, Detailed introduction of stainless steel platform scale
, Stainless steel platform scale is made of stainless steel and carbon steel. If it is used in the food industry, the scale design must have no sanitary dead corners. If it is a highly corrosive environment, the material must be polished with stainless steel.
, Yuheng's sensor sensor is the core technology of the platform scale. Most of the domestic sensor production technology is made by hand. Most of the foreign sensors are automated and flexible manufacturing, so their performance is much better. However, the price is relatively high.
, The instrumentation of stainless steel platform scales is mainly considered from two aspects. One is the mechanical performance of the instrument, which is the protection level of the instrument itself. The second is the electrical performance of the instrument, the instrument's resolution, zero return speed, display stabilization time, etc. The most important thing is to see whether the function of the instrument is powerful. For example, printing to connect to a computer
, unlimited connection to an enterprise
, system, etc.
, At present, the price of domestic platform scales is relatively low, but there is still a big gap between the accuracy, stability and service life of scales and the Sigang Sartorius brand. At the same time, the price and accuracy of the scale are directly proportional. The higher the accuracy requirements, the corresponding price will be higher.
, Stainless steel platform scale consists of
, type stainless steel platform scale is a fully electronic weighing device, which consists of
, series of high-precision sensors and
, display with single-chip microcomputer. Therefore, its weighing is fast and accurate, its performance is stable and reliable, and it has complete functions. The display and weighing platform can be separated or connected into an integrated device according to the user's needs. This product has beautiful appearance and sturdy and durable structure, making it suitable for commercial automatic weighing.
, The main function of the stainless steel platform scale is automatic zero tracking, zeroing, tare weight, unit price and amount calculation
, various unit price setting amounts, cumulative total, overload and overvalue alarm error message
, prompting power supply AC and DC two When the machine is empty, it automatically enters the low-power energy-saving state. The digital voltmeter self-tests and automatically shuts down when the voltage is insufficient.
, Methods to reduce errors in the design and production of stainless steel bench scales
, Guarantee of sensor technical indicators
, Selecting sensors whose technical indicators meet accuracy requirements is the key to ensuring the quality of stainless steel bench scales. Linearity, creep, no-load temperature coefficient and sensitivity temperature coefficient are important indicators of the sensor. For each batch of sensors, sampling inspection and high and low temperature experiments must be carried out in accordance with the sampling rate required by relevant national standards.
, Temperature coefficient of stainless steel platform scale circuit
, Theoretical analysis and experiments prove that the temperature coefficient of the input resistance of the input amplifier and the feedback resistance are important factors affecting the temperature coefficient of the sensitivity of the stainless steel platform scale. The temperature coefficient must be selected

, metal film resistors. Every stainless steel bench scale produced must undergo high temperature testing. For some products with a small amount of temperature coefficient out of tolerance, metal film resistors with temperature coefficients smaller than

,
, can be used for compensation. During the high-temperature test, the product was subjected to temperature aging to improve the stability of the product.
, Nonlinear compensation of stainless steel platform scale
, Under ideal circumstances, the digital quantity after analog-to-digital conversion of the stainless steel platform scale and the weight applied to the stainless steel platform scale should have a linear relationship. When calibrating accuracy during production, an in-house computer program is used for single-point correction. The slope of the number and weight is calculated according to the ideal straight line and stored in the memory. This makes it impossible to overcome the nonlinear errors produced by the sensor and integrator. Using multi-point correction and using multiple straight lines to approximate a curve effectively reduces nonlinear errors without increasing hardware costs. For example,
