Installation and Maintenance

Do not remove the protective cap until installation. Verify mounting hole machining and use an aluminum gasket.
Ensure no metal or plastic remains when removing transducers. Clean the diaphragm with a soft cloth.
Allow sufficient soak time for material at the transducer tip to melt before starting the process.
Keep the electrical housing below 80℃ to maintain accuracy and prolong transducer life.
Avoid prolonged overload pressure to prevent accuracy degradation.
Use shielded cables and ground the cable shield at one end to prevent interference.

Wiring Diagram
5PIN and 6PIN configurations are provided for connecting the transmitter to the system, with specific color codes for signal and calibration 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...
