Greystone TNAP Temperature Sensor All Purpose Network

Greystone TNAP Temperature Sensor utilizes a precision sensor encapsulated in a 6 mm (0.236”) OD, 304 series stainless steel probe and is available in various lengths (see ordering chart). All probes provide excellent heat transfer, fast response and resistance to 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.

The duct type probes are installed through a hole in the side of the duct to monitor a single point temperature within the duct. Since the probes are tip sensitive, select a probe length that places the sensor well into the duct. Install the probe in a straight section of duct at a suitable distance downstream from any heating, cooling, or humidification devices.

PRODUCT DESCRIPTION

The all purpose single point network temperature sensor utilizes a precision sensor 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 resistance to 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 type probes are installed through a hole in the side of the duct to monitor a single point temperature within the duct. Since the probes are tip sensitive, select a probe length that places the sensor well into the duct. 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.

NOTE: For immersion applications, T2 series thermowell is required. When using a T1 series thermowell an adapter will be required (#0201001092).
