The company is a professional manufacturer of digital temperature sensors. The digital temperature sensors produced are widely used in all walks of life. The performance indicators of related products are in line with the relevant national standards, and you can rest assured to purchase.
Digital temperature sensor is a kind of sensor that can convert temperature physical quantity and humidity physical quantity into digital quantity directly through data acquisition equipment such as computer, plc, and intelligent instrument through temperature and humidity sensitive components and corresponding circuits, and can realize temperature and humidity etc. 24 hours real-time monitoring of parameters, and real-time display of temperature and humidity measurements at each location on the monitoring host in the central control room.
In the process of selecting digital temperature sensors, we should not only pay attention to price factors, but should comprehensively consider various factors, including:
1. Whether the temperature of the measured object needs to be recorded, alarmed, and automatically controlled, whether it needs long-distance measurement and transmission;
2. When the temperature of the measured object changes with time, the lag of the temperature measuring element can adapt to the temperature measurement requirements;
3, the size of the temperature range and accuracy requirements and the appropriate temperature measurement element size;
4. Whether the environmental condition of the measured object has any damage to the temperature measuring element.
The following Xiaobian specifically for everyone to introduce what the different types of digital temperature sensors have different characteristics.
1. The selection of the digital temperature sensor is mainly based on the measurement range. If the measurement range is expected to be within the total range, the platinum resistance sensor can be used.
2. A narrower range usually requires the sensor to have a relatively high basic resistance in order to obtain a sufficiently large resistance change. The sufficiently large resistance change provided by the thermistor makes these sensitive elements very suitable for a narrow measurement range.
3, if the measurement range is quite large, then the thermocouple is more suitable.
