PR Electronics 6333A – 2-Wire Programmable Transmitter

Application

  • Measurement of temperature using Pt100…Pt1000 or Ni100…Ni1000 sensors with linearization.
  • Conversion of varying resistance from valves or Ohmic level sensors into a standard analog current signal.

Technical Specifications:

  • PR Electronics 6333A can be programmed by the user to measure temperatures across all RTD ranges specified by standards within seconds.
  • RTD and resistance inputs include cable compensation for 3-wire connections.
  • Ability to set a limit on the output signal.

Mounting/Installation:

  • Can be mounted vertically or horizontally on a DIN rail. Up to 84 channels per meter can be installed using the 2-channel version.
