RFid (NFC) Signal Converter RTD / Thermocouples to 4..20mA - ATEX certified




  • <p>Signal converter rd Pixsys srl </p>
  • <p>Programming tool RFid (NFC) with RF programmer</p>

The transmitters for  DIN/B head convert a signal acquired by temperature probes PT100, PT1000 or Ni100 (with 2-, 3- and 4-wire connections) or Thermocouples into a  4..20 mA signal  (2-wire technology), current-loop. These converters ensure high accuracy on the reading scale with 16-bit conversion and possibility to rescale the output 4..20mA basing on input range.

Available also the version with galvanical isolation (cod. 2000.35.031).

ATEX marking:

II 1 G Ex ia IIC T3 ...T6 Ga

II 1 D Ex ia  IIIC T86...200°C Da

I  M1 Ex ia I T150°C Ma 


Quick and simple programming

The programming procedure uses the RFid (NFC) function with a dedicated programmer that allows you to perform all settings and any calibrations quickly without the need power and connect up the converter. An App for mobile and Android devices equipped with an NFC antenna makes it possible to program, modify and see data directly in the field or on the move.

2.8K Word non volatile (circular buffer) memory are dedicated to a data-logging function with a sampling time that can be set by the user.

The RF-Programmer software (available to download from the reserved access area of the website) allows you to download, view on the PC and print the temperature-time curve.
