HDL604 anti corrosive 4-20ma acid level sensor adopts PTFE cable, which can measure strong acid and alkali liquids. The front-end protective cap protects the sensor diaphragm. It can also make the liquid contact diaphragm smoothly. The anti-corrosive wire is sealed with the outer shell. The ventilation pipe is connected with the outside inside of the cable, and the inner structure is designed to prevent condensation. The built-in micro signal processing circuit can be used for remote transmission. It has good stability and reliability. HDL604 series are widely used in liquid level measurement and control in environmental protection, water conservancy, frequency conversion water supply, industrial process control, chemical industry, and other fields.
Measured liquids: mainly measuring hydrochloric acid, sulfuric acid, nitric acid, hydrofluoric acid, sodium hydroxide, hydrogen peroxide, and other highly corrosive liquids, or chemical, electroplating wastewater, Seawater, etc .
