measuring instrument  capacitive liquid water level sensor

 

Description:

It can convert all kinds of level, changes in the level of medium parameters into a standard current signal, remote to operate the control room for the secondary instrument or centralized computer device display, alarm or automatic control. Its good structure and installation method, suitable for high temperature, high pressure, highly corrosive, easy to crystallize, anti-clogging, level, level anti-cold junction under special conditions and solid powder, granular materials, etc., continuously measuring level of , widely used in electric power, metallurgy, chemical, food, pharmaceutical and other industries and sewage treatment, boiler drum, coal and other places of the package level, level and physical level measurement.
