Dongfeng GX truck parts Tire pressure sensor assembly 3637510-TH770

Equipped with a high-sensitivity MEMS (Micro-Electro-Mechanical Systems) pressure sensor, this assembly delivers accurate real-time data to the Dongfeng GX’s dashboard. It monitors tire pressure within a range of 0–800 kPa (116 psi)—covering the truck’s standard operating pressure (380–450 kPa for heavy-duty tires)—with an accuracy of ±2 kPa. Additionally, it tracks tire temperature (from -40°C to 125°C) with a precision of ±2°C, alerting the driver to overheating (a major cause of tire blowouts in heavy loads or high-speed driving). The sensor updates data every 3 seconds when the truck is in motion and every 60 seconds when stationary, ensuring the driver receives timely warnings of pressure drops (≥10% below set value) or temperature spikes (≥85°C), critical for preventing tire damage and accidents

Built to withstand the harsh conditions of truck tire operation (vibration, impact, road salt, and moisture), the sensor features a rugged construction. The outer housing is made of high-impact PBT (polybutylene terephthalate) plastic with glass fiber reinforcement (30% GF), resisting cracking from wheel impacts or debris. The sensor’s internal circuit board is coated with a conformal epoxy layer that protects against water, dust, and corrosion (IP6K9K waterproof rating), ensuring functionality even after prolonged exposure to rain, mud, or road salt. The valve stem is crafted from nickel-plated brass, preventing rust and ensuring airtight sealing for over 50,000 km. Rigorous testing confirms the sensor endures 100,000+ vibration cycles (10–2,000 Hz) and impacts up to 500 G, meeting the durability requirements of commercial truck tires

The sensor uses a high-performance RF (radio frequency) module optimized for Dongfeng GX’s TPMS, ensuring stable data transmission to the vehicle’s on-board receiver. It maintains a communication range of up to 15 meters (even with metal wheel rims blocking signals) and reduces interference from other vehicle electronics (e.g., GPS, radio) via frequency hopping technology. To extend battery life, the sensor adopts an ultra-low-power design: it enters sleep mode when the truck is stationary (sending data only once per minute) and wakes automatically when motion is detected. Powered by a replaceable lithium-ion battery (CR2450, 3V), it provides continuous operation for 3–5 years (or 100,000 km), eliminating frequent battery replacements and reducing maintenance costs for fleet operators

Engineered for efficient replacement in tire shops or fleet yards, the sensor simplifies installation with user-friendly features. It includes a pre-installed valve stem and a torque wrench adapter that ensures proper mounting (recommended torque: 5–7 N·m), preventing over-tightening that could damage the sensor or wheel rim. The sensor is compatible with Dongfeng GX’s tire rotation and replacement processes—no re-calibration is needed when moving the sensor between wheels (as long as the vehicle’s TPMS is reset via the dashboard). To ensure safety, the assembly complies with international TPMS standards (e.g., ISO 15031-6, FMVSS 138), meeting the regulatory requirements for commercial trucks. It also includes a 24-month warranty against manufacturing defects (e.g., signal failure, battery leakage, or housing cracking), providing Dongfeng GX truck owners with reliable tire monitoring and long-term peace of mind
