GREYSTONE HAS AN ISO 9001 REGISTERED QUALITY SYSTEM

HIGH ACCURACY FLEXIBLE CABLE DUCT AVERAGE TEMPERATURE SENSOR

HATSDF SERIES

NOTE: The sensor accuracies listed in the specifications section apply to the sensing element only prior to

product assembly and may not be reflected in the complete assembly.

Due to the measurement uncertainty, it is possible, that the true resistance value of the single delivered

sensor at 0°C can be out of the defined tolerance class. Profiling each assembly to take into consideration

lead wire and the attachment method should be completed.

PRODUCT DESCRIPTION

The high accuracy flexible multi-point duct

temperature sensor utilizes several precision

sensors spaced at equal distances. The probe

is FT-6 plenum rated cable and is available in

various lengths (see ordering chart). 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.
