Measuring transducer for temperature (thermocouple, according to DIN EN 60 584)
The measuring transducer Th-MU is used for the transformation and isolation of a temperature-dependent voltage of a thermocouple into an impressed direct current and direct voltage signal. The calibrated double outputs are switchable between 0-20 mA and 0-10 V or 4-20 mA and 2-10 V.
The thermocouple constitutes a voltage source depending on the temperature. This voltage is supplied to an amplifier with integrated cold junction compensation. Following the linearization, the voltage is transformed into an impressed direct current and in an impressed direct voltage. The galvanic isolation is realized using an optocoupler. Both outputs are no-load proof and short-circuit proof. Connecting the two outputs is not permissible. An auxiliary voltage is required.
