EJXC40A Digital Remote Sensor (DRS)

EJXC40A Digital Remote Sensor (DRS) Transmitter connects two pressure sensors, master (high pressure side) and slave (low pressure side) in a remote location, with dedicated electrical cable to measure differential pressure.
EJXC40A is suitable to measure liquid, gas, or steam flow as well as liquid level, density and pressure and outputs a 4 to 20 mA DC signal corresponding to the measured differential pressure.

Key Features

  • High performance, high accuracy and high reliability
    Better performance over long capillaries of diaphragm seal system.
  • Suitable for level measurement of a tall tank
    DRS cable length (maximum): 45 m
  • Signal characterization for various tank types

Digital Remote Sensor (DRS) can provide the solutions of ...

  • No limitation of higher tank height
  • Stable tank level measurement with minimized temperature effect
  • Single Sensor Accuracy:
    • 0.055% of span
    • 0.025% of span (for EJX630 screwed mount/HAC)

Wide Range Differential Pressure Measurement

  • Screwed types: up to 50MPa
    • Up to 70MPa (for EJX630-Dcapsule screwed mount)
  • Flange types: up to flange rating

Digital Remote Sensor (DRS) is connecting two transmitters electrically,
so it’s not influenced by solar radiation and temperature change.
