Siem ens Immersion temperature sensors QAE21 CE1N1781en
Building Technologies 2018-05-28
Characteristic Accuracy
R Resistance value in Ohm
J Temperature in degrees Celsius
DJ Temperature differential in Kelvin
Mechanical design
The immersion temperature sensors consist of the following components:
· Two-sectional plastic housing comprised of base with connection terminals and re-
movable cover (snap-on design)
· Immersion rod complete with sensing element
The connection terminals can be accessed after removing the cover. The cable entry is
via a grommet which, if required, can be replaced by a cable entry gland M16 (IP54).

Engineering notes
Protection pockets made of Brass may not be used with nominal pressures over PN 10
or at temperatures over 130° C. For higher nominal pressures or temperatures up to
max. 135 °C the protection pocker is to omit (max. PN 16) or a protection pocket made
of stainless steel (V4A) is required (see table accessories).
The max. media temperature for the QAE2130.xx is 125 °C!
