GREYSTONE HAS AN ISO 9001 REGISTERED QUALITY SYSTEM REMOTE PROBE STRAP-ON NETWORK TEMPERATURE SENSOR TNRP SERIES PRODUCT DESCRIPTION The single point remote probe network temperature sensor incorporates a precision sensor encapsulated in a 6 mm (0.236”) OD, 304 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. For best results, thermal conductive compound should be applied to pipe prior to mounting the probe. Find a suitable location along the pipe where both the probe and remote enclosure can be mounted. If necessary, remove a section of insulation from pipe. Position probe directly on the pipe and secure using a pipe clamp. For added security, make 1 to 3 loops of the sensor cable around the pipe and feed through wire hole on the enclosure and secure using the supplied grommet. If applicable, the pipe insulation can be re-applied to the pipe over the probe.
