Application

  • Conversion of resistance variation to standard analog current signals, e.g. from Ohmic level sensors or valve positions.
  • User-defined linearization function can be activated.

Technical characteristics

  • Within a few seconds the user can program PR5343A to measure within the defined Ohmic values.
  • Continuous check of vital stored data for safety reasons.
  • The transmitter is protected against polarity reversal.
  • PR5343A is configured to the current task by way of a PC, the PReset software and the communications interface Loop Link.
  • The PRelevel configuration tool included in the PReset software has been developed specifically for the configuration of level applications. Among other things, it contains a function for ”on line” measurement of input span as well as a linearization function for volume linear output from horizontal cylindrical tanks.

Mounting / installation

  • For DIN form B sensor head or DIN rail mounting with a special fitting.
