Dewetron galvanically isolated multi-sensor amplifier range

Dewetron has introduced two galvanically isolated multi-sensor amplifiers with linearised analog output. The module connects to any thermocouple and measures additional voltage, Pt100 to Pt2000, constant current supplied bridges and resistance.

With the ±5 or 0 to 5 V output, the modules are suitable for signal conditioning any input signal. Together with 1 kV isolation and 160 dB CMR, the key features include high accuracy, a freely programmable measuring range, internal linearisation, programmable internal filters up to the 8th order and a 3 kHz bandwidth.

The galvanic isolation combined with a high CMR value of 160 dB, make it possible to use uninsulated thermocouples directly onto frequency converters and deliver precise temperature measurements.

To make optimum use of the dynamics of the measuring system, the modules provide freely programmable measuring ranges - for example thermocouple type T with +20 to +85 °C or Pt1000 with -50 to +480°C.

The modules have integrated filters to guarantee signal quality. Butterworth or Bessel filters are programmable in the 2nd, 4th, 6th or 8th order.
