SNOW DRIFT SENSOR SND

  • Maintenance-free & special design to resist the highest winds, extreme temperatures, rime, sunlight, abrasion, ashes and even temporary submersion.
  • Lightweight, corrosion free, UV/Ozone stable, non-obstructable. Resistant to shock, vibration, lightning, corrosion, humidity, animals, insects and splashes. Operating temperature from −40 °C to 80 °C (−50 °C to 100 °C extended).
  • Very low power consumption: 2.1 mA continuous for nominal operation (10% duty-cycle) or 21 mA for continuous operation.
  • Adaptable to any structure thanks to a range of high standard stainless steel clamping accessories.
  • Directly connect the sensor to your central unit or configure any analog or digital communication through the included USB dongle.
  • Compatible with almost any external analog or digital central unit, with a very long extension cable (typ. up to 200 m), with IoT (LPWAN) transceivers and industrial control systems (BMS, SCADA, etc.).

Description

EXTREMELY ROBUST SENSOR TO DETERMINE SNOW DRIFT INTENSITY

The sensing part of the instrument is a cylindrical, anti-abrasion, anti-adhesion and anti-rime coated tube supported by two strong stainless steel arms. The impact of drifting snow and the friction of laminar wind induce a change in internal acoustic pressure. The excitation by snow and wind is discriminated by a specific acoustic, mechanical and electronic design.

It features continuous or pulse analog voltage outputs and supports SDI-12 communication, serial RS-232, and Modbus RTU RS485 (using an optional adapter). The full configuration of the sensor can be customized at any time with a Plug-and-Play PC connection or remotely, using serial commands.
