How to replace the depth module in an Area/Velocity sensor
Due to the presence of silt, large gravel and debris in channels, the depth sensor component of any
area/velocity sensor can be physically damaged through impact of large debris. To reduce costs and
downtime, MACE has developed a replaceable ceramic depth sensor, eliminating the need to replace the
entire A/V sensor. It is simply a matter of unscrewing the old sensor and replacing with a new one. An “o-ring”
seals the sensor electronics, and a locking ring holds the new sensor in position.
NOTE: For this procedure, you will need a MACE Replaceable ceramic installation
tool (850-481), and a MACE Replacement ceramic kit (850-410).
WARNING: This procedure should ONLY be carried out by MACE trained and
qualified staff in a clean and dry area.
WARNING: All sensor products must be clean and free of any potential biological
hazards. MACE recommends washing with microbicidal fluid.
Remove the damaged ceramic depth sensor
1. Place the clean and dry sensor on a flat workbench.
2. Find the " locating pins " on the base of the ceramic installation tool and the matching " apertures " on
the locking ring. Position the tool onto the locking ring.
