Simple float level sensor float type level sensor is replaced by a magnetic float float, sensor size, which is based on the Archimedes principle. Float level sensor is the use of tiny metal film strain sensing technology to measure liquid level, interface level, or density. It can be subjected to conventional scene keys to set operation at work. Hydrostatic level sensor or measurement sensor uses the principle of the hydrostatic pressure of work. It is generally used silicon pressure gauge sensors measured pressure into electrical signals, Xuzhou sensor, and then the amplifier circuit and compensation circuit compensation, and finally to 4 ~ 20mA or 0 ~ 10mA current mode output. Physical type sensor is the use by the occurrence of certain physical properties measured material properties made significant changes. Chemical sensor is the use of chemical substances can composition, concentration and other chemical quantity is converted to electrical quantities sensor made. Biological sensors is the use of a variety of biological or biological material characteristics made to detect and identify the chemical constituents in vivo sensors. Sensor which, Xinfeng (online consultation), Xuzhou sensor sensing provided by the Xinxiang City, Xinfeng purification technology Limited.
