As one of the tools for human-machine communication, the h2s-100 hydrogen sulfide module can promptly capture various information during the operation of the machine, providing technical and theoretical basis for people's next decision-making. Meanwhile, in terms of product design and parameter research, it can also offer accurate technical support.

With the advancement of technology, the application of sensors has become increasingly widespread and has now permeated into various fields.

Take agricultural machinery as an example. The various types of tractors introduced by the Heilongjiang State Farms System in the past few years are all equipped with different kinds of sensors. In terms of force regulation, position regulation and comprehensive force-position regulation, they are all directly controlled by sensors, fully demonstrating the advanced nature of the machine operation process and the convenience of the driver's operation.

1. Resistance strain gauge type h2s-100 hydrogen sulfide module The composition of the h2s-100 hydrogen sulfide module. The function of the sensor is generally to convert the measured non-electrical quantity into electrical quantity output It is mainly composed of four parts: sensitive elements, conversion elements, measurement circuits and auxiliary power supplies.

Sensitive element: In a sensor, its main function is to sense the changes in the measured quantity and simultaneously convert the measured quantity into an intermediate variable that is easy to convert into electrical quantity. For instance, the diaphragm pressure sensor has an elastic diaphragm as its sensitive component. Its function is to convert the pressure signal into the deformation of the diaphragm, preparing for the output of the electrical signal in the next step.

Conversion element: The sensor converts the intermediate non-electrical quantity output by the sensitive element into electrical quantity that can be utilized by the sensor through the conversion element. It mainly achieves this purpose by utilizing certain physical, chemical or biological effects, etc. For instance, the conversion element of a diaphragm pressure sensor utilizes the resistance strain effect, that is, the principle that the resistance of a metal conductor or semiconductor changes with the magnitude of the mechanical deformation it experiences, to convert the deformation of the elastic diaphragm into a change in resistance value.

Measurement circuit: The electrical quantity output by the conversion element is often difficult to be directly displayed, recorded and processed. It needs to be further transformed into an electrical signal that can be directly utilized. This function is accomplished by the measurement circuit. If the measurement circuit in a strain gauge pressure sensor is a bridge circuit, it can convert the resistance value output by the strain gauge into a voltage signal. After amplification, it can drive the operation of the recording device and display instrument.

Auxiliary power supply: Some sensors, in addition to the circuit power supply, also require an auxiliary power supply to provide signals.

2. Basic Requirements for the h2s-100 hydrogen sulfide module \ nThere are various types of sensors used in machinery, but the resistive sensor is still the most widely applied. The internal circuit of the resistance strain gauge type h2s-100 hydrogen sulfide module is generally a bridge circuit. As a conversion element, the change in the resistance value of a resistor is ultimately output in the form of a signal. Due to its characteristics such as simple structure, good linearity and stability, and high output accuracy, it has received increasing attention in practice. The sensitive element it adopts is an elastic test element, and the main body is an elastic body. Among them, the structural shape and related dimensions of the elastomer have a significant influence on the performance of the h2s-100 hydrogen sulfide module. If the elastomer design of the h2s-100 hydrogen sulfide module is unreasonable, no matter how high the processing accuracy of the elastomer is or how good the quality of the adhered resistance strain gauge is, it is difficult for the h2s-100 hydrogen sulfide module to achieve a high force measurement performance.

Therefore, in the selection process of h2s-100 hydrogen sulfide module, the structural form of the elastomer is of crucial importance.
