SR50A-316SS-L

The SR50A-316SS is a stainless-steel version of Campbell Scientific's acoustic sensor for measuring the distance from the sensor to a target. The stainless-steel chassis allows for operation in environments where corrosion is a concern (such as marine environments). It is typically used to measure snow or water depth, but it is well-suited for other uses.

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. This sensor is compatible with most Campbell Scientific data loggers.

The SR50A-316SS was designed to meet the stringent requirements of measuring depths and uses a multiple echo processing algorithm to help ensure measurement reliability.

SDI-12, RS-232, and RS-485 output options are available for measuring the SR50A-316SS. Campbell Scientific’s MD485 interface can be used to connect one or more SR50A-316SS sensors in RS-485 mode to an RS-232 device. This can be useful for sensors that require lead lengths that exceed the limits of either RS-232 or SDI-12 communications. The SR50AH is available with a heater option for locations where rime ice is a problem.

The SR50A replaced the SR50 in March 2007. The newer SR50A is smaller and has different output options than its predecessor.
