see the title of this article, we learned to know the difference between the radar and ultrasonic thermometer thermometer must know both principle, because the principle of the two appears to be the same, but the precise measurement object is different. Let's first look at the principle of magnetic flap wUd | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer thermometer:

radar low extremely short microwave pulse energy is emitted by transmitting and receiving antenna system. Radar wave are running at the speed of light. Running time can be transformed into material level signal by electronic parts. A special time extension method can guarantee the stability of a very short period of time and accurate measurements of wUd magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer:

ultrasonic thermometer by ultrasonic transducer ( The probe) A high frequency pulse waves encountered measured level ( Material) Surface is reflected back to the echo are converted to electrical signals received by transducer wUd magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

from the above two principles we can see the following two points difference wUd magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

1, radar emission of thermometer is electromagnetic wave, wave velocity and the environment, such as temperature, smoke, pressure has nothing to do, even in a vacuum, propagation speed is always the speed of light.

2, ultrasonic launch is ultrasonic thermometer, belongs to the mechanical wave, like waves, its propagation velocity is closely related to the state of the media. Ultrasonic thermometer is used in the measurement of liquid level for the steel atmospheric vessels, probe temperature measuring element, the wave velocity can be temperature compensation, because the cause of the material, the use of a very wide temperature range is not relatively.

from the above 2 difference between thermometer can summarize the following 2 points applied conclusions: more than 1, ultrasound was applied to the flow measurement, radar applied in level measurement; 2, said the launch of radar wave from the energy is greater than ultrasonic energy, electromagnetic wave better than mechanical wave transmission distance and speed, but electromagnetic waves are susceptible to electromagnetic interference, material attenuation mechanical wave is easy to suffer indignities, so its application is the ultrasonic must be open place for cleaner air of gas phase detection. Radar in comparison with a little gas phase can be sealed in the volatile, but the things in the gas phase is the most ideal situation atmosphere, or maintenance quantity will increase wUd magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer
