Submersible Level TransmitterPerformance characteristics

Submersible Level Gauge CBM-2100 CBM-2700 Submersible Level Gauge (Liquid Level Gauge/Liquid Level Transmitter/Liquid Level Sensor/Water Level Sensor) is a pressure sensor used to measure liquid level. The input liquid level gauge (pressure gauge) is based on the principle that the static pressure of the measured fluid is proportional to the height of the liquid. It uses advanced foreign isolated diffusion silicon sensing elements or sensitive ceramic capacitive pressure sensors to convert the static pressure into an electrical signal. After temperature compensation and linear correction, it is converted into a standard electrical signal (usually 4 ~ 20 ma / 1 ~ 5 VDC). Cbm-2100cbm-2700 series hydrostatic 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 it is user-friendly. Standard signal output modes such as 4 ~ 20mA, 0 ~ 5V, 0 ~ 10mA 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 liquid surface depth can be obtained. The input liquid level meter has good stability, full scale, and long-term zero stability, up to 0.1%FS/year. Within the compensation temperature range of 0 ~ 70°C, the temperature drift is less than 0.1% FS, and within the entire allowable operating temperature range, the temperature drift is less than 0.3% FS.

The input-type liquid level meter is equipped with reverse protection and current-limiting protection circuits. When the positive and negative polarities are reversed during installation, the transmitter will not be damaged. If there is an abnormality, the transmitter will automatically limit the current to within 35MA.

The input liquid level gauge has a solid structure, no moving parts, high reliability and long service life. The input liquid level meter is easy to install, has a simple structure, is economical and durable.
