PORTABLE ELECTRONIC MOISTURE METER

 

PORTABLE ELECTRONIC MOISTURE METER is designed primarily as production line tool for measuring the moisture content of paper roll in motion on  the paper machine.  Rugged, Stainless Steel Roller sensing electrode permit instantaneous, on line or spot check non –destructive moisture measurement, on the fastest paper machine as well as measurement on stationary rolls or stack of paper.  It is highly versatile instrument  and has ability to handle a variety of moisture problems in paper industry. 

 

                                     

FEATURE

 

*   Roller Electrode pair has a Radio Frequency Field, which cover an area 12” x 16” & 2” deep are the responsible to detect the average moisture content or of moisture distribution throughout the sample.  Radio frequency capacitance circuit minimizes effects of pH and temperature variations. 

 

*   Multi-purpose dial for Direct Reading Percentage Scale, Numerical Reading Scale or Comparative Testing Scale. 

 

*   “High-Medium -Low” sensitivity switch enables testing of various products in various moisture ranges 0 – 35%. 

 

*   Powered by two standard ‘C’ size 1.5 volts alkaline batteries.  Build in standard for quick calibrations.  No technical skills needed to operate. 

 

PRINCIPLE OF OPERATION

 

PORTABLE ELECTRONIC MOISTURE METER is designed to measure the moisture via the capacitance measurement principle.  A capacitance (Dielectric Constant) measurement technique was chosen because of its stability in the presence of changing paper temperatures and pH.  The instrument actually acts as a capacitor where is one of the capacitor plates is roller and other plate is aluminium case of the instrument. 

 

A radio frequency field is generated at both rollers, then penetrates the paper roll or stacks to a depth of approx. 5 cm.  The RF field then returns to the case of the instrument and complete the path of travel.  When water is present in paper, then the paper dielectric constant is increased in proportion to the moisture content and calibrated into % moisture content directly.
