sampling circuit of liquid.
• Remove the sensor cable connected at the sensor end.
• Hold the sensor body in one hand to avoid rotation, and unscrew the collar with the other
hand.
• Pull the sensor straight out of the socket or flow chamber.
• Install sensor storage cap and sensor base (to protect the connection).

3.9.5 Weld-on stainless steel socket

The ORBISPHERE 29501 weld-on sensor socket can be used to install a sensor into a stainless
steel pipe (min.Ø 50 mm or 2"). When welding the socket to the pipe, check that setback
between the pipe's inner diameter and the sensor tip does not exceed 4 mm (see diagram).
Note: Be sure to remove the two O-rings from the socket before welding and leave the sensor's stainless
steel cap screwed on during welding to prevent thread distortion.
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 (refer to
Figure
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.
