1 Scope
This standard specifies the structural type, connecting mode, basic parameters, model, technical requirements, test methods, inspection rules, mark, packing and storage of the contact-type level controller and the radio frequency level controller for the electrostatic precipitator.
This standard is applicable to the contact-type level controller and radio frequency admittance level controller for quantitative discharging of the ash hopper of the self-controlled electrostatic precipitator.
This standard is also applicable to other mechanical level control switches, rotary level controller and capacitive material-level controller.
