thus free from wear. Integration as a limit level switch is simple, convenient and fast, because no adaptation or calibration is required during installation. The robust design minimises service and maintenance costs.
