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.

Within a few seconds the user can program PR5343B to measure within the defined Ohmic values.
Continuous check of vital stored data for safety reasons.
The transmitter is protected against polarity reversal.
PR5343B 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.
