Radar Water Level Sensor working principle
Micro-power microwave pulses are emitted from the radar antenna and travel through space at the speed of light. It is reflected by the object to be measured and received by the radar.
The time difference between the transmission and reception of the pulse signal is proportional to the distance from the radar antenna to the measured object. The propagation speed of electromagnetic signals in space is the speed of light. Usually when measuring the distance, the time difference between the transmitted pulse and the received pulse is very short and only on the order of nanoseconds.
Conventional technology is difficult to accurately measure this time.
SIRD-908 Radar Water Level Sensor uses an advanced equivalent sampling method to accurately measure the original nanosecond time interval. So as to realize the accurate measurement of distance.
The extremely tiny 26GHz radar signal is emitted in the form of short pulses from the antenna end of the radar level gauge.
The radar pulse is reflected by the sensor environment and the surface of the object and received by the antenna as a radar echo.
The rotation period of the radar pulse from emission to reception is proportional to the distance, that is, the level.
The antenna receives the reflected microwave pulse and transmits it to the electronic circuit. The microprocessor processes this signal. Identify the echo generated by the microwave pulse on the surface of the material.
The correct echo signal identification is completed by intelligent software, and the accuracy can reach millimeter level. The distance D from the surface of the material is proportional to the time travel T of the pulse:
Where C is the distance of the empty tank at the speed of light E is known, then the distance of the level L is: L=E-D
It is set by entering the empty tank height E (=zero point), the full tank height F (=full scale) and some application parameters. Application parameters will automatically adapt the meter to the measurement environment. Corresponds to 4-20mA output.
