The liquid level sensor uses a magnetic float as the sensing element. The liquid level sensor reflects the measured liquid level or interface through the magnetic coupling between the magnetic float and the magnetic body in the display color column. Also known as magnetic level gauge, magnetic flip column level gauge, and magnetic float level gauge, it works using the principle of magnetic coupling, which makes up for the fact that glass tube level gauges cannot work under high temperature and high pressure and are fragile. A shortcoming.
The liquid level sensor has two installation methods: side-mounted and top-mounted. Either way can be bundled with a remote transmission device, so that the liquid level meter can display the liquid level locally and monitor the liquid level remotely. The bundled liquid level sensor It can be called a remote transmission liquid level sensor. The liquid level sensor indicator is installed outside or on the tank to indicate and control the liquid level in the tank. In the closed form, a drain valve can be installed as needed. The connecting flange can accept a control instrument for customizing the liquid level. The indicator is composed of a magnetic color chip. When the magnetic float ball in the body tube rises with the liquid level, the color chip flips over to display the liquid level. A magnetic switch or remote transmitter can also be installed on the main body tube to output switching signals or analog signals.
The liquid level sensor applies the connecting tube principle to ensure that the liquid level between the measured container and the measuring tube body is equal. When the float in the measuring tube changes equally with the measured liquid level, the magnetic body in the float and the color column displayed on the display board The magnetic body causes the color column to flip, white means no liquid, and red means there is liquid, so as to display the liquid level value on the spot. The liquid level sensor with local display has the advantages of intuitive and eye-catching display, wide viewing angle, compact and reasonable structure, safe and reliable, no "running, popping, dripping or leaking" phenomenon, small maintenance and low maintenance cost, and its indicating function does not require In addition to the power supply, even if the power supply fails, the liquid level observation will not be affected, making it an ideal liquid level detection instrument.
If the liquid level sensor is equipped with a UR-type resistance liquid level sensor, or a UB-type resistance-current liquid level transmitter and a (secondary) display instrument, it can complete electric remote transmission and output a standard of 4 to 20mA (or 0 to 10mA). signals to match recording instruments, or industrial control computer networking.
