Campbell Scientific is adding several new versions of the SR50A sonic ranging sensor to our product line. We will offer models that include:
- An external air temperature sensor
- A stainless-steel chassis, which allows the sensor to be used in marine or other corrosive environments
- A heater that prevents ice from coating the transducer
The SR50A-series sonic ranging sensors provide a non-contact method for determining snow or water depth. They determine depth by emitting an ultrasonic pulse and then measuring the elapsed time between the emission and return of the pulse. Since the speed of sound in air varies with temperature, an independent temperature measurement is required to compensate the reading. The SR50A-series sensors meet the stringent requirements of measuring depths, and use a multiple-echo-processing algorithm to help ensure measurement reliability. The new models promise to be valuable new additions to our snow and water depth sensors.
