DOs and DON'Ts
1. General Recommendations
1.1. Operating temperature limits
(pressure sensing element)
Bronze bellows:
-20 to +60°C
Stainless steel bellows:
-20 to +150°C
Stainless steel tube:
-20 to +150°C
NBR diaphragm:
-20 to +100°C
EP diaphragm:
-40 to +120°C
FKM diaphragm:
0 to +150°C
/!\
For temperature switches, refer to the range tables.

1.2. Ambient operating temperature limits
(housing)
-20 to 70°C (except temperature switches from the C, G and M ranges: max.55°C) - others on request.
1.3. Radiant heat
Avoid installing the instrument near (radiant) heat sources. Observe the ambient operating temperature limit.
1.4. Pulsations
A suitable shock mount or flexible piping connection must be provided to protect bellows instruments in case of
vibrations or process instability (possible use of PA-type pressure switches).
1.5. Steam
A siphon must be placed upstream from the pressure switches on a steam circuit to limit the temperature
at the sensor.
1.6. Condensation
Protect from excessive sunlight to limit the effects of night-time condensation. The installation location must be chosen
very carefully in seaside locations or damp environments.
1.7. Vibrations
Georgin recommend avoid mounting the instrument directly on vibrating equipment.
Otherwise, an effective anti-vibration system, fully suitable for installation (assembly type, process connection,
electrical connection, ...) and its environment, must be chosen.Flexible piping connections and silent blocks may
sometimes be necessary.
The effectiveness of this mounting must be checked after installation.
