A Hand
Held Instrument for Fast Accurate Measurement of Moisture Content
in Solid Materials.
The James Instruments Moisture Master utilizes the latest electronic
technology to measure the quantity of water within its sensing field.
The unit has two modes of operation the pin mode, and search mode.
In the pin mode, two pins are pushed into the material and a high
frequency field is created between these two pins. In the search mode
the unit uses a high frequency capacitive sensor to sample a large
volume of the material, instantaneously. Changes in this electromagnetic
field are directly proportional to the dielectric constant of the
material through which it passes. As the dielectric constant of water
is almost two orders of magnitude greater than most non-metallic materials,
variations in this parameter can be correlated to the moisture content.
After extensive testing of various materials, relationships between
the change in this field and moisture content have been determined.
These relationships have been digitized and implemented using the
latest in micro-computer technology, thereby allowing the user the
direct readout of moisture content for concrete, masonry, hard wood,
soft wood, gypsum, and brick. The pin method has been found to be
most effective in low density materials such as fir wood or pine wood.
The search mode has been found to be most effective for higher density
materials such as brick, masonry, gypsum and concrete. |
