The drop-in liquid level transmitter is a pressure sensor that measures liquid level. Based on the principle that the measured hydrostatic pressure is proportional to the height of the liquid. Adopt high-purity imported single crystal silicon sensitive components or ceramic capacitor pressure sensitive sensors. Convert static pressure into electrical signal. After temperature compensation and linear correction. Converted into a standard electrical signal. The level sensor is generally suitable for liquid level measurement of various media in petrochemical, metallurgical, electric power, pharmaceutical, water supply and drainage, environmental protection and other systems and industries.
The input type liquid level transmitter is based on the principle that the measured liquid static pressure is proportional to the height of the liquid, and uses the piezoresistive effect of high-purity imported single crystal silicon sensor or ceramic sensor to convert the static pressure into an electrical signal. After temperature compensation and linearity correction. Converted into 4-20mADC standard current signal output. The sensor part of the throw-in liquid level transmitter can be directly thrown into the liquid, and the transmitter part can be fixed with a flange or a bracket, which is extremely convenient to install and use.
The input type liquid level transmitter is directly input into the measured medium, which is quite convenient to install and use. Solid structure, no moving parts. Measurement, not affected by bubbling and deposition of the measured medium. Wide-range temperature compensation. The input type liquid level transmitter has power reverse polarity protection and overload current limiting protection. At the same time, the pressure of the liquid is introduced into the positive pressure cavity of the sensor through the gas-conducting stainless steel. Then the atmospheric pressure Po on the liquid surface is connected to the negative pressure cavity of the sensor to offset the Po on the back of the sensor, so that the pressure measured by the sensor is ρ.gH Obviously, by measuring the pressure P, the liquid level depth can be obtained.
