Drago DR44, DR48, DR49 Temperature Transmitters, Fixed Ranges

The temperature transmitters DR44, DR48, and DR49 convert the Pt-sensor signal to 0/4...20 mA and 0...5/10 V standard signals. The signal combination is selected by the order code, see table below. The 3-way isolation guarantees reliable decoupling of the sensor circuit from the processing circuit and power supply and prevents linked measurement circuits from influencing each other. The protective separation with high isolation level provides protection for personnel and downstream devices against impermissibly high voltage. The sensor signal is amplified, linearized, modulated and then electrically decoupled using a transformer. The isolated signal is then made available at the output, demodulated, filtered and amplified.
