Measuring transducers for strain gauge (with 4-arm strain gauge full bridge)
The measuring transducer DMS-MU is used for the transformation and isolation of the change in resistance of a 4-arm strain gauge full bridge 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 strain gauge measuring bridge is supplied with a constant reference voltage and the measuring signal is picked up in the form of a voltage difference. The input signal is amplified and transformed into an impressed direct current and in an impressed direct voltage. The input leads at terminals A, B, C and D are monitored for wire breakage. The galvanic isolation is realized using an optocoupler. Both outputs are no-load proof and shortcircuit proof. Connecting the two outputs is not permissible. An auxiliary voltage is required.
