These thermometers correspond to the EN 13190, DIN 43772 and DIN 16179. The user must
ensure that the appropriate thermometers with regard to the medium effect on the used
material/measuring system, scale range and version is selected .. The optimum selection of the
scale range of the thermometers is given, if the operating pressure is in the midscale of the
scale range.
The temperature measuring points should be prepared according to the indications for tapped
holes. Further information you will find on the VDE/VDI directives 3511 and 3512 page 2.
Sealing washers according to DIN 7603A are particularly suitable. The correct torque depends on
material and shape of the sealing washer. It should not exceed 80 Nm.
Torque should never be applied to the case. Instead, an adjustable wrench should always be used
on the wrench flats of temperature gauge socket to tighten or remove the thermometers.
Thermometers without glycerin/oil filling should be installed such as to avoid exposure to vibration
and to allow easy observation of the dial indication.
We recommend the installation of appropriate thermowells between temperature tapping point
and thermometer facilitating replacement of the thermometer or a zero point control while the
system is pressurised .
The thermometers should be installed such as to avoid that the admissible ambient temperature
(ambient and medium) and possibly convection and heat radiation will not exceed the temperature
span the thermometer is intended for.
Normal gauge position will have the facia dial in its vertical position. Positions other than vertical
will be indicated by a symbol on the dial.
To avoid damages the temperature measuring gauge is stored in its original packing.
Storage temperature -40 to +70°C.
