RS-3000 Detection Unit

Quick Detection for variety of liquid. (NPN OUTPUT)

  • Quick Detection for variety of liquid, even low viscosity without absorbent paper.
  • By the featured double sensing devices, incorrect position of the sensor is alarmed.
  • Body fabricated by PFA, which allows use with most liquids and chemicals, and suitable for use in varied applications, particularly chemical blend and dispenser.

After leak detection, simple wipe the detection surface. Easier process than with detection tape or a liquid absorbing model.

  • Body and cable are protected by PFA.
  • Suitable for export equipment, CE marking, UL certified.
  • RS-3000C unit has DIN rail installation feature without auxiliary parts.
  • Easily viewable green LED signifies normal operations when red LED turns on, Liquid is detected and output is shut off.
