The display, with its 9 mm high digits, was designed to be as large as possible and was made at a slight angle, so that the displayed pressure can be easily read from a distance. Proven and robust LED technology has been used, with a 14-segment display employed so that alphanumeric messages are well represented. The buttons used to set the switch parameters have been maximised in their size and ergonomically arranged. Their tactile feedback supports, and thus enables, usage without additional assistance. The three keys ensure easy, intuitive menu navigation. This menu navigation is in accordance with the new VDMA Standard. This VDMA Standard Form for fluid sensors (24574-1, Part 1, pressure switch) has the aim of simplifying the use of pressure switches by standardising the menu navigation and display.
Flexible and adaptable
During commissioning the CPS 1000 can be adapted, flexibly, to the mounting conditions. Due to the dual rotatability of the housing through more than 300°, the display can be adjusted independently of the electrical connection. The display, therefore, can always be aligned towards the operator while the M12 connection can always be aligned to suit the desired cable run. If the equipment is to be installed overhead, the display can also be turned electronically through 180°.
During development, great importance was attached to providing a robust design and an appropriate choice of materials. For this reason, both the housing and the threaded connector for the electrical plug are made from
stainless steel. Overtightening or breaking the plug is thus almost impossible.
