operating sites with lowest possible installation expense and
a 4..20 mA two wire system which is complying to industrial
standards. The sensing elements T1 and T2 measure the
temperature at each location by a platinum resistance
sensor at the same time. T1, as well as recording
temperature, includes electronics which build up the
differential of both temperatures (T1-T2) and emits this via a
current amplifier as a proportional 4..20 mA signal. Two
different characteristic curves are available as a standard.
The electronic circuit involves a total of < 4 mA, so that a
two wire system can be used.
* simple recording of differential temperature
* self assembly connectors
* large distance possible between two sensing elements
* variable rotating plug connection
* different characteristic curves possible
