1. Product Overview
The Induskey INK418 is a professional non-contact road-surface state measuring instrument utilizing high-precision imported laser sensors with spectral measurement technology. Unlike conventional sensors limited to snowfall below 1 cm, the INK418 measures snow and ice thickness over an extended range — up to 1,500 mm snow depth and 2.00 mm ice/water layer thickness — providing reliable data for road clearing and maintenance operations such as de-icing agent dosage calculation. The sensor mounts roadside at 2–15 m distance with no lane closure or road damage required, making installation faster and simpler than embedded alternatives. A built-in infrared thermometer simultaneously measures road surface temperature, while the friction coefficient output enables quantitative slipperiness assessment for traffic safety management.
2. System Architecture
The INK418 operates as a fully integrated remote sensing road condition unit with the following core components:
-
High-Precision Imported Laser Emitter: Directs a laser beam at the road surface for spectral analysis of reflected signals.
-
Spectral Analysis Receiver: Analyzes reflected laser energy to quantify water film, ice layer, and snow accumulation thickness.
-
Built-In Infrared Thermometer: Measures road surface temperature simultaneously with optical condition detection.
-
Signal Processing Unit: Calculates friction coefficient (0–1.00) from surface condition data for slipperiness assessment.
-
Controller & Data Interface: Manages configurable sampling intervals (1–60 min) and communication output.
-
IP65 Sealed Enclosure: Salt-fog and corrosion-resistant housing for coastal and harsh environments.
-
Power Module: DC 12V operation with <3W standby / 30W active power consumption.
