Abstract
The utility model discloses a digital solid small telescopic experiment detector, which comprises a base, a circuit box, a digital shift sensor, a temperature sensor, a data general purpose interface, a display screen and a solid clamp. A current apparatus detects and demonstrates solid's expansion caused by heat and contraction caused by cold via dial indicator measurement or throw of pointer, the measurement is not accurate, the display is not visual and obvious enough, especially that the expansion coefficient of solid material can not be measured directly, but read and calculated manually, thus having the drawbacks of reading deviation and complex operation. According to the utility model, a digital shift sensor is applied to solid small telescopic experiment detection, measured data can be displayed and transmitted in digital mode, connected to a computer for automatically reading and calculating, such that the measurement is more accurate, the display is more visual, and the operation is more convenient.
Description
Technical field:
The utility model relates to a kind of measurement mechanism, is the small flexible experiment detector of a kind of digital solid specifically.
Background technology:
Many solid materials all need to measure its expansion coefficient; Need to demonstrate by experiment the phenomenon of expanding with heat and contract with cold in middle and primary schools.The device that existing detection and demonstration solid expand with heat and contract with cold is to measure by needle deflection or dial gauge, accurate inadequately, and show directly perceived inadequately and obvious, particularly can not directly measure the expansion coefficient of solid material, need to have shortcomings such as deviation of reading and complex operation by artificial reading and calculating.
The utility model content:
The purpose of this utility model provides the small flexible experiment detector of a kind of digital solid.
The purpose of this utility model is to adopt following technical scheme to realize: digital displacement sensor is applied in the small flexible experiment detection of solid, and measurement data shows and transmission by numeral, connects with computer and carries out automatic reading and calculating.Be fixed with circuit box on the base, supply hub, data general-purpose interface and temperature sensor interface are housed on the circuit box, display screen and reset key are equipped with in the circuit box front, circuit box links to each other with digital displacement sensor by data line, detection head is housed on the digital displacement sensor, geometrical clamp is housed on the detection head, and digital displacement sensor one end is equipped with geometrical clamp.Make measurement more accurate, show more directly perceived, more convenient to operate.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Embodiment:
As shown in the figure, base 1, circuit box 5, supply hub 2, data general-purpose interface 3, temperature sensor interface 4, display screen 6, reset key 7, data line 8, digital displacement sensor 9, detection head 10, geometrical clamp 11 and 12.During use, detected material 13 is fixed between geometrical clamp 11 and the geometrical clamp 12, energized, press reset key 7, the temperature of change detected material or other influence its flexible factor, just can show accurately that on display screen 6 it is small flexible, data can be shown by data general-purpose interface 3 and temperature sensor interface 4 input computers and handle, and measure the expansion coefficient of detected material.
