WARNING!
In the final application, it must be ensured that the instrument,
even with medium temperatures > 70 °C, is not heated to over
70 °C.
When mounting the instrument, care should be taken that the
permissible operating temperature of the measuring instrument
is maintained, considering the effects of convection and thermal
radiation!
For this the instrument and the shut-off valve must be protected
by sufficiently long measuring lines or syphons.
The influence of temperature on the indication and measuring
accuracy must be observed.
The effective maximum surface temperature is not only
dependant upon these instruments, but mainly on the respective
medium temperature! With gaseous substances, the temperature
may increase as a result of compression warming.
In these cases it may be necessary to throttle the rate of change
of pressure or reduce the permissible medium temperature.
