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 immediately after removal.
  3. Allow sufficient soak time to ensure material at the transducer tip is molten 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 and reduced lifespan.
  6. Use shielded cables and ground the cable shield at one end to prevent interference.

Operating instruction Attention for installation 1, Installation Do not remove protective cap until ready to install. Prior to initial installation, verify correct machining of mounting hole. Install with aluminum gasket. The electronics housing should be secured, with the enclosed mounting bracket. 2, Remove Make sure that there is no remained metal or plastic; remove all of the transducers from the equipment before you clean the extruder. You can remove the transducer only when the polymer is molten. And clean the diaphragm of the transducer with soft cloth as soon as you remove it. At the...
