The SL300 ultrasonic snow depth sensor provides a total system in a compact package, containing an ultra sensitive electrostatic transducer and the supporting circuitry to provide a 0 to +5 or 0 to +2.5 VDC output with fully independent zero and span adjustments over the entire operating range of detection from 1.5’ – 32’.

The piezoelectric crystal inside the transducer converts electrical pulses into sound energy that travels in the form of a wave at the established frequency and at a constant speed in a given medium.

The ultrasound waves are emitted in bursts and received back at the transducer as echoes. The instrument measures the time for the bursts to travel down to the reflecting surface and return. This time will be proportional to the distance from the transducer to the surface and can be used to determine the level of water or snow.

The speed of sound through the medium (air) varies with the medium’s temperature. SL300 contains a temperature sensor to compensate for changes in operating temperature that would alter the speed of sound and hence the distance calculation that determines an accurate level measurement.

The sensor is designed to work in the extreme conditions where the measurement of snow depth is likely to be required. The unit is mounted facing down to the ground before any snow falls to determine the sensor to ground height, then as snow falls the sensor measures the rise and fall in surface height.
