The Asphalt Paver Grade Sensor, available in models G176M, D900624802, and 14276729, is a high-precision positioning component designed for a wide range of asphalt pavers—including popular models from Caterpillar, Volvo, and Vogele. Manufactured by JST, this sensor plays a critical role in “grade control” systems, measuring the paver’s elevation relative to a reference (e.g., a string line, laser, or existing road surface) and sending real-time data to the paver’s controller. This ensures the asphalt is laid at the exact thickness specified (e.g., 50mm for highway overlays), eliminating uneven surfaces and reducing material waste. It is engineered to meet international standards (ISO 9001) and is compatible with both new and retrofitted grade control systems.
Grade control is make-or-break for paving projects, and traditional sensors often fail in challenging conditions. This sensor addresses key pain points:
• Low Visibility: Fog, rain, or night paving can disrupt optical sensors (e.g., laser-based systems), leading to incorrect elevation readings. The G176M/D900624802/14276729 sensor uses ultrasonic + infrared dual technology, maintaining accuracy (±0.1mm) even in low-visibility or dusty environments.
• Reference Surface Irregularities: When paving over uneven existing roads (e.g., pothole repairs), sensors may misinterpret bumps as elevation changes. This sensor’s adjustable “filtering mode” ignores small irregularities (≤5mm), ensuring the paver follows the overall grade—not temporary bumps.
• High-Speed Paving: Highway projects often require pavers to operate at 5–8 meters per minute. Slow-response sensors cause delays in elevation adjustments, leading to thickness variations. This sensor has a response time of ≤10ms, ensuring real-time adjustments even at maximum paving speeds.
• Dual-Technology Sensing: Combines ultrasonic (for long-range detection, up to 2 meters) and infrared (for short-range precision, 0–500mm) technologies, ensuring accuracy across all paving scenarios.
• High Precision: Offers a measurement accuracy of ±0.1mm and a resolution of 0.01mm, exceeding industry standards for asphalt paving (typically ±0.5mm).
• Robust Design: Housed in a corrosion-resistant aluminum alloy casing (IP68 rating), protecting against water submersion (up to 1 meter for 30 minutes), dust, and asphalt splatters. The sensor head is coated with a Teflon-like material to prevent asphalt buildup.
• Easy Calibration: Features a one-button calibration function and a digital display, allowing operators to calibrate the sensor in 2–3 minutes—no specialized tools or training required.
• Measurement Range: 0.1–2000mm (ultrasonic mode); 0.01–500mm (infrared mode).
• Electrical Specifications: Operating voltage: 12–24V DC; Output signals: RS485 (digital) + 4–20mA (analog); Current consumption: ≤20mA.
• Mounting Options: Includes a universal mounting bracket (compatible with 10–15mm diameter poles) and adjustable angle (0–90°), enabling installation on the paver’s screed or side frame.
• Environmental Ratings: Operating temperature: -30°C to 85°C; Shock resistance: 50G (1ms); Vibration resistance: 10G (10–2000Hz).
• Compatibility Check: Provides a free compatibility tool—customers input their paver model and grade control system (e.g., Topcon, Leica), and JST confirms the correct sensor model (G176M/D900624802/14276729) within 12 hours.
• Calibration Support: Offers a remote calibration service—technicians guide operators via video call to ensure accurate setup, critical for projects with strict thickness requirements (e.g., airport runways).
• Warranty & Replacement: Backed by a 24-month warranty. If the sensor fails, JST ships a replacement within 48 hours for urgent projects, with no cost for shipping or installation support.
• Training Materials: Includes a detailed user manual, calibration video, and troubleshooting guide (available in English, Spanish, and German) to help operators maximize sensor performance.
