Since compensation and computing - over the years in sensor engineering and technical personnel has been developed for the temperature drift and non-linear sensor output to compensate for the large amount of work the sensor characteristics, but did not solve the problem fundamentally. The self-compensating and computing capabilities of smart sensors for temperature drift and non-linear compensation sensor opens up new roads. Thus, the relaxation sensor sensor precision machining requirements, as long as the sensor can guarantee good reproducibility of the test signal using a microprocessor calculated by the software, using multiple fitting and difference calculation method to compensate for drift and non-linear wireless sensor , so that it can obtain more accurate results pressure sensor. Simple float level sensor float type level sensor is replaced by a magnetic float float, 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, and then the amplifier circuit and compensation circuit compensation, and finally to 4 ~ 20mA or 0 ~ 10mA current mode output.
