S weighing sensor
S load cell is actually S-type pressure sensor. S-type pressure sensor is a large category of load cell. It has the function of tension and compression. Both tension and pressure can measure its anti-eccentric load ability. In many sensors Among them, the measurement effect is among the best, which is mainly due to its advantages of high accuracy and good measurement range. Next, the weighing sensor supplier Ningbo SAINTBOND will introduce the related common sense of the equipment in detail to help everyone have a more comprehensive understanding of the product.

The S-type pressure sensor is based on the principle: the elastic body (elastic element, sensitive beam) produces elastic deformation under the action of external force, so that the resistance strain gage (conversion element) pasted on its surface is also deformed. After the resistance strain gage is deformed , Its resistance value will change (increase or decrease), and then the resistance change will be converted into an electric signal (voltage or current) by the corresponding measuring circuit, thus completing the process of transforming the external force into an electric signal.

S-type load cell has the function of tension and compression: both tension and pressure can measure its anti-eccentric load ability, and it is also among the best in many sensors. Its advantages are high accuracy, good measurement range, easy installation and many applications in the packaging industry. The S-type load cell-101BH provided by has the advantages of tension and compression, IP67 protection level, strong versatility, high sensitivity, high reliability, long life, and anti-electromagnetic interference. It can be used for tension weighing and pressure weighing. The weight is 50kg-2t, which can be used in hook scale, silo/funnel/tank weighing, crane scale, forklift scale, metering/filling, tensile/tension measurement, testing machine, mixing station, etc.

S-type load cell installation method:
1: Select the appropriate sensor range and determine the rated load of the sensor used according to the required working environment. Although the load cell itself has a certain overload capacity, this situation should be avoided as much as possible during installation and use. Sometimes a short-term overload may cause permanent damage to the sensor.
2: The load cell should be handled with care, especially for the small-capacity sensor that uses aluminum alloy material as the elastic body. Any shock or drop caused by vibration is likely to cause a large output error.
3: Wiring according to the instructions before installation, common wiring method: red is the positive pole of the power supply, connected to EXC+, the black wire is the negative pole of the power supply, connected to EXC-, the green wire is the positive signal of the signal, connected to SIG+, and the white wire is the signal The negative pole, connected to SIG-, the blue wire is the positive feedback, connected to SEN+, the yellow wire is the negative feedback, connected to SEN-, the color of the wire may be different when each manufacturer leaves the factory, please connect according to the manual.
4: The sensor housing, protective cover, and lead connector are all sealed and cannot be opened at will. The cable should not be lengthened by itself, because the sensor cable has been adjusted according to the output resistance value at the factory, and if it is lengthened or shortened by itself, it will affect the output of the sensor. Resistance, in order to affect the accuracy of the entire sensor, if it really needs to be lengthened, it should be soldered at the joint, and moisture-proof sealant should be added, and the resistance should be added again to adjust to the factory default output resistance.
5: The cable of the sensor should be far away from the strong power supply line or the place with pulse wave, which can reduce the signal output of the sensor from the field interference source, reduce the error and improve the accuracy.
6: In high-precision applications, the tension sensor and instrument should be used after preheating for 30 minutes.
7: When purchasing a sensor as a spare part, the load cell should be stored in a dry, ventilated and non-corrosive gas room.

S-type pressure sensor application range:
On the basis of independent innovation, Ningbo SAINTBOND has developed and produced hundreds of varieties of various sensors of Limin series, various application instruments and systems, and various crane overload protection devices, which can be widely used in oil fields, chemicals, automobiles, and cranes. Heavy machinery, construction, building materials, mechanical processing, thermal power, military industry, transportation and other fields.
