Up to 4 switch contacts per instrument
Gauges with inductive contacts for use in hazardous areas
with ATEX approval
Gauges with electronic contacts for PLC applications
Description
Wherever the process pressure has to be indicated locally,
and, at the same time, circuits are to be made or broken, the Model 632.51
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 the full extent of the scale range (see
DIN 16085), and are mounted predominantly below the dial, though also partly on
top of 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.
The pressure gauge is manufactured in accordance with DIN
16085 and fulfils all requirements of the relevant standards (EN 837-3) and
regulations for the on-site display of the operating pressure of pressure
vessels.
As switch contacts magnetic snap-action contacts, inductive
contacts - for requirements to ATEX - or electronic contacts for triggering a
PLC are available.
