Some customers often inquire about the level sensor, I will share with you here. P+f Pepperl+Fuchs capacitive level sensor is suitable for industrial enterprises to measure and control the production process during the production process. It is mainly used for the long-distance continuous measurement and measurement of the liquid level of conductive and non-conductive media or the level of powder and granular solids. Instructions.

The capacitive liquid level sensor is composed of a capacitive sensor and an electronic module circuit. It is based on a two-wire 4-20mA constant current output. After conversion, it can be output in a three-wire or four-wire manner. The output signal is formed into 1 to 5V, 0～5V, 0～10mA and other standard signals. The capacitance sensor consists of an insulated electrode and a cylindrical metal container filled with a measuring medium. When the material level rises, because the dielectric constant of the non-conductive material is significantly lower than that of air, the capacitance changes with the height of the material. The module circuit of the sensor is composed of units such as reference source, pulse width modulation, conversion, constant current amplification, feedback and current limiting. The advantages of using the principle of pulse width modulation for measurement are low frequency, radio frequency interference to surrounding elements, good stability, good linearity, and no obvious temperature drift. The sensitivity of the sensor is directional. When the measured is a single vector, and its directivity requirements are high, the sensor with less sensitivity in other directions should be selected; if the measured is a multi-dimensional vector, the smaller the cross-sensitivity of the sensor, the better. okplazas.com p+F Pepperl+Fuchs sensor products, one-year warranty, one penalty ten for fakes!
