Non contact liquid level sensor online shopping with drurylandetheatre.com? The Liquid Level Controller is attached to the outside of the tank. Non-contact detection of tank liquid level. Liquid Level Controller supports liquid level alarm, fault alarm, and 485, Modbus, 4-20mA, FoundationFieldBus, PROFIBUS or Hart. Liquid Level Controller is installed outside the tank. The HS-ULC-Pro Liquid Level Controller works based on the principle of ultrasonic waves, and is also called “externally attached liquid level switch. It is mainly used to detect the liquid level of the storage tank, and its sensor (digital probe) acts on the outer wall of the storage tank. It supports upper and lower limit alarms, tanks Body temperature display or monitor whether there is liquid in the pipeline. Liquid Level Controller is suitable for liquid level process control in the pharmaceutical, petroleum, chemical, electric power and other industries.
The advantages of ultrasonic liquid level gauge are very outstanding. It is mainly reflected in the following aspects : Safe and clean. The instrument has long service life. The measurement is stable and reliable with high precision. Of course, the ultrasonic liquid level gauge also has its own limitations and insurmountable defects. Specifically, it is mainly manifested in: Ultrasonic liquid level gauge is greatly affected by dust. This is because although the dust environment has little effect on the speed of sound, it has a very significant effect on the attenuation of sound waves. Therefore, it is best not to use an ultrasonic level gauge in the presence of dust.
Ultrasonic Level Sensing measures liquid levels based on the principle of ultrasound. When ultrasonic waves encounter a high-density medium while propagating in a low-density medium, they cannot penetrate the high-density medium. There will be reflections at the interface of the two media. The ultrasonic liquid level gauge is made using this feature. Read even more information on ultrasonic water level sensor.
The External Ultrasonic Tank Level Sensor adopts the sonar echo ranging principle. It overcomes the influence of the tank wall on the transmission of ultrasonic signals. It adopts advanced digital signal processing technology. It can truly realize non-contact, high-precision measurement of the liquid level in the tank. The External Ultrasonic Tank Level Sensor can output 4-20mA standard signals or output the measurement results to the upper computer (or secondary meter) through the RS-485 interface. It can meet the automatic control of the system.
What is ultrasonic level sensor? Ultrasonic level sensor is a monitoring instrument for measuring liquid height, tank height, and material position. The ultrasonic level sensor can adopt two-wire, three-wire or four-wire technology. The two-wire system is: power supply and signal output are shared. The three-wire system is: the power supply circuit and the signal output circuit are independent. When using DC 24v power supply, a 3-core cable can be used, and the negative terminal of the power supply and the negative terminal of the signal output share a core wire. The four-wire system is: when using AC 220v power supply, or when using DC 24v power supply. When the power supply loop and the signal output loop are required to be completely isolated. A 4-core cable should be used. Find more info at here.
