GREYSTONE HAS AN ISO 9001 REGISTERED QUALITY SYSTEM FLEXIBLE COPPER NETWORK DUCT AVERAGE TEMPERATURE SENSOR TNDC SERIES PRODUCT DESCRIPTION The multi point duct average network temperature sensor incorporates numerous precision sensors at equal distances encapsulated in a 7.94 mm (0.3125”) OD, soft copper probe that is available in various lengths. All probes provide excellent heat transfer, fast response and resist moisture penetration. The transmitter provides a BACnet® or Modbus signal for network connection. A compact ABS enclosure with a hinged and gasketed cover is provided for ease of installation. TYPICAL INSTALLATION For complete installation and wiring details, please refer to the product installation instructions. The duct average probes are installed through a hole in the side of the duct to monitor an average temperature within the duct. Select a probe length that allows for criss-crossing the duct multiple times. Install the probes in a straight section of duct at a suitable distance downstream from any heating, cooling, or humidification devices. The enclosure provides mounting tabs for ease of installation.
