  • Easy to use
  • Provides compact localised display


Providing a local display for a multitude of applications, the PM1000 series is a 4 digit LED plug-on display for use with transmitters with 4-20 mA 2 wire output and fitted with DIN43650 connector. It fits simply between the transmitter plug and connecting cable socket and is powered from the 4-20 mA current loop signal of the transmitter. No additional power source is required.

Display settings are stored in non-volatile EEPROM, and can be easily modified through the menu using two programming buttons. Set-up parameters (zero, span, decimal point position, filter, and set-point level) can all be reprogrammed and stored and retained when power is removed. The display assembly inside the enclosure can be rotated through 90° steps, which will suit any mounting angle and simple installation.

For use with ESI models:

GS4200; HP1003; HP1103; LP1003; PR3100; PR3110; PR3200; PR3850; PR3860

Typical applications include:

  • Local readout on pressure, temperature, level, RH, or flow transmitters
  • Alarm activation or control

Adaptations for custom connectors can be made and available on request. Please contact the sales team.
