External level switch online shopping by Drurylandetheatre
Top liquid level controller online store? 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 : The structure is simple. The reading is convenient. It is very easy to install and maintain. Of course, the ultrasonic liquid level gauge also has its own limitations and insurmountable defects. Specifically, it is mainly manifested in: There is a blind spot in the ultrasonic liquid level measurement. The dead zone is the area where the meter cannot measure. During the transmission of ultrasonic pulses, a small area near the ultrasonic transducer usually cannot receive sound waves. The blind zone where sound waves cannot be received is related to the measurement distance of ultrasonic waves. Generally speaking, the smaller the measurement distance, the smaller the blind zone. The larger the measurement distance, the larger the blind zone.
In the measurement, the ultrasonic pulse is emitted by the sensor (transducer), and the sound wave is reflected by the liquid surface and then received by the same sensor or ultrasonic receiver. Through piezoelectric crystal or magnetostrictive device into electrical signals. The distance between the sensor and the measured liquid surface is calculated by the time between the transmission and reception of sound waves.

Infrared online debugging function : Applicable to occasions where it is not suitable to open the cover for testing in dangerous situations. At the same time, it reduces the difficulty of debugging. Self-diagnosis function : It has its own working status diagnosis function. It also has hardware diagnosis function. It enhances the reliability and stability of the level gauge. One-key recovery function : When the external measuring level gauge works abnormally, it can be restored to the normal state with one key through the debugger. Local display and remote transmission function : The level gauge can not only display the level value on the spot in time. But also remotely transmit it to the control room through the signal line.
The pulse will propagate in the container wall and liquid, and will be reflected by the inner surface of the container. By detecting and calculating the characteristics of the reflected signal, it can be judged whether the liquid level has reached the position where the controller is installed. The liquid level controller can output a relay signal to facilitate the detection and control of the liquid level. The float level switch is a kind of level switch. The float level switch uses magnetic force to operate. No mechanical connections. The operation is simple and reliable. When the float switch floats the measured medium, the float moves the main body. At the same time, the magnet on the other end of the float will control the magnet on the switch action lever.
