Water temperature sensor shaft for swimming pool plumbing

Swimming pool water temperature monitoring needs a sensor whitch musnt be in contact with the water. Threfore you have to use a shaft, where you put sensor probe in. I made one for you. It has stadard outher thred G1/2 and also metric M18x1.5 for PG9 waterproof grommet at the end (optional). This sensor shaft shouldnt be inserted directly into pipe, but into intended drilling part, witch you can buy or print also - look into my other models.

Printing:

• print in vertical position
• meterial: PETG/ASA/ABS
• infill 10%
• no support

Sealing o-rings:

• 18x2.4 or 18x3.1 under the shaft head
• 16x2.4 for PG9

Before insertion of PG9 into the shaft put the nut out - use without the nut.
