 Model LD-DFA Capacitive level limit switch
Separate structure, easy to install
Against high temperature, high pressure, corrosion
Suitable for both solid and liquid media
No mechanical parts, free from service
Description
Model LD-DFA level limit switch is a newly developed measuring instrument. As Radio frequency and long**distance digital locating techniques were adopted., it solved two long existing problems: calibration and temperature drift. The innovative technique of long**distance digital locating will enlarge the application field of capacitive level limit switch in various industries
