Product Specification
ART Infrared Refrigerant Transmitter Description
The ART gas detector is a state-of-the-art, fixed, non-dispersive infrared refrigerant transmitter used to detect a wide range of refrigerant gases. The fast-responding sensor accurately detects refrigerant gas leaks without cross interference from other gases. It can be used as a stand alone system or integrated into a building management system (BMS).
The ART can be connected to a gas detection system using analog output wiring or Modbus® network communications wiring. It is compatible with the QCC Quad Channel controller and the FCS Flexible Control System controller as either an anlog or digital transmitter.
ART Infrared Refrigerant Transmitter Key Features
• Long life, non-dispersive infrared refrigerant sensor allows for accurate, low level leak detection with no cross interferences from other gases
