Remote Laser Particle Sensor

Description

Models 3718-A / 3719-A

2-Channel Remote Particle Sensors for Facility Monitoring Applications

Kanomax particle sensors with analog output are designed to fit into existing monitoring systems or to be used as a stand-alone unit for monitoring critical areas when connected to an alarm or controller.

The sensors are available with both 0.1 CFM and 1.0 CFM flow rates, and in two particle size ranges:

  • 0.3 µm / 0.5 µm
  • 0.5 µm / 5.0 µm

Key Advantages

  • 2-channel particle sensor with Modbus communication via RS485 interface
  • Flexible 4–20 mA analog output (available on 1.0 CFM unit only)
  • Available in 0.1 CFM and 1.0 CFM flow rates
  • Outputs particle counts, error status, and alarm signals
  • Can be connected to PLCs or data loggers for facility monitoring
  • Suitable for integration into process or building automation systems
  • Fully compliant with ISO 21501-4 and JIS B9921 standards
  • Configuration software included for easy parameter setup
  • Power supply via network connection or AC adapter
  • Stainless steel housing
  • 3-year warranty

Applications

  • Facility Particle Monitoring
  • Hospital Surgical Rooms
  • Cleanroom Monitoring
  • Building Monitoring Systems
