Chat: how about weighing sensor works and how to choose

Weighing sensor manufacturers - Katie, how to introduce you to weighing sensor works and how to choose. Speaking of weighing sensor, a lot of people the impression is used to measure the object weight machines. In fact, this was not entirely correct. Weighing sensor is applied in many fields. The principle of the sensor and the pressure sensor is similar, but different shape. Where modern science and technology using the weight of the sensor. Weighing sensor is a kind of convert quality signals into electrical signals and output devices can be measured. Sensors the basic concept of the main technical indicators and evaluation methods with new and old national benchmark has a qualitative difference. There S type, cantilever type, sports, plate ring type, bellows type, bridge type and column type. The movement principle of weighing sensors are two basic structure: linear and rotary ( Disc) 。 Measuring sensor by sliding fixed-length ( Linear type) Or relative motion rotator and state ( Rotary type) Composition. right The two types of load sensitive synchronizer was made by the same process. First, use the electrical conductivity of copper foil ( 0. 04 - 0. 5 mm thick) In the magnetic material ( For example, mild steel or glass) The substrate insulation measuring element, according to the design request for lithography or chemical etching. Copper foil carved by different refractive plane coil line, called printed circuit line. Slides, rotator and stator coil wire distribution is different. Stator and rotator volume line is a continuous line, the volume of the slider and the state of the line were long axis. Volume line were divided into two groups, the 7 r left space of the phase Angle of phase difference, called the action principle of weight sensor sine volume line. Inductosyn continuous roll of line and line of the segment volume is equal to the transformer a roll line and the second line, using ac electromagnetic field and the principle of mutual induction. According to the transform method, is divided into eight kinds of weighing sensors. 1, resistance distortion resistance distortion is widely used, its action principle is when distortion slice deformation resistance to resistance to change. Mainly by the elastic element, distortion resistance meter, measuring circuit and transmission cable. 2, the hydraulic oil pressure type sensor has simple structure, strong, large measuring range, but the precision is generally not more than 1/100. 3, capacitance, the vibration frequency of the oscillation circuit using capacitor and plate spacing d f. Capacitance sensor of low power consumption, low cost, with the accuracy of 1/200 to 1/500. 4, overlapping digital sensor is the power of gravity can be converted into electrical signals Electrical switching device. Mainly resistance distortion measuring sensors, electronic amplifier, analog conversion technology and microprocessor with the combination of new sensors. Digital weight sensor and digital measurement technology development gradually become heavy technology in the field of new pet. Performance in the field with the advantages of simple and effective debugging and on-site to adapt. 5, the disc ring plate ring type structure of weighing sensor by clear stress line distribution, output, high sensitivity, whole elastomer, simple structure, steady stress state, the advantages of easy processing. Now, the sensor's output accounts for a high proportion of, however, the design of the sensor the structure type is not complete. 6, when the vibration type elastic element stress, the natural vibration frequency and force is proportional to the square root. By measuring the change of natural frequency, can get the power of the elastic elements play a role for the measured object, and to determine its quality. There are two kinds of vibration transducer string and a tuning fork. 7. Gyroscope sensor with high response time ( 5 seconds) , hysteresis property, good temperature characteristic ( 3 ppm) , small vibration effect and accurate measurement precision, high resolution measurement precision. 8. Photoelectron is grid type and encoding plate type. Optical sensor is mainly used for electrical and mechanical combination proportion.
