Application
Linearized temperature measurement with Pt100...Pt1000, Ni100...Ni1000, or TC sensor.
Conversion of linear resistance variation to a standard analog current signal, for instance from valves or Ohmic level sensors.
Amplification of a bipolar mV signal to a standard 4...20 mA current signal.
Technical characteristics
Within a few seconds the user can program PR5331A to measure temperatures within all ranges defined by the norms.
The RTD and resistance inputs have cable compensation for 2-, 3- and 4-wire connection.
Continuous check of vital stored data for safety reasons.
Mounting / installation
For DIN form B sensor head or DIN rail mounting with the PR fitting type 8421.
