Installation Instructions:

Do not remove the protective cap until ready to install. Verify correct machining of the mounting hole and install with an aluminum gasket.
Ensure no metal or plastic remains when removing the transducer. Clean the diaphragm with a soft cloth immediately after removal.
During start-up, bring the system to operating temperature and ensure sufficient soak time for any material at the transducer tip to melt before starting the process.
The transducer's tip can withstand high temperatures, but the shell should be kept at room temperature to maintain accuracy and longevity.
Avoid overloading the transducer beyond its rated pressure to prevent accuracy degradation and reduced lifespan.
Use shielded cable for wiring and attach the cable shield to ground at one end only to prevent jamming.

Wiring Diagram: The document provides detailed wiring diagrams for 5PIN and 6PIN configurations, specifying color codes for different output functions.

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...
