Product Description
The Combi Well is used in combination with a pointer ther-
mometer and serves for remote indication of the measured
value. The temperature sensor (3) of a pointer thermometer
is installed into the Combi Well; so the temperature value is
displayed locally by the pointer thermometer. For remote in-
dication an electric or electronic indicator is connected to the
Pt100 measuring resistor (4) in the Combi Well. The Combi
Well can be supplied with an analog output signal 4...20mA
instead of a Pt100.

Pointer Thermometer
The Combi Well is combined with different types of ther-
mometers and electric indicators. Installation and service
according to their own manuals.
ATTENTION
Measuring instruments are sensitive. So all parts should
be protected from being dropped and from knocks.
Notice max. ambient temperature 80°C.
3.
Mounting
The combi well is designed for installation in a thermometer
pocket to EN 50 216 (formerly DIN 42 554). The thermometer
pocket must be fi lled at least 2/3 with oil. To install, unsrew
the lower nut G1"(2) of the Combi Well and screw it into the
thermometer pocket.
IMPORTANT
Never apply force to the combi well, always slacken the
double screwed connection for realignment.
Insert the Combi Well and ensure correct alignment. Tighten
the double screwed connection. Unscrew the cover. Insert
the cable from the remote display through the cable gland
M20×1,5. Connect it to the terminals (Pt100) as shown
under Fig.2 and 3. Make sure to use the right „wire circuit"
for your display. Insert the temperature sensor (approx.
50 cm) through the hole in the casing (M20×1,5) and push
fully home (approx. 210 mm) into the immersion tube of the
Combi Well. Pull through the capillary line, route it without
kinks and fi x it. Tighten up the cable glands. Screw the cover.
4.
Testing
Check the indication of the pointer thermometer and the re-
mote display after a warm up of 30 minutes. Both indicators
should be in the individual tolerance.
