Transmissor de Nível 2 Fios
Fabricante
Transmissor de Nível 2 Fios
Principais características

Potentiometer or Ohmic input
Programmable sensor error value
High measurement accuracy
Unique process calibration function
Programmable via standard PC

VISÃO GERAL

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.

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

DETALHES TÉCNICOS

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.
