Installation and Maintenance:

Ensure correct machining of the mounting hole before installation. Use an aluminum gasket and secure the electronics housing with the provided bracket.
Remove transducers only when the polymer is molten and clean the diaphragm with a soft cloth.
During start-up, ensure the system reaches operating temperature and follow zero and span adjustment procedures.
Keep the transducer shell at room temperature to maintain accuracy and prolong life.
Avoid overloading the transducer beyond its rated pressure to prevent accuracy degradation.
Use shielded cables for wiring and ground the cable shield at one end to prevent interference.

Wiring Diagram: The document provides detailed wiring instructions for both 5PIN and 6PIN configurations, specifying color codes for signal and excitation connections.

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...
