SR50AT-316SS-L Stainless-Steel Sonic Distance Sensor for Marine Environments with Temperature Sensor
Services Available
Repair Yes
Free Support Yes

Overview

The SR50AT-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 (that is, marine). It is typically used to measure snow depth, but it is well-suited for other uses.

The SR50AT-316SS includes an external temperature sensor and outputs a temperature-corrected distance reading, eliminating the need for further post-processing.  This sensor is compatible with most Campbell Scientific data loggers.

Detailed Description

The SR50AT-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 SR50AT-316SS. Campbell Scientific’s MD485 interface can be used to connect one or more SR50AT-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 SR50ATH-L 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.

Data Logger Considerations

One single-ended channel per probe is required; an excitation channel can be shared by several probes.
