Submersible liquid level gauge CBM-2100 CBM-2700 submersible liquid level gauge (liquid level gauge/liquid level transmitter/liquid level sensor/water level sensor) is a pressure sensor used to measure liquid level. The drop-in liquid level gauge (pressure gauge) is based on the principle of the static pressure of the measured fluid, which is proportional to the height of the liquid.

Performance characteristics of the input liquid level gauge

Submersible liquid level gauge CBM-2100 CBM-2700 submersible liquid level gauge (liquid level gauge/liquid level transmitter/liquid level sensor/water level sensor) is a pressure sensor used to measure liquid level. The drop-in liquid level gauge (pressure gauge) is based on the principle of the static pressure of the measured fluid, which is proportional to the height of the liquid. It uses foreign advanced isolated and diffused silicon sensing elements or sensitive ceramic capacitive pressure sensors to convert the static pressure into electrical signals. After temperature compensation and linearity correction, it is converted into a standard electrical signal (usually 4 ~ 20 ma / 1 ~ 5 VDC). Cbm-2100cbm-2700 series static pressure liquid level gauge (liquid level gauge) is suitable for liquid level measurement of various media in petrochemical, metallurgy, electric power, pharmaceutical, water supply and drainage, environmental protection and other systems and industries. The structure is exquisite, the adjustment is simple, the installation is flexible, and the user is convenient to use. 4 ~ 20mA, 0 ~ 5V, 0 ~ 10mA and other standard signal output methods can be selected according to user needs. At the same time, the liquid pressure is introduced into the positive pressure chamber of the sensor through the air guide stainless steel, and then the atmospheric pressure Po on the liquid surface is connected to the negative pressure chamber of the sensor to offset the Po on the back of the sensor, so that the pressure measured by the sensor is: ρ.g.h. Obviously, by measuring the pressure P, the depth of the liquid surface can be obtained. The input liquid level gauge has good stability, full scale, long-term zero stability, up to 0.1% FS/year. The temperature drift is less than 0.1%FS in the compensation temperature range of 0 ~ 70℃, and the temperature drift is less than 0.3%FS in the entire allowable operating temperature range.

The submersible liquid level gauge is equipped with reverse protection and current limiting protection circuit. The transmitter will not be damaged when the positive and negative polarities are reversed. The abnormal transmitter will automatically limit the current within 35MA.
