ILK-M - DUCT AIR QUALITY TRANSMITTER/CONTROLLER

Description: ILK-M transmitters are specifically engineered for detecting and controlling levels of Volatile Organic Compounds (VOC), temperature, and humidity within ventilation ducts. Utilizing MEMS sensing technology, these transmitters ensure accurate and durable measurement of VOC levels, which are closely related to CO2 levels. With the VOC level information provided, effective demand-based ventilation control can be implemented. The VOC sensor is capable of detecting a wide variety of hydrocarbons, including cigarette smoke, exhaled breath, solvent vapors, emissions from building materials, and cleaning agent vapors. These transmitters can be seamlessly integrated into systems supporting Modbus RTU protocol via RS-485 connection, requiring the ML-SER tool for Modbus settings during commissioning.

Features:

  • Detection and control of VOC levels, temperature, and humidity within ventilation ducts.
  • Accurate and durable VOC measurement related to CO2 levels.
  • Demand-based ventilation control based on VOC level information.
  • Wide detection range for various hydrocarbons.
  • Compatible with systems supporting Modbus RTU protocol.
  • N model display with scrolling measurement values and the option to lock the desired value for continuous viewing.
  • Control output based on either a single measurement value or the maximum selection of all values.
  • Equipped with an optional HD-R relay (24 Vac, 1 A) for additional control output.
