Measuring transducer

Pt100 galvanically isolated for zone 1/21
  • For Pt100
  • Analog output 4 to 20 mA
  • Fault detector
  • Ex ia/ib
  • Two-, three-wire senors

EMV according to:

DIN EN 61000-6-3: 2007;

DIN EN 61000-6-4: 2007;

DIN EN 61000-6-1: 2007;

DIN EN 61000-6-2: 2006



The MODEX series includes a temperature measuring transducer mounted on-site in the same way as a rail-mounted terminal. The module transforms the signal received from the Pt100 temperature sensor into a proportional, load independent 4 to 20 mA output signal. The sensor circuit is intrinsically safe according to Ex protection type Ex ia. An output current exceeding the 4 to 20 mA range signals a senor fault (open/short circuit). The Pt100 temperature sensor can be operated in 2-wire or 3-wire circuits in Zone 0 or Zone 1.
