Embodiment
Understand for the ease of those of ordinary skill in the art and implement the utility model, below in conjunction with the drawings and the specific embodiments, the utility model being described in further detail.
As shown in Figure 1, the tensiometer sensor that the utility model provides, comprises the first hole 2 and the second hole 3 arranged in the middle of crossbeam 1, crossbeam 1, is arranged on the first resistance 4, second resistance 5 of crossbeam about 1 both sides, the 3rd resistance 6 and the 4th resistance 7.Be communicated with between first hole 2 and the second hole 3.Wherein, one end of crossbeam 1 is fixed.First resistance 4, second resistance 5, the 3rd resistance 6 and the 4th resistance 7 are strain resistor.First resistance 4, the 4th resistance 7 and the second resistance 5, the 3rd resistance 6 parallel connection, form Hui Sideng full-bridge circuit.
Four strain resistor R are had in diplopore beam upper and lower surface
1~ R
4, the Hui Sideng full-bridge circuit shown in composition diagram 2.When F acts on diplopore beam, R
1, R
2stretched, resistance value increases; R
3, R
4be compressed, its resistance reduces.Now electric bridge out of trim, produces U
ovoltage exports, namely
Uo＝Ui·ΔR/R＝kεUi
Wherein, k is sensitivity coefficient, and ε is strain, U
ifor input voltage.Then the strain of diplopore beam is:
ε＝3F(d-a/2-δ)/(Ebh
3)
Wherein d is the distance of beam-ends to beam center, and δ is the distance of beam-ends to strain resistor, and h is cantilever thickness, and b is beam width, and E is the elastic modulus of material, and a is that strain resistor base is long.Then the output voltage of diplopore beam sensor is:
Uo＝3kFUi(d-a/2-δ)/(Ebh
3)
Visible, output voltage U
obe directly proportional to external force F.
Due to 4 strain resistor composition full-bridge differential circuits of diplopore force sensor beam, therefore output voltage is highly sensitive, and the linearity is good, but its output voltage is 10
-4~ 10
-6v level, signal is very faint, must amplify through certain multiple, could identify by computer data acquisition system.In addition, when the change in location of stress point, the moment of flexure in a hole increases, and the moment of flexure in another hole reduces, this can in bridge auto-compensation, thus improve the precision measured.
The tensiometer strain transducer chip electric resistance sensor that the utility model provides take foil gauge as the sensor of sensing element, and have the following advantages relative to traditional sensors: precision is high, measurement range is wide; Long service life, stable and reliable for performance; Structure is simple, size is little, lightweight, test time, on workpiece duty and stress distribution impact little; Frequency response characteristic is good; Can in high/low temperature, at a high speed, high pressure, judder, high-intensity magnetic field, to work under the severe environmental conditions such as nuclear radiation and chemical corrosion; Low cost of manufacture, low price.
The embodiment of the above is better embodiment of the present utility model; not limit concrete practical range of the present utility model with this; scope of the present utility model comprises and is not limited to this embodiment, and the equivalence change that all shapes according to the utility model, structure are done is all in protection domain of the present utility model.
