Permissible temperatures
Ambient: Model 232/262 -40 ... +60 °C
Model 233/263 -20 ... +60 °C (glycerine filling)
Medium: The permissible medium temperature not only depends on
the instrument design, but also on the ignition temperature
of the surrounding gases, vapours or dusts. Both aspects
have to be taken into account.
For maximum permissible medium temperatures see table 1.
Attention! In the case of gaseous substances, the temperature may
increase due to compression warming. In these cases it may be neces-
sary to throttle the rate of change of pressure or reduce the permissible
medium temperature.
