Immersion temperature sensor QAE2164.010
Equipment combinat
ions
All systems or devices that are capable of acquiring and handling the sensor’s
DC 0...10 V or 4...20 mA output signal.
Function
The immersion temperature sensor acquires the temperature of the medium via its
sensing element whose resistance value changes as a function of the temperature.
This change is converted to a DC 0...10 V or 4...20 mA output signal, depending on the
type of sensor. The output signal corresponds to the selected temperature range.

Mechanical design
The immersion temperature sensor consists of housing, printed circuit board,
connection terminals and immersion rod.
The 2-sectional housing is comprised of base and removable cover (snap-on design).
The measuring circuit and the setting element are located on the printed circuit board
inside the cover, the connection terminals on the base.
Cable entry is made via the M16 cable entry gland (IP54) supplied with the sensor
which can be screwed into the housing. Immersion rod and housing are rigidly
connected.

The setting element is located inside the cover. It consists of 6 pins and a shorting plug.
It is used to select the required measuring range and to activate the test function.
The different plug positions have the following meaning:
