GREYSTONE HAS AN ISO 9001 REGISTERED QUALITY SYSTEM

ALL PURPOSE NETWORK TEMPERATURE SENSOR

TNAP SERIES

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).
