Hua'an is a pacifier thermometer chinese manufacturer
,pacifier thermometer mainly composed of a pacifier, stopper, heat sensing cable and LCD monitor from
Electronic thermometer temperature sensor, LCD display, button cell, application specific integrated circuits and other electronic components and parts. Can quickly and accurately measure the body temperature, compared with the traditional glass mercury thermometer, with easy reading, measurement time is short, high accuracy, and has the advantage can remember Beeper, especially electronic thermometer mercury-free, and on the human body ambient sound, especially suited to the occasion families, hospitals and other uses.
Electronic thermometers use of certain physical parameters of the material, such as resistance, voltage, current, etc., to determine the relationship between the ambient temperature and the temperature is displayed in digital form.
Its disadvantage is that by showing the value of factors affecting the accuracy of electronic components and battery-powered status, as glass thermometer.
Use of semiconductor resistance with temperature change characteristics
Electronic thermometer is the use of a temperature sensor output signals, digital signals or direct output then current signal (analog signal) into an integrated circuit that can be identified by the internal digital signal, and then through the display (such as LCD, LED tube, LED matrix, etc.) the temperature is displayed in digital form that can record, read the maximum value of the measured temperature.
The core element is the perception of temperature electronic thermometer NTC temperature sensor. Sensor resolution up to ± 0.01 ?, accuracy up to ± 0.02 ?, the reaction rate <2.8 seconds, the resistance in the drift rate ≤ 0.1% (equivalent to less than 0.025 ?).
