APOLLO Cross Slope Sensor 157449/04-21-20020 Electrical System Asphalt Paver Parts

Product Overview
 
The Cross Slope Sensor (Part Numbers: 157449 / 04-21-20020) is a high-precision electronic component engineered specifically for the electrical system of asphalt pavers, serving as the core of automatic slope control during pavement construction. Designed to meet the rigorous demands of road building, this sensor accurately detects the transverse inclination angle of the paver screed in real time, converting mechanical slope changes into stable electrical signals for the paver's control unit. By enabling precise adjustment of the screed's lateral height, it ensures uniform pavement cross slope (e.g., 0-6% adjustable range) and flatness, eliminating manual measurement errors and guaranteeing compliance with road construction standards (ASTM E1155, EN 13108). As a direct OEM-compatible replacement part, it features seamless fitment with leading asphalt paver models, maintaining the original electrical interface and installation dimensions for hassle-free integration.
 
Key Features & Technical Advantages

Ultra-High Measurement Precision: Equipped with a MEMS (Micro-Electro-Mechanical Systems) accelerometer and digital signal processing (DSP) chip, the sensor achieves a measurement accuracy of ±0.02° and resolution of 0.001°, ensuring reliable slope detection even under high vibration (≤10g) and dynamic operating conditions. The built-in temperature compensation module (-40℃ to +85℃) minimizes drift caused by ambient temperature changes, maintaining stability over long working hours.

Robust & Weather-Resistant Design: Housed in a die-cast aluminum alloy shell with IP67 ingress protection rating, the sensor is fully sealed against dust, water spray, and asphalt residues. The corrosion-resistant coating (passivation + powder coating) and shock-absorbing rubber gasket enhance durability, enabling a service life of 10,000+ working hours in harsh construction environments.

Stable Signal Transmission: Adopts dual-output signal modes (4-20mA analog signal + RS485 digital signal) for compatibility with different paver control systems, ensuring low-noise and anti-interference transmission over long distances (up to 100m). The signal response time is ≤5ms, enabling real-time feedback and rapid adjustment of the screed, preventing slope deviations during paver movement.

Easy Installation & Calibration: Features a universal mounting bracket with adjustable angles and standardized bolt holes, allowing direct installation on the paver's screed or frame without modifying the existing electrical system. The one-button calibration function (via external calibration port or control unit) simplifies setup, reducing installation time by 50% compared to conventional sensors.

Comprehensive Safety Protection: Integrated with overvoltage protection (10-30V DC wide voltage input), reverse polarity protection, and short-circuit protection, preventing damage from electrical faults in the paver's electrical system. Complies with international electrical standards (IEC 61010-1, CE) for safe and reliable operation.
