Ultrasonic liquid level sensor suitable for low temperature environment measurement

The level measurement of cryogenic liquid is a relatively technical job, because the low temperature differential pressure transmitter is difficult to measure the liquid level of the medium below minus 20 degrees, and the low temperature differential pressure transmitter itself also has a range on the range. Limitations, there is also a characteristic difference between the media, so it requires more technical content to measure the level of cryogenic liquids, and if you want to measure the level of cryogenic liquids, the indirect measurement method is of course a very suitable choice. In the case of liquid, it is the safest and most effective. Now I will introduce an ultrasonic liquid level sensor ToughSonic-30 suitable for liquid level measurement in low temperature environment.

Working principle of ultrasonic liquid level sensor

When the ultrasonic liquid level sensor is working, the high-frequency pulse sound wave is emitted by the transducer (probe), and it is reflected on the surface of the measured object (water surface), and the reflected echo is received by the same transducer (probe) and converted into an electrical signal . The time between pulse sending and receiving (the movement time of the sound wave) is proportional to the distance from the transducer to the surface of the object. The relationship between the distance s of sound wave transmission and the speed of sound c and the transmission time t can be expressed by the formula: s=ct /2

Acoustic wave is a kind of media that transmits information. It is closely related to mechanical vibration. The mechanical vibration generated by the impact and movement of an object can spread outward in the form of waves. According to the frequency of the wave generated by the vibration, it is divided into audible sound waves, infrasound waves and ultrasonic waves. The sound waves higher than 20khz are called ultrasonic waves.

Therefore, the ultrasonic sensor is a sensor developed by using the characteristics of ultrasonic waves. It has the advantages of accurate measurement, wide detection range, flexible use, and easy maintenance. For liquid level measurement in low temperature environments, the detection distance of the American SENIX ultrasonic liquid level sensor-ToughSonic-30 provided by Gongcai.com is 30 feet (9.1 meters). Like all ToughSonic sensors, it is durable and easy to use in harsh industrial environments. It is completely immersed, corrosion-resistant, impact-resistant, and tough across the board. It can also be fully configured with SenixVIEW software. The sensor has a 1.5-inch (38.1 mm) housing with 1.5-inch NPT threads on each end and a smooth middle section for various mounting options. The sensor has a 9-core cable that allows up to six simultaneous serial, analog and/or switch outputs. These main force sensors are used in remote monitoring and harsh factory environments all over the world.
