In today's small scales, all use high-precision resistance strain gauge load cells. Small size, high precision and easy maintenance. Equipped with digital display instruments, the production and life are greatly facilitated. Now weighing instruments up to the kiloton level, balances as small as a few tens of grams can be replaced with load cells, and the original mechanical sensors are discarded.
A small floor scale generally has four sensors to eight sensors. It is installed smoothly under the small scale platform. The installation of the small floor scale is very demanding and needs to be installed by a professional professional installation technician. In the installation, there are generally four corner errors of the sensor, the balance of the weighing platform, and the like. The temperature compensation of the sensor is also adjusted according to the needs of the use of the environment. The final step is to calibrate the sensor's weighing range. Once the calibration is complete, it will work.
The load cell is actually a device that converts the mass signal into a measurable electrical signal output. It refers to a force sensor used on the electronic scale, which can convert the gravity acting on the measured object into a certain proportion. The measured output signal is measured by converting one of the measured (mass) to another measured (output) after taking into account the effects of gravity acceleration (g) and air buoyancy (f) at the place of use. The force of the sensor. . The sensor should first consider the actual working environment of the sensor. This is very important for the correct selection of the load cell. It is related to the normal operation of the sensor, its safety and service life, and the reliability and safety of the entire scale. Sex. In the basic concepts and evaluation methods of the main technical indicators of the load cell, there are qualitative differences between the old and new national standards. There are several types of S-type, cantilever type, spoke type, plate ring type, bellows type, bridge type, and column type.
My company specializes in selling all kinds of load cells, friends in need can come to consult! Our company has more products: weighing sensors, electronic scales, junction boxes, weight transmitters, etc., please feel free to inquire!
