No. Description Function
1. Protection cap cover
Plastic cover that slides over the pressure sensor. It clamps onto the
protection cap sensor holder.
2. Pressure sensor Electrical transmitter that translates a pressure measurement into a
readable 4…20mA signal over a 2 wire connection.
3. Rubber ring Rubber ring that seals leakage from air and water between the pressor
sensor and protection cap of the sensor.
4. Protection cap sensor holder Plastic isolated holder with tubing that holds the pressure sensor. The
sensor holder functions as additional protection against heat and moisture.
It also allows the pressure sensor to be easily exchanged.
5. Threaded end of sensor cap 1/2” threaded end through which the protection cap is fitted onto the
buffertank.
6. Welded threaded socket
1/2” Socket that is welded onto the buffertank and in which the pressure
sensor protection cap is fitted. (fitted by a third party company)
2.7 Pressure sensor with tracing ribbon
For cold environments it is possible to install tracing ribbon around the sensor to prevent it from freezing. Although the
protection cap of the sensor can protect the sensor against freezing to a certain level, the additional tracing ribbon is an
optional feature that is advisable for environments with long periods of frost.
