Description
Wherever the process temperature
has to be indicated locally, and, at the same time, circuits are to be made or
broken, the bimetal thermometer with switch contact 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. 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 detachable
adjustment key (mounted to the junction box) in the window.
Switch contacts consisting of several contacts can also be set to a single
setpoint. Contact actuation is made when the actual value pointer travels beyond
or below the desired set value.
As switch contacts sliding contacts,
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.
