RE572409 Temp Sensor for John Deere 4045HLV71 4045HLV72 Engine Systems


Engine Coolant Temperature Monitoring
The RE572409 Temp Sensor employs nickel-chromium thermocouple technology with magnesium oxide insulation for -40°C to 250°C operational precision. AISI 316L stainless steel construction resists glycol-based coolant corrosion and mineral deposits. Integrated SAE J1587 protocol ensures real-time data communication with engine control modules. Triaxial vibration dampening maintains stability under 25G mechanical stress (20-2000Hz frequency range). Thermal drift compensation prevents measurement errors during rapid load changes. Seven-layer epoxy coating achieves IP69K protection against high-pressure washdowns. Automatic cold junction calibration maintains ±0.8% accuracy across thermal cycles. Standard 3/8"NPT threading enables direct installation in coolant passages. Continuous circuit monitoring detects sensor fatigue and connector oxidation. Electropolished surface treatment prevents scale buildup in hard water environments. Dual-range output configuration supports both analog dash displays and digital control systems.
