Product catalog summary

Description
The TNU Ultrasonic Snow Level Sensor is designed to measure snow levels up to 4 or 8 meters, depending on the model (TNU04 or TNU08). It operates by emitting ultrasonic pulses towards the snow surface and receiving the reflected waves. The sensor includes a self-correction feature for temperature variations, ensuring accurate measurements by adjusting for changes in air density. The device is equipped with a protective, self-ventilated solar shading to safeguard the transducer and maintain accurate air temperature readings.

Main Features

Sound electronic filtering
Compact and affordable design
Self-correction for air temperature compensation
Equipped with self-ventilated solar shading

Technical Specifications

Measurement Performance:
Distance range for TNU04 is 0.6 to 4 meters, and for TNU08 is 0.8 to 8 meters. The accuracy is ±1 cm with a resolution of 0.5 cm and a beam width of 12° ± 2°.
Operating Conditions:
Temperature range is -20°C to +65°C, and humidity range is 0% to 100%.
Outputs:
Both models provide RS485-Modbus outputs for temperature and snow level. Tension and current outputs vary with the model.
Power Supply and Consumption:
Voltage supply is 10 to 16 Vdc. Consumption varies by output type, with peak capsule piloting power at 14.4 W.
Mechanical Specifications:
The protective body is made of ABS plastic, aluminum, and stainless steel screws. The TNU04 weighs 1.6 kg with dimensions of Ø 210 mm and height 323 mm, while the TNU08 weighs 2.3 kg with a height of 390 mm. Both have IP67 electrical connections.

Ordering Codes

CARATTERISTICHE PRINCIPALI TNU sensors capture snow level up to either 4 or 8 meters, according to the model in use (TNU04, TNU08). Functioning system is related to the emission of short ultrasonic frequency pulses towards the depth of snow to investigate and to the subsequent reception of the reflected wave, generated once the pulses reach the surface the snow is lying on. It ensures excellent performance for what concerns accuracy, thanks to a system of self-correction of the level measurement. Indeed, by means of an integrated temperature sensor, it can easily take into account the variation...
