Description
Technical field
The invention belongs to and measure and the control technology field, particularly a kind of measuring method of strength of fluid also relates to a kind of measurement mechanism of this strength of fluid simultaneously.
Background technology
At present, existing various sensing devices can not be used for measurement gas and strength of fluid, adopt chemico-analytic method and the measuring method of existing gas and strength of fluid, and chemical analysis method efficient is low and directly perceived inadequately, is not easy to realize automatic control.

In order to achieve the above object, technical program of the present invention lies in having adopted a kind of strength of fluid measuring method, this method comprises the steps:
(1) in unknown concentration liquid, puts and establish a reflective mirror;
(2) use the launching fiber that acutangulates angle with reflective mirror to insert in the liquid, make the end face of launching fiber parallel with minute surface;
(3) on launching fiber beam reflection direction, be provided with one and receive optical fiber;
(4) inject the light beam of setting intensity by launching fiber;
(5) collect folded light beam by receiving optical fiber;
(6) photoelectric tube is set receiving the optical fiber exit, the power of the light signal that transforms by photoelectric tube is calculated the magnitude numerical value of strength of fluid.
Simultaneously, technical program of the present invention also lies in carrying a kind of measurement mechanism that utilizes this method to measure, this device is made of the reflective mirror of installing in support, the support, launching fiber and reception optical fiber, launching fiber is fixed on the support and with reflective mirror and becomes to set acute angle, make the end face of launching fiber parallel with minute surface, be fixed with reception optical fiber on the support of launching fiber emission beam reflection direction, the exit that receives optical fiber is provided with photoelectric tube, and the output of photoelectric tube connects computing equipment.
The present invention is characteristic and the different medium density rule different to the refractive index of light of using anaclasis, realizes the detection of convection cell concentration by photoelectric effect.Because refractive index and density of medium have funtcional relationship, when the concentration of measured medium increased, the refractive index of medium increased.Because of the increase of refractive index, the reflection spot of Light in Medium bundle and reflective mirror skew, the angle of two-beam increases simultaneously, receives the area that optical fiber is irradiated to and increases, and institute's light intensity that receives increases, the electric signal enhancing that photoelectric tube is exported.
