CA4 : 4 channels conditioner for

inductive gauging probes

A 4 channels probe conditioner with analogue output


The CA4 is a compact conditioner module for half bridge (HBT) or LVDT probes. It is powered from the mains 24VDC


The zero and gain setting makes it compatible with most of the market's probes.

It is fitted with 4 analogue outputs from 0 to ±10 VDC and 0 to ±20 mA.


By mixing the zero and the gain (from 0 to 100%) and the full scale, it is possible to get a current output of 4-20mA or a voltage output from 0 to + 5VDC or 0 to + 10VDC





Main characteristics :


  • 4 independant channels
  • Current or voltage output
  • Inductive HBT or LVDT probe
  • Robust
  • DIN connectors
  • 24VDC power supply
