Sensing Technology:
The INK440 utilizes the Pulsed Time-of-Flight (ToF) laser ranging principle. A Class 2 red laser diode emits a modulated beam towards the target surface. The sensor's high-sensitivity receiver captures the reflected light, and an embedded Digital Signal Processor (DSP) precisely calculates the distance based on the time delay between emission and reception. This advanced technology allows the sensor to bypass traditional optical limitations, delivering accurate, real-time distance data even on challenging low-light and high-reflectivity snow surfaces. Internal reference measurements further compensate for temperature drift and optical interference, ensuring long-term stability.
Self-Cleaning & Robust Design:
While a dedicated mechanical self-cleaning brush is not explicitly listed, the INK440 incorporates design features that serve an anti-fouling purpose. It features a durable glass optical window set within a rugged housing with IP65
protection (per IEC529 standard). This robust construction effectively resists environmental contaminants like snow, ice, and dust, minimizing maintenance requirements. The industrial-grade housing, available in white steel coating or plastic-coated finish, provides excellent corrosion and UV resistance, ensuring reliable performance in harsh winter environments. For extreme icing conditions, an optional de-icing heater is available, further enhancing its operational reliability and reducing the need for manual cleaning.
The versatility and reliability of the INK440 make it suitable for a wide range of applications across multiple industries:
