| No. | Question & Answer |
|---|---|
| Q1 | Q: Which cold chain refrigeration units fit ZVEZDA 44-9298 speed sensor? A: Direct replacement for Thermo King HK450/SLX300/SLX400 cooling units, interchange OE 449298, passive magnetic design, long brass thread install without modifying gear housing. In stock, ship within 1–7 working days. |
| Q2 | Q: Refrigeration unit still randomly shuts down and cooling temperature fluctuates after replacement? A: Demagnetized magnet core or aging induction coil leads to weak pulse signal output, replace complete ZVEZDA integrated speed sensor to restore stable RPM sine wave signal and normal refrigeration performance. |
| Q3 | Q: Can this magnetic speed pickup replace engine MAP intake pressure sensor or coolant temperature sensor? A: Not interchangeable. This passive AC pulse rotation sensor detects gear rotation speed; MAP sensor is 5V active air pressure transducer, water temp sensor outputs NTC resistance signal, different power supply and signal generation principle. |
| Q4 | Q: Core advantages of ZVEZDA 44-9298 engine speed sensor? A: H-grade high temp pure copper induction coil, anti-demagnetization high coercivity permanent magnet core, long anti-corrosion golden brass thread body, FKM high temp refrigerant-proof O-ring sealing, thick black rubber terminal waterproof boot, OEM standard long thread size direct bolt replacement, neutral unbranded packaging, perfectly match Thermo King HK/SLX series refrigeration unit speed monitoring system. |
