Product Description:
Strain gauge is made under the strain effect of the sensing element.
Strain through the adhesive paste
on the elastomer. In the measurement of strain, the adhesive formed layer plays a very important role. it has to be correctly passed to the elastic strain sensitive to gate up.
The large Adhesive extent affects the operating characteristics of strain gauges, such as creep, hysteresis, zero drift, sensitivity, linearity and influence of these features with the time, temperature level changing.
Strain gauges in the measurement process is a critical component, but the success or failure often depends on the choices of adhesives, pasing method is correct/wrong. Therefore, the selection of adhesives and paste process is a very important issue.
Load cell/Weighing sensor is a capable force of conveying gravity signals into electrical signals - An electrical conversion device, which is a key component of electronic weighing scales.
Load cell is actually an output device of a measurable electrical signal from power/force signal.The Actual working environment should be firstly considered when choosing load cells, which is essential for the correct selection of load cell. It relates to whether the sensor can work as well as its safety and service life, as well as the reliability and security of the whole weighing scales.
Choosing Load cells will accord to the factors as follows:
1.Working environment;
2.Selection of the number of sensors is based on the use of electronic weighing, scale body needing support points (support points should be based on the geometric center of gravity to balance body and the actual center of gravity coincides with the principle for determination).
The choice for capacity of the load cells can accord to the Max. weighing capacity;the number of load cells;the weight of the scale device;and the Maximum eccentric load and dynamic load to decide your options.
3.Sensor type selection depends largely on the type of weighing; installation space(Your housing shell of the scale), ensuring the installation for appropriate, safe and reliable weighing;
4. Al-type cantilever sensors are suitable for pricing scales, platform scales, hook scales, etc.; steel cantilever-type sensors for hopper scales, electronic belt weighers, sorting scales, etc.; steel bridge sensors are suitable for track scale, truck scale, crane scales, etc.; column sensor for truck scale, dynamic railroad scale, hopper scales and other large-tonnage.
5.Sensor choices according to the accuracy levels.
The accuracy level of sensors includes transducers, non-linear, creep, creep recovery, hysteresis, repeatability, sensitivity and other technical indicators.
When the choice of the sensor, not simply the pursuit of high-grade sensors, but it is necessary to take into account the accuracy of electronic scales to meet the requirements, and also consider its costs.
