The original factory calibration curve is matched with the rooftop unit-specific controller, significantly reducing the frequency of false alarm low-pressure protection shutdowns.

The FKM composite fluororubber seal maintains stable elasticity under long-term refrigerant oil immersion, slow aging, and low expansion rate conditions.

The pre-assembled shielded wiring harness effectively isolates the electromagnetic interference generated by the built-in fan and compressor.

The IP64 protection level is suitable for outdoor rooftop environments with high temperatures, rain, and strong vibrations.

During maintenance, it can be directly plugged out and replaced, and no professional calibration is required after installation.
