What is a single temperature ultra-wide temperature sensor?
Temperature is a physical variable related to the cold and heat of objects. In industrial production and life, we often encounter problems about temperature measurement and control, especially in refrigerated warehouses, tobacco, steel and other industries, for ultra-high and low temperatures. The environment has very high requirements, which puts forward higher requirements on temperature sensors, so ultra-wide temperature sensors that can be used in different occasions have become the focus of research. Temperature dynamic characteristics Dynamic characteristics specifically refer to a functional relationship between the output temperature increase in the temperature sensor and the measured temperature increase. If the input temperature and the output temperature are If the change is the same, that is the embodiment of an ideal temperature sensor. But this is impossible in the actual measurement process, so it is necessary to minimize this gap so that the rapid change of the measured temperature with a short period of time can be measured in the most realistic way. Temperature dynamic characteristics and ultra-wide temperature sensor Various industries attach great importance to the method of temperature sensor dynamic characteristics, because if the temperature sensor does not adequately respond to the dynamics, it will be impossible to get the measured The real data and changes of temperature seriously reflect the quality of industrial production. Therefore, it is necessary to study the improvement method of this dynamic characteristic. The relationship between the ultra-wide temperature sensor and the dynamic characteristics is that the ultra-wide temperature sensor has particularly high requirements for temperature monitoring. It not only needs to meet an extremely wide temperature measurement range, but also needs to be more sensitive to temperature changes. The change between the output temperature meets the standard of use. Ultra-wide temperature sensorUltra-wide temperature sensor is mainly used for real-time temperature change monitoring in ultra-high temperature or ultra-low temperature environment. The difference between it and the ordinary temperature and humidity sensor is the working temperature range. The working range of the ordinary temperature and humidity sensor is -40~80℃, while the measurement range of the ultra-high and low temperature sensor is －100~300℃, so its remarkable feature is resistance High temperature and low temperature resistance. Using large-screen LCD display, with automatic temperature recording, temperature upper and lower limit dual control, limit free setting, temperature calibration by password, RS485 data transmission and other functions. Using high-sensitivity temperature sensing elements, the sensor has the characteristics of high measurement accuracy and strong anti-interference ability. The ultra-wide temperature sensor adopts large-screen LCD display, with automatic temperature recording, temperature upper and lower limit dual control, limit free setting, temperature calibration by password, RS485 data transmission and other functions. The product adopts high-sensitivity temperature sensing element, and the sensor has the characteristics of high measurement accuracy and strong anti-interference ability, which ensures the excellent measurement performance of the product. This product uses a high-definition LCD screen to display the temperature value in real time; the internal real-time record of the monitoring equipment is convenient to retrieve the monitoring data at any time, and it can also be synchronized with the monitoring platform software; the internal integrated alarm function module (buzzer Or relay), can alarm when the temperature exceeds the upper and lower limits; RS485 signal output, standard MODBUS-RTU communication protocol, the maximum communication distance can reach 2000 meters (measured); the maximum number of networks can be up to 254, which is an excellent intelligent type Industrial-grade ultra-wide temperature transmitter. Ultra-wide temperature sensor application scenariosUltra-wide temperature transmitter (low temperature) is widely used in ultra-low temperature refrigerators, freezer warehouses and other environments. The temperature measurement range is -100~+200℃. Ultra-low temperature probe, this probe is waterproof and accurate in measurement. Ultra-wide temperature transmitter (high temperature) is widely used in ovens, tobacco, steel heat treatment and other industries. The temperature measurement range is 0~300℃, and the ultra-high temperature probe is used for accurate measurement.
