HDL604 anticorrosive liquid level transmitter 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 anticorrosive 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. 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.
