How to choose a temperature and humidity sensor in the textile industry?
With the improvement of people's quality of life nowadays, the demand for the textile industry is also increasing, and the textile knowledge system and subject system continue to develop and improve accordingly. Whether the temperature and humidity in the textile industry is reasonable has a great impact on the normal production of enterprises. Under unreasonable temperature and humidity, not only can't produce high-quality products, but it will even have a serious impact on the normal operation of the equipment.
Below we will discuss the important environmental conditions in the textile production process-temperature and humidity.
The temperature and humidity in the air have a great influence on the production of textile technology. This is because textile materials (natural fibers and chemical fibers) are mostly hygroscopic or static-prone materials, such as common cotton fibers:
**Humidity: **Cotton After the relative humidity increases, the strength of the fiber can increase and improve the regularity of the long-chain molecules. Under the standard temperature and humidity conditions, the strength of the cotton fiber can be increased by 50% compared with that in the dry state. However, when the relative humidity exceeds 80%, the strength increase rate of cotton fiber decreases, and even has a tendency to decrease.
**Temperature:** Generally speaking, when the temperature is high, the energy of the fiber molecules of the cotton fiber increases, which weakens the gravitational force between the fiber molecules in some areas, so the tensile strength decreases. Some experiments show that the temperature rises by 1 ℃. The strength is reduced by about 0.3%.
In summary, the control of temperature and humidity in the textile workshop is the basis for ensuring the stable improvement of product quality and smooth production. So how do we choose a temperature and humidity sensor?
What is the function of the temperature and humidity sensor?
Temperature and humidity sensors mostly use temperature and humidity integrated probes as temperature measurement elements, which collect temperature and humidity signals and convert them into electrical signals or other required forms of signal output according to certain rules to meet user needs.
By installing temperature and humidity sensors, the temperature and humidity in the workshop can be effectively guaranteed, and the quality of textile materials can then be stabilized. Ensure that the temperature and humidity in the workshop and the moisture regain rate of semi-products are suitable for the production process; when the temperature and humidity in the workshop changes, the temperature and humidity are unstable, and the moisture regain rate does not meet the specified conditions, promptly remind the manager of the environment through SMS, webpage and other alarm functions Control and manage.
What kind of temperature and humidity sensor should I choose?
Wide measuring range:The temperature and humidity sensor of Jianda Nippon is an industrial-grade temperature and humidity sensor. The measurement range of the equipment can meet higher measurement requirements. Take the wall-mounted king-shaped housing temperature and humidity sensor as an example. The sensor's built-in probe working temperature and humidity is: -40℃ +60℃, 0%RH 80%RH, working temperature of extension probe: -40℃~+120℃ , default: -40℃~+80℃, working humidity of probe: 0%RH-100%RH.
**High measurement accuracy: **Textile materials are extremely sensitive to temperature and humidity. The temperature accuracy of ordinary temperature and humidity sensors is generally ±1~3℃, humidity ±5RH%; wall-mounted king-shaped housing temperature and humidity sensor, humidity ±3%RH( 5%RH~95%RH, 25℃), temperature ±0.5℃ (25℃). In contrast, industrial-grade temperature and humidity sensors can better meet the needs of textile workshops.
**High protection level: **The protection level of the wall-mounted king-shaped temperature and humidity sensor shell is IP65, dust-proof and anti-condensation performance, and it can work normally in harsh environments without being affected.
**High integration: **Ordinary temperature and humidity can only be used to measure temperature and humidity. The wall-mounted king-shaped temperature and humidity sensor can not only monitor temperature and humidity changes in real time, but the collected data can be directly transmitted to the computer in two ways, RS485 and analog. The terminal performs display, data storage and analysis, and can also be integrated with environmental monitoring systems and cloud platforms to realize remote control functions such as telephone alarms/ SMS alarms, and promptly remind managers to adjust the environmental temperature and humidity to ensure product quality.
The management of textile workshops must be scientific, institutionalized, and standardized. Controlling the moisture regain of semi-products and finished products in the production process, and at the same time starting from the process, equipment, environment, etc., to reduce the fluctuation of the moisture regain of each process is the basis for stabilizing product quality and ensuring stable production operation.
