Load Cell Constitute
The load cell is actually a device that converts the quality signal into a measurable electrical signal output. The sensor should first consider the actual working environment of the sensor, which is essential for the proper selection of the load cell, it relates to the sensor can work properly and its safety and service life, and even the entire instrument reliability and safety Sex. In the load cell main technical indicators of the basic concepts and evaluation methods, the old and new GB quality differences. There are several types of S-type, cantilever type, spoke type, plate ring type, membrane box type, bridge type, cylinder type and so on.
Variation refers to the weighing instrument measured variables (which can be understood as the input signal) from the differential bias to reach the same value, the instrument indicates the maximum difference between the value, probably said that the instrument in a strong external conditions, the measured Parameters from small to large change (positive characteristics) and the measured parameters from large to small change (reverse characteristics) is not uniform degree, the difference between the two is the instrument deterioration. Reliability Weighing control instrument reliability is the chemical industry instrument workers to seek another tension performance indicators. Reliability and instrument maintenance is the opposite phase, the instrument reliability is high to clarify the instrument maintenance is small, otherwise the instrument reliability is poor, the instrument maintenance is large. To deal with chemical enterprise testing and process control instruments, most of the placement in the process of pipeline, all kinds of towers, kettle, cans.
Weighing the sensitivity of the instrument occasionally also known as "magnification ratio", but also the static characteristics of the instrument on the slope of the points on the line. Increasing the magnification can increase the sensitivity of the instrument, simply increase the sensitivity does not change the instrument's basic performance, that is, weighing the accuracy of the instrument did not improve, on the contrary there will be signs of oscillation, resulting in unstable output. Instrument sensitivity should be tied to the appropriate amount.
