The SR50 is a rugged, acoustic distance sensor that is manufactured by Campbell Scientific (Canada) Corp. It measures the elapsed time between emission and return of an ultrasonic pulse. This measurement can be used to determine snow or water depth. An air temperature measurement is required to correct for variations of the speed of sound in air. The SR50 was designed to meet the stringent requirements of measuring depths and uses a multiple echo processing algorithm to help ensure measurement reliability.In order to allow triggering of the SR-50 sonic ranger by the Babuc ABC datalogger, as well as to input the digital readout of the snow level, we designed and built a custom digital interface suitable for low temperatures operation. This was necessary since the Babuc ABC is only equipped with a proprietary serial interface for which specifications were not readily available. Furthermore, voltage levels, pulse length and rise times which can be output from the Babuc ABC’s actuator sockets are neither compatible with the Campbell SR-50 nor programmable, at least within the required tolerances. These parameters also showed to be very sensitive both to battery voltage and to ambient temperature, which is normal when considering their intended purpose of supplying power to external devices.Our interface allowed to correctly shape the trigger pulse for initiate the snow level measurement, as well as to acquire the serial pulse train output from the SR-50 through a spare datalogger input meant for rain gauge connection.
Features:
-Emits acoustic pulse and measures travel time; air temperature measurement required
- Measurement range 0.5 to 10 m (1.6 to 32.8 ft)
- Accuracy ±1.0 cm (±0.4 in) or ±0.4% of distance to target whichever is greater
- Measures water level or snow depth
- Manufactured by Campbell Scientific (Canada) Corp.
