Wherever the process pressure has to be indicated locally, and, at the same time, circuits are to be made or broken, the Model 232.30.063 switchGAUGE can be used.
Switch contacts (electrical alarm contacts) make or break an electric control circuit dependent upon the position of the instrument pointer. The switch contacts are adjustable over 80 ‰ of the scale range and are mounted predominantly below the dial.
The instrument pointer (actual value pointer) moves freely across the entire scale range, independent of the setting. The set pointer can be adjusted using a removable adjustment key in the window.
Switch contacts consisting of several contacts can also be set to a single set point. Contact actuation is made when the actual value pointer travels beyond or below the desired set point.
As switch contacts magnetic snap-action contacts, Reed switch, inductive contacts - for requirements to ATEX - or electronic contacts for triggering a PLC are available. For further information on the different switch contacts please see data sheet AC 08.01.
