Mechanical design

The duct temperature sensor consists of the following components:

· Two-sectional plastic housing comprised of base with connection terminals and re-

movable cover (snap-on design)

· Fully active, flexible probe with sensing element which acquires the average temper-

ature

The connection terminals can be accessed after removing the cover. Cable entry is

made via a grommet which, if required, can be replaced by a cable entry gland M16

(IP 54).

After fitting the mounting flange, the sensor can be installed in 6 different immersion

positions so that the sensor housing is always located outside the insulation for layers

up to 70 mm. The probe with a length of 2 or 6 m is to be fitted across the air duct with

the help of the mounting clamps supplied with the sensor.
