  • Mounting on 1.5”–2” pipe bracket or on wall/bulkhead.

Application

  • Linearized temperature measurement with TC and RTD sensors e.g., Pt100 and Ni100.
  • HART communication and 4…20 mA analog PV output for individual, difference or the average temperature measurement of up to two RTD or TC input sensors.
  • Conversion of linear resistance to a standard analog current signal, e.g. from valves or Ohmic level sensors.
  • Amplification of bipolar mV signals to standard 4…20 mA current signals.
  • Up to 63 transmitters (HART 7) can be connected in a multidrop communication setup.

Technical characteristics

  • NAMUR NE43 and NE89.
  • HART protocol revision can be changed by user configuration to either HART 5 or HART 7 protocol.
