FLEXIBLE CABLE DUCT AVERAGE TEMPERATURE SENSOR

TSDF SERIES

CABLE GLAND FITTING

THREAD ADAPTER 1/2” NPT TO M16

ACCESSORIES - INCLUDED WITH E ENCLOSURE OPTION

PRODUCT DESCRIPTION

The flexible multi-point duct average temperature

sensor utilizes several precision sensors spaced at

equal distances. The probe is FT-6 rated plenum

cable and is available in various lengths. All probes

are constructed to provide excellent heat transfer

and a fast response.

TYPICAL INSTALLATION

For complete installation and wiring details,

please refer to the product installation

instructions.

The flex-duct average probes are installed through

a hole in the side of the duct to monitor an average

temperature within the duct. Select a probe length

that allows for criss-crossing the duct multiple

times. Install the probes in a straight section of

duct at a suitable distance downstream from any

heating, cooling, or humidification devices. The

cable probe needs to be fastened onto hangers

using tube clamps or wire ties and should be

secured every 100 cm or 3’ maximum to prevent

movement of the wire and prevent wear. If

sensor is to be used in high velocity or vibration

environment use of rigid style duct probe is

recommended.

The enclosure provides mounting tabs for ease of

installation.
