Installation
Recommendation:
To facilitate sensor removal and installation, we suggest installing the socket in a location where
the liquid can be drained quickly and easily. By creating a one meter long piece of pipe (shown
below) with shut off valves at both ends, just a small volume of liquid needs to be drained to
enable sensor removal. Also, a precise sensor and socket installation can be performed in the
workshop, and this assembly can be placed in the production line with minimal down time.
4.3.3 The 32003 insertion/extraction valve
The ORBISPHERE 32003 insertion/extraction valve (illustrated below) allows for sensor
removal and installation without having to drain the fluid in the line. It can withstand a pressure
of up to 20 bars, with the sensor in place or not.
Sensor insertion is made by inserting the sensor into the housing and tightening the retaining
collar until it stops. As the retaining collar is tightened, the valve will open to allow the sample to
flow past the sensor head. Remove the sensor by unscrewing the collar and pulling the sensor
out. As the collar is unscrewed, the valve will automatically close to avoid any sample spillage.
The diagram above right, shows the sensor in a sample line with the valve open allowing the
sample to run past the sensor head.
