The on-line monitoring of the electrostatic field strength in fluidized bed granulation and drying using a newly developed electrostatic field detecting system

摘要

An electrostatic field detecting system comprised of an electrostatic field sensor, a signal conditioning system, and an air purge unit was newly developed to continuously monitor the electrostatic field strength of charged particles in fluidized bed granulation and drying. The output characteristics of the sensor and the operating characterisitcs of the system, such as sensitivity and linearity, were tested.
