4.2.1.5 Process pipe connection
The process pipes can be mounted directly onto the process connections on the sensor. To
obtain a proper scaling, use a wrench on the base of the process connections as counter lock
to secure with the optimum torque.
4.2.1.6 Mounting a pressure guard
CAUTION
Avoid moisture, liquids or particles getting into the sensor enclosure
All sensors are filled with argon to avoid condensation. Penetration of humidity, liquids or
particles into the sensor may influence the measurement and in worst case affect the
measuring function.
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).
2. Carefully disconnect the nipple and mount the pressure guard. Use the enclosed spare part
sealing ring for proper sealing.
3. Make sure that the pressure guard does NOT touch any of the parts inside the sensor.
4. Check that the pressure guard has been correctively mounted and thoroughly tightened.
After dismantling the sealing ring must be replaced with a new sealing ring.
Pressure guards are not supplied with the sensor.
Before removing the nipple from the sensor enclosure, please note the following:
