Input Level Sensor is a commonly used sensor for water level measurement. The input level sensor is suitable for water level measurement in petrochemical, water conservancy, electric power, pharmaceutical, water supply and drainage, environmental protection and other systems and industries. The input level sensor has excellent performance, anti-interference, small temperature drift, high stability, and the input level sensor has high measurement accuracy. The 4-20mA output of the input level sensor is highly anti-interference. Because the amplitude of the noise voltage in the industrial field may reach several V, but the power of the noise is very weak, so the noise current is usually less than nA level, so the 4-20mA transmission error to the input level sensor is very small; current source tends to infinity, wire resistance in series in the loop does not affect the accuracy, so in the ordinary twisted-pair cable can be transmitted hundreds of meters. And the upper limit of 20mA because of the explosion-proof requirements, 20mA current energized spark energy caused by the gas is not enough to ignite. 4~20mA current is commonly one of the most common standards. Since it is a standard, then when encountering such input level sensors to send signals to deal with these standard signals of the standard components, equipment, terminals are easy to buy, easy to support, but also easy to repair. Because these standardized input level sensors price is also very advantageous, and the standard common.
