Question: How many types of thermometers and how to select them?
Answer: Thermometers for industrial use have 4 main types.
1. Liquid or gas-filled thermometers use a gas or liquid as the temperature-sensing element.
2. Bimetal or bi-metallic thermometers use a bimetal spring as the temperature-sensing element.
3. Electronic devices such as thermistors measure changes in electrical resistance and convert them to changes in temperature.
4. Infrared thermometers are non-contact devices that convert infrared (IR) energy to an electrical signal that can be displayed in units of temperature.
We should select the thermometer following factors, Measurement range, Application, and Operating Environment.
Question: Infrared thermometer, how to choose to use it properly?
Answer: Infrared thermometers are often used to measure the surface temperature of materials. Infrared thermometers measure temperature by the heat radiation emitted by an object. No need to contact with target object from a distance. Therefore, suitable for choosing to measure in the area hard-to-access area (such as overheating area or inside machinery)
Question: Which is the better digital or analog thermometer?
Answer: Analog and digital thermometers do the same job. However, they are very different. The different characteristics make both types suitable for different applications.
The advantages of analog types of thermometers are that they are cheap, easy to read, can be submerged in liquids, require very little maintenance, and are reliable. The disadvantages are that they break easily and there is a risk of mercury poisoning if the glass tube breaks.
On the hand, The advantages of digital thermometers are that they are easy to read, require very little maintenance and give an accurate reading. The disadvantage is that they get damaged easily if dropped and cannot use without the battery powering them.
Question: How Infrared Thermometers work
Answer: An Infrared thermometer measures both infrared radiation and the emissivity value of a surface. The infrared thermometer has a lens that focuses the infrared rays and tunnels them through the thermometer to a detector known as a thermopile. Then, the thermopile converts the incoming Infrared radiation into an electrical signal that is then displayed as digital units of temperature.
Question: How accurate of infrared thermometers?
Answer: Industrial infrared digital thermometers have an error factor that averages around ±1 to 1.5°C, which is more than satisfactory for most industrial applications.
