How do temperature and humidity sensors work in industrial production?

Why is temperature and humidity important to industry?

• In the industrial production process, temperature and humidity is one of the important environmental parameters affecting product quality. 

Different materials and products have different requirements for temperature and humidity conditions. If the temperature and humidity are out of control, it may directly lead to product quality problems and losses. Therefore, in the production and process development stage, accurate temperature and humidity measurement and strict environmental control are needed to determine the optimal process conditions and quality characteristics of the product.

On the basis of fixed process conditions, continuous monitoring and recording of temperature and humidity parameters can also help to identify problems, track down causes and optimize process solutions. Strict temperature and humidity measurement is an important means to realize high quality and efficient production.

• Different kinds of products and processes have different requirements for temperature and humidity conditions. 

For example, in the chemical industry, the temperature and humidity in the reactor directly affect the reaction rate and yield. In food processing, temperature and humidity control is critical to product quality and shelf life. Accurate real-time monitoring of temperature and humidity parameters can help detect abnormalities in the process, such as high reactor temperatures due to the heat generated by the reaction, or high ambient humidity affecting the quality of the product packaging.

Once the problem is detected, the process parameters or environmental conditions can be quickly adjusted to avoid a large number of defective products. Therefore, real-time temperature and humidity monitoring is very important for industrial process quality control.

How to choose temperature and humidity sensors for industrial equipment?

1. Measurement range. Select the appropriate measurement range according to the temperature and humidity variation range of the process.

2. Response speed. For fast-changing processes, a sensor with a fast response time is required.

3. Stability and Accuracy. Choose a stable and reliable sensor with accuracy that meets the needs of process control.

4. Operating Environment. Consider the temperature, pressure, corrosive gases and other conditions to choose the appropriate sensor.

5. Interfaces are adopted. Standardized digital or analog output, easy to connect to the control system.

6. Protection class. According to the actual environment to choose the appropriate level of protection.

7. Price. According to the accuracy requirements to choose the appropriate cost-effective products.

8. Service life. Industrial applications require products that are stable for long periods of time.
