4.2 Installation instructions
Mounting of pressure guard
Moisture, liquids or particles getting into the sensor enclosure
All sensors are filled with argon to avoid condensation. Ingress of moisture, liquids or particles
into the sensor may influence the measurement and in worst case inhibit the measuring
function.
● Avoid moisture, liquids or particles getting into the sensor enclosure
Install a pressure guard as follows:
1. Place the sensor in a dry, clean place and leave it to acclimatize until it reaches ambient
temperature, preferred 20°C (68°F) with low humidity (at least below 50% RH).
2. Orient the sensor with the purge ports uppermost to minimize loss of the argon gas filling.
3. Carefully remove the plug and mount the pressure guard.
Use replacement soft metal sealing rings for proper sealing.
4. Make sure that the pressure guard does NOT touch any of the parts inside the sensor.
Maximum of 20 mm (0.79") insertion can be accommodated.
5. Check that the pressure guard has been correctly mounted and thoroughly tightened.

CAUTION
CAUTION
Lack of proper sealing
Soft metal sealing rings only maintain a hermetic seal within the enclosure with single use.
● Ensure that soft metal sealing rings are not reused.
WARNING
Operation in proximity with pressure guards
Prevent personal injuries by assuring that operation in close proximity with pressure
guards cannot take place.
