I'm trying to find the best non-contact measuring technique (Eddy Current, Capacitive, Inductive, Optical…)
Can be used for measuring linear displacement or deviation of kiln-roller (of Carbon Steel material) with diameter between 1200 to 2000 mm and operate at 12 to 14 rpm.
Sensor of this type will be connected to DAQ device and PC as one of portable and multifunction measuring system.
Ambient temperature is high (could reach over 100°C in certain points) according to high temperature emitted from the kiln shell.
The following are required to be provided by our new measuring system:
Resolution of measurement better then 0.01 mm,
High operating temperature,
Measuring range of 20 - 25mm,
Compact size and portable system,
With output current or Volt, and working in
aggressive ambient conditions of high temperature and vibration.
Non-Contact displacement
