Sensor đo mực nước bằng siêu âm SR50A-L

Mã sản phẩm : 1489837455

The SR50A is a rugged acoustic sensor for measuring the distance from the sensor to a target. It is typically used to measure snow or water depth, but it is well-suited for other uses. Because the speed of sound in air varies with temperature, an independent temperature measurement is required to compensate the distance reading. A simple calculation is applied to initial readings for this purpose. Note: Campbell Scientific recommends model SR50A-316SS-L for marine environments.

    Benefits and Features Wide operating temperature range User-selectable options for output Compatible with most Campbell Scientific dataloggers Optional heater available (3W @ 12VDC or 12VAC) Detailed Description The SR50A 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. Campbell Scientific’s MD485 interface can be used to connect one or more SR50A 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 SR50A replaced the SR50 in March 2007. The newer SR50A is smaller and has different output options than its predecessor. The SR50AH is available with a heater option for locations where rime ice is a problem.   Specifications General Measurement Time
