A moisture content tester for non-destructive multipurpose, which may be arranged on an apparatus that needs to be proceeded with moisture content test for proceeding a testing job of water containment on the objects to be tested, and which is carried out in a single machine and has a material-handling apparatus that may remove the material after being tested therefrom, and which is characterized in that:
- the moisture content tester is at least comprised of:
- a shell body, in which there is an accommodation space;
- a circuit plate, which is accommodated in the accommodation space, and on which is at least arranged with a design of circuit that may proceed temperature sensing, generate high frequency wave, and receive high frequency wave;
- a temperature compensation temperature-sensing bar, of which one end is connected to the circuit plate and another end is protruded out the shell body and may proceed the sensing of temperature value;
- at least an emitting pole-plate, of which one end is connected onto the circuit plate and protruded out the shell body through one side of the shell body, and which is coupled to the circuit capable of generating high frequency wave to make the high frequency wave be emitted from the emitting pole-plate;
- at least a receiving pole-plate, which is protruded out the shell body and kept an appropriate distance with the emitting pole-plate, and which is coupled to the circuit capable of receiving high frequency wave to make the high frequency wave emitted from the emitting pole-plate be received by the receiving pole-plate and the high frequency wave received by the circuit is converted into high frequency signals;
- and
- a controlling unit, which is coupled to the circuit plate, and the high frequency signals received by the receiving pole-plate and temperature value sensed by the temperature compensation temperature-sensing bar are all transferred to the controlling unit through the circuit plate, and the corresponding value of water containment can be calculated out by the controlling unit according to the high frequency signals and in matching with the temperature value;
- wherein,
- the emitting pole-plate is shown as a fin-shaped structure, of which upper side has an inclining side;
- one side of the shell body is shown as an opening shape and is an opening side, through which the circuit plate is made to be set into the accommodation space, and the receiving pole-plate is shown as a covering plate shape, which may just be covered on the opening side of the shell body, and on the receiving pole-plate, there is arranged with an opening and at least a fin, and the position and form of the opening is matched with the receiving pole-plate to provide it to protrude through the receiving pole-plate, and the extension direction of protrusion of the fin is matched with the receiving pole-plate, and the fin is kept an appropriate distance with the receiving pole-plate;
- wherein,
- the said fin is larger than the emitting pole-plate, and there is an inclining edge on the upper side of the fin;
- a further included insulation plate, which is located between the receiving plate and the circuit plate, and on which an opening groove is arranged at a position corresponding to the emitting pole-plate for providing it to protrude out the insulation plate, and the circumferential edge of the opening groove is arranged with protruding edge to make itself be just set in between the opening of the receiving pole-plate and the emitting pole-plate to prevent the emitting pole-plate and the receiving pole-plate from contacting to each other;
- a displaying unit further arranged on the controlling unit at least displays the sensed temperature value and water containment value.
