The strain gauge transmitter periodically samples signals from strain
gauges. These signals are converted into output signals proportional
to the measured values.
The output signal can be a voltage or a current.
3-port isolation with protective separation up to 300 V AC/DC accord-
ing to EN 61140 ensures optimum protection of personnel and equip-
ment as well as unaltered transmission of measuring signals.
