CHINO WORKS, LTD. has recently commercialized an infrared absorption type moisture meter utilizing three wavelengths to meet a longtime demand for measuring coal moisture with high accuracy in an on-line system.
It is applicable to coals whose particles are less than 3mm diameter in grain size when digged out coal was crushed into particles by a crusher. Its major specifications are as designated below.
Moisture measuring range: 2-12% H2O
Measuring distance: 300mm
Accuracy: About ± 0.5% H2O in case of the surface moisture when the measuring diameter is 50mmφ.
Since the calibration curve differs according to brands, it should be previously stored into the computer before starting the moisture measurement.
