Today, the application of civil Temperature and humidity sensor is more and more common, but industrial temperature and humidity sensors still occupy a dominant position.
Temperature and humidity sensors are widely used in modern society. Computer room, industry, agriculture, warehouse, etc. are inseparable from temperature and humidity management, especially in the real-time recording of temperature and humidity changes. The T/H sensor can use the recorded data. Scientifically and effectively analyze and manage different fields. Today, the application of civil Temperature and humidity sensor is more and more common, but industrial temperature and humidity sensors still occupy a dominant position.
Question: Both are used for temperature and humidity measurement. What is the difference between an industrial-grade temperature and humidity sensor and an ordinary temperature and humidity meter?
1.Wide measurement range: General temperature and humidity meter, temperature measurement range is -10 ~ 50 ℃, humidity is 20% RH ~ 99% RH when the temperature and humidity value is too large, the device is easy to damage. The measurement range of the industrial temperature and humidity sensor can meet the higher measurement requirements. Taking the wall-mounted king-case temperature and humidity sensor as an example, the sensor circuit operating temperature and humidity: -40℃~+60℃, 0%RH ~80%RH, probe working temperature: -40℃~+120℃ Default: -40℃~+80℃, probe working humidity: 0%RH-100%RH.
2.High measurement accuracy: common temperature and humidity sensor, temperature accuracy are generally ±1~3℃, humidity ±5RH%; Industrial-grade wall-mounted king-shaped shell temperature and humidity sensor, humidity ±3%RH (5%RH~ 95%RH, 25°C), temperature ±0.5°C (25°C), ordinary temperature and humidity sensors cannot achieve this accuracy.
3.High integration: ordinary temperature and humidity can only be used to measure temperature and humidity, industrial-grade wall-mounted king-shaped shell temperature and humidity sensor can not only monitor the temperature and humidity changes in real-time, the collected data can be directly RS485, analog two The method is transmitted to the computer for display, data storage, and analysis, and can also be integrated with the environmental monitoring system and cloud platform to achieve remote control functions such as phone alarms/short message alarms.
4.Fast frequency response: The frequency response characteristic of the temperature and humidity sensor determines the frequency range to be measured. The measurement conditions must be maintained within the allowable frequency range without distortion. The sensor response always has a certain delay. The shorter the delay time, the better. The frequency response of the sensor is high, and the measurable signal frequency range is wide. Industrial-grade wall-mounted king-case temperature and humidity sensor, humidity response time: ≤4s (1m/s wind speed) temperature response time: ≤15s (1m/s wind speed), which is incomparable with daily temperature and humidity meters.
5.Industrial protective shell: As an industrial-grade sensor, it needs to adapt to a variety of harsh environments. The shell is sealed and sealed, waterproof, and temperature-resistant. In high dust and rain environments, Besides, the equipment can also work normally without being affected, providing conditions for accurate measurement of industrial temperature and humidity.
6.Special probe: industrial grade temperature and humidity sensor can use different probes in different situations.
