Hua'an main produce predictive digital thermometer
,predictive digital thermometer is one type of thermometer. Depending on the material used in different temperature ranges and temperature.
Digital thermometer with high precision assembly of imported chips, high stability, error ≤ 0.5%, the power supply, micro-power, stainless steel housing, protective rugged, beautiful and delicate.
Digital thermometer using imported high-precision, low drift, ultra-low power integrated circuits and wide temperature LCD display, built-in high-energy batteries ≥ 5 years of continuous work without laying power cables, is a high accuracy, good stability, applicability pole Strong new site temperature indicator. Is the ideal spot pointer bimetal thermometers traditional alternative products, widely used in various industrial and mining enterprises, universities, research institutes.
Temperature number of our daily life and production in real time exposure to the physical, but it is invisible, feeling alone can only feel about the temperature, although the traditional pointer thermometer can indicate temperature, but low accuracy, easy enough to use, display and intuitive enough, the emergence of the digital thermometer allows people to intuitively understand they want to know is how many degrees the temperature in the end.
Digital thermometer using a temperature sensitive element is a temperature sensor (such as a platinum resistance, thermocouple, a semiconductor, a thermistor, etc.), the transition temperature is changed to signal changes, such as changes in voltage and current, temperature and electrical signals changes in a certain relationship, such as a linear relationship, the relationship between a certain curve, the electric signal may be used i.e., analog to digital conversion circuit AD conversion circuit converts the analog signal to a digital signal, the digital signal is then sent to a processing unit, such as a PC or a microcontroller etc., the processing unit through the internal software of this digital signal and the calculated temperature of the link, it becomes possible to display the temperature value, such as 25.0 ° C, and then through the display unit, such as LED, LCD or other display screen, the computer gives out observation. This completes the basic digital thermometer temperature measurement function.
