It is the downward force of gravity that makes this thermometer work. The basic idea is that as the temperature of the air outside the thermometer changes, so does the temperature of the water surrounding the bubbles. As the temperature of the water changes, it either expands or contracts, ...
How Does A Thermometer Work Many commercial thermometers contain alcohol because alcohol has a low freezing point. As the temperature of the alcohol increases, it expands and causes the level within the thermometer to rise. The level of the alcohol corresponds to the printed lines/numbers on a t...
Thermistors have a variety of applications. They are widely used as a way to measure temperature as a thermistor thermometer in many different liquid and ambient air environments. Some of the most common uses of thermistors include: Digital thermometers (thermostats) Automotive applications (to meas...
Infrared thermometers are divided into fixed thermometers and hand-held thermometers. They are a kind of thermometer that detects the amount of infrared rays on the surface of an object to achieve temperature measurement. How does an Infrared Thermometer work?
Liquid Expansion Thermometer A standard thermometer is usually a bulb or a spring thermometer. Both work by having a liquid, either alcohol or mercury, enclosed in a vacuum, and the liquid expands as the temperature rises. Colored alcohol or mercury rises along a scale in a bulb thermometer wh...
Apassive sensor, on the other hand, doesn't require an external power source to detect environmental input. It relies on the environment itself for its power, using sources such as light or thermal energy. A good example is the mercury-based glass thermometer. The mercury expands and contracts...
The simplest kind of barometer is a tall closed tube standing upside down in a bath of mercury (a dense liquid metal at room temperature) so the liquid rises partly up the tube a bit like it does in a thermometer. We use mercury in barometers because it's more convenient than using ...
How does a manual pyrometer work? You look through a telescope eyepiece, through a red filter (to protect your eyes), at the object you're measuring (typically through a spyhole set into a kiln or a Tuyère in a furnace—the nozzle where air is blown in). What you see is a dull ...
Semiconductor thermometer devices are often used in modern thermocouple instruments. In both cases the value V+E(Tref) is calculated, then the function E(T) is searched for a matching value. The argument where this match occurs is the value of Tsense. ...
