While there are endless applications of infrared thermometers, check out the below three areas where these non-contact temperature measurement devices are most relevant. It consists of a thermistor to sense the temperature and an electronic display of the temperature.

They should produce accurate readings when used correctly. The microcontroller receives this digital input and displays it on the LCD interfaced to it. In the above system, the temperature IC first measures the ambient temperature and converts this temperature to digital data and feeds it to the microcontroller which displays the temperature reading on the display. Design Files and Demo Boards. So now let me know more about the practical applications of Digital Thermometer? A thermometer is a device used to measure the temperature of any particular device or living body and displays the reading. A digital thermometer is familiar to everyone, from its use at the doctor’s or at home. A digital solid state thermometer provides an excitation current to the sensor and measures the linear (mV/°) signal from the sensor. What are Ferromagnetic Materials – Types & Their Applications, Digital Medical Thermometer by rambergmedia by, NTC bead type thermistor by Ansgar Hellwig by. Probe and ear digital thermometers are the two most common types. Digital Thermometer ref ECT-1: It measures temperature from 32⁰C to 42⁰C with an accuracy of 0.1⁰C. Digital thermometers measure body temperature over a small temperature range centered around 37°C. These thermometers are mostly probe type or ear type. Using the push button switches the user-defined temperature can be set. Temple and … 2. Accessibility Connected Thermometer Demonstration; ECG. | Respected Sir, Can i get a power point presentation on the above topic that can be presented in a seminar? Mouser Electronics United Kingdom - Electronic Components Distributor. Also, these thermometers cannot be used at low temperatures. Hi Upasana, For more ideas on seminars please checkout the link. how to program the two ics in the automatic thermometer. It measures oral, rectal, and armpit body temperature. Terms and Conditions | Please tell me working of this? Also, the thermometers are based on the expansion of matter with the rise in temperature and the readings were made from the scale readings. It is used to measure the temperature of solid and liquid food. Digital Solid State Thermometer. Medical Applications: The digital thermometers are used to measure human body temperature around 37⁰C. Some digital thermometer is having a wire approx 0.5 meter. The calibration is not accurate and can change easily. As the thermistor gets heated, its resistance increases or decreases (depending on whether it is a negative temperature coefficient or positive temperature coefficient). This bimetallic strip is attached to dial with a calibrated temperature scale to indicate the readings. It works on the principle that liquids expand on getting heated. Sitemap. Reply me at the earliest. Also, mercury has a low freezing point and cannot be used at places with low ambient temperature. A thermometer is a device used to measure the temperature of any particular device or living body and... 2 Kinds of Conventional Thermometers used earlier. Distance: The primary use of infrared thermometers is in measuring the temperature of a subject from a distance. However, a disadvantage of these thermometers is that they can measure temperature only up to a certain extent. Having read the above-written stuff, you must have by now had an idea about thermometers and the need to shift to a different approach to thermometers.
