GREYSTONE HAS AN ISO 9001 REGISTERED QUALITY SYSTEM RIGID DUCT AVERAGE NETWORK TEMPERATURE SENSOR TNDR SERIES CABLE GLAND FITTING THREAD ADAPTER 1/2” NPT TO M16 ACCESSORIES - INCLUDED WITH E ENCLOSURE OPTION PRODUCT DESCRIPTION The multi point rigid duct average network temperature sensor incorporates numerous precision sensors at equal distances and encapsulated in a 6 mm (0.236”) OD, 304 series stainless steel probe and 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 rigid duct average type probes are installed in the side of the duct to monitor the average temperature within the duct. Select a probe length that allows the probe to span the duct width. Install the probe 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.

BACnet® COMMUNICATION BACnet® is a data communication protocol for building automation and control networks. The sensor communicates on a standard 2-wire RS-485 MS/TP network designed to run at speeds from 9600 to 115200 baud over twisted pair wiring. BACnet® is a registered trademark of ASHRAE. ASHRAE does not endorse, approve or test products for compliance with ASHRAE standards. Compliance of BACnet® listed products to the requirements of ASHRAE Standard 135 is the responsibility of BACnet® International (BI). BTL is a registered trademark of BI. MODBUS COMMUNICATION Modbus is a network protocol for industrial manufacturing environments. The sensor communicates on a standard Modbus network using the RTU (Remote Terminal Unit) transmission mode. The hardware interface is RS-485.
