Melt Pressure Sensor Tip Cleaning
If the Melt Pressure Sensor is removed from the barrel while it is still hot, the tip can be carefully cleaned with a clean soft cloth.

Hole Cleaning
Mounting holes should always be cleaned before installation. Any burr or hardened polymer material can damage the diaphragm during assembly.
As the inner extruder barrel wears, it can reduce the size of the converter bore. We offer cleaning kits for 1/2 ”-20UNF and M18x1.5 converter holes. Using a cleaning kit ensures that each hole is properly sized.
Check Tip Stagnation Before Repositioning
As the extruder chamber wears, the converter tip will move closer and closer to the inner barrel wall. If the extruder is allowed to be flush with the inner barrel wall, it will wear at the same rate as the inner wall. MPS recommends maintaining a minimum of 0.02 ”stagnation. Copper shims can be made to push the tip away from the inner wall.
Keep Probes Dry
Do not allow oil or water to come into contact with the transducer or cables.
