Three Tips for installation of sensor in extruder
1.Mount them correctly
Damage to a pressure transducer is commonly caused by its installation in an improperly machined hole. In forcing a transducer into a too-small or eccentric hole, the transducer diaphragm may be crushed and the instrument will not function.
Tool kits available for machining the mounting hole will help to make sure the holes are properly sized. A mounting torque of 100 to 200 in.-lb (for 1/2-20 UNF threads) is essential to form an adequate seal, but excessive mounting torque will cause seizing. To prevent seizing, apply a high-temperature anti-seize compound to the transducer threads prior to installation. Transducers installed at a mounting torque above 500 in.-lb will be difficult to remove even when anti-seize compound is applied.
2.Keep mounting holes clean
It is important to keep transducer mounting holes clean and free of any plastic build-up. Before an extruder is cleaned, all of the transducers should be removed from the barrel to avoid their being damaged. When they are removed, plastic is likely to flow into the mounting holes and harden. If this plastic residue is not removed, extensive sensor tip damage will result when the transducers are re-inserted.
A cleaning tool kit can be used to remove the plastic contamination. But note that repeated cleaning may produce “too deep” holes and result in damage to the transducer tip. If this occurs, spacers should be used to raise the transducer.
3. Clean with care
All the transducers should be removed before cleaning an extruder barrel with either a wire brush or special cleaning compounds. Either one of these can ruin the transducer’s diaphragm. The transducer should be removed while the barrel is hot and its tip wiped clean with a nonabrasive cloth. The transducer hole should be cleaned at the same time with a cleaning drill and guide sleeve.
