(1) messenger wire plus tape measure method: This is a relatively primitive method and the earliest taper measurement method used by people. Its characteristics are troublesome measurement, low data accuracy and high reliability; Of course, there are also units that directly make a molding size and measure the difference between the upper and lower mouths with a tape measure. The principle is similar.
(2) Measurement method of mechanical taper instrument: The principle is a specially designed mechanical lever and intelligent display instrument, and the zero position is adjusted on a special calibration platform. The value displayed on the display instrument is the difference between the upper and lower ports. Its characteristic is that it can completely overcome the influence of on-site vibration signals and interference signals, and it can also overcome the influence of temperature, so the number of responses is true and accurate. The patented mechanical taper meter developed by Wuhan Jiate has the characteristics of convenient measurement, accuracy, good repeatability and strong anti-interference ability, and is an ideal taper detection equipment.
(3) Electronic Taper: Its principle is to use the inclination sensor as the original measuring device, to process the measured data with analog circuit or digital circuit, and to display the measured data with LCD. It is characterized by convenient measurement setting, intuitive display and convenient zero calibration. However, due to the great influence of temperature on electronic components, the zero point is easy to drift, and the field interference signal and vibration signal have an influence on the measurement results, and now there is a trend of gradual elimination;
(4) Computer-based taper meter: Its principle is to use special high-precision inclination sensor and data processing circuit as the original measuring device to filter out the influence of temperature and vibration, which can work in the range of -20℃~80℃, and use industrial tablet computer as the data processing center and display device. It is characterized by convenient measurement setting, intuitive display and convenient zero calibration, and the temperature has no influence on the measurement results. The new computer taper meter developed by Wuhan Jiate is an ideal choice for measuring the taper of slab.
