GREYSTONE HAS AN ISO 9001 REGISTERED QUALITY SYSTEM STRAP-ON NETWORK TEMPERATURE TRANSMITTER TNSO SERIES CABLE GLAND FITTING THREAD ADAPTER 1/2” NPT TO M16 PRODUCT DESCRIPTION The single point strap-on network temperature sensor incorporates a precision sensor is encapsulated in a 38.1 mm x 12.7 mm (1.5” x 0.5”) machined aluminum heat sink. A 25.4 cm (10”) S/S pipe clamp is provided to secure the assembly to various sizes of pipes. All probes are constructed to provide excellent heat transfer, fast response and are potted to 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 strap-on temperature transmitter series can be mounted directly to various sizes of pipes and secured using a 254 mm (10”) S/S pipe clamp. The 254 mm (10”) S/S pipe clamp is a “Quick Release” type and can be separated by moving the tightening screw. Postion the aluminum plate on the pipe so it makes the best contact, wrap the clamp around the pipe and re-assemble and tighten. For best results, thermal conductive compound should be applied to pipe prior to mounting the probe. Wiring connections are made inside the enclosure.

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.
