DOTX-45 Dissolved Oxygen System Part 5 – Sensor Assembly

Figure 5-2 Submersible Sensing Module Assembly

Follow the procedure below to prepare the D.O. sensor module for operation:

1. Unscrew the electrolyte chamber from the assembled sensor and also

remove the vent screw from the side of the sensor body.

2. Remove the front nut from the bottom of the chamber and discard the

protective membrane. O-rings are contained in grooves on both the bottom

and top of the chamber. Be sure that these o-rings remain in place.

3. From the package of membranes supplied with the sensor, place a new

membrane into the front nut, holding the membrane by its edge to avoid

fingerprint oil from contaminating the membrane. The membrane is clear

and is separated from other membranes by a light blue paper spacer.

4. Screw the front nut on to the chamber until you feel the o-ring compress.

Hand tight compression is all that is needed. Do not use tools to tighten. The

membrane should be flat across the bottom of the chamber without wrinkles.

5. Fill the chamber with electrolyte until the level reaches the bottom of the

internal threads.
