  Details of Temperature Measuring (range of applications)







MEASURING TRANSDUCERS & MEASURING POINT CHANGE-OVER Measuring transducers supply a linear output signal which is proportional to the measured value.

ZIEHL delivers measuring transducers for input signals DC 0/4-20 mA, Pt 100, thermoelement, resistance and frequency. Output signals are: DC 0/4-20 mA, 0-10 V or frequencies. Frequency signals can be easily evaluated by digital inputs of PLC's. In combination with our check switch/data scanner MUM 8 up to 8 signals can be connected to one input (i.e. display or PLC).
