Installation and Maintenance
1. Ensure correct machining of the mounting hole before installation. Use an aluminum gasket and secure the electronics housing with the provided bracket.
2. Remove transducers only when the polymer is molten and clean the diaphragm with a soft cloth.
3. Allow sufficient soak time for the transducer tip to reach operating temperature before starting the process.
4. Keep the electrical housing at room temperature to maintain accuracy and prolong the transducer's life.
5. Avoid prolonged overload pressure to prevent accuracy degradation.
6. Use shielded cables and ground the cable shield at one end to prevent interference.
