no contact thermometer
A thermometer is a device used to measure temperature.
There are different types of this device, each of which is used for specific applications.
Thermometers are used in a wide range of industries from medicine to home air conditioners and industry.
Thermometers are divided into different types, each of which has a different way of working.
Types of thermometers
- Mercury thermometer
- Alcohol thermometer
- Digital thermometer
- Laser thermometer
The first 4 are all contact thermometers.
This means that the temperature can not be measured remotely and the thermometer must be inserted into the environment or close to the environment.
There are other types of thermometers known as laser thermometers or laser thermometers.
These thermometers work by sending a wave of infrared (IR) light that strikes the object.
As a result of this collision, according to the temperature of the body, the energy of the reflected rays changes, which can be measured to obtain the temperature of the body.
These types of thermometers, because they can be used remotely, have found many applications in cases where it is not possible to approach the heat source.
One area that uses thermometers a lot is medicine.
In this area, the working temperature of the cells of the human body is very effective in its function. With very little change in the temperature of the cells, it can lead to very drastic changes in the function of the body.
A laser thermometer is actually an infrared thermometer.
We know that hot air molecules and hot bodies are more active than other objects.
These molecules produce an infrared energy that is absorbed by a laser thermometer and converted into an electrical signal.
A laser thermometer displays the temperature of all objects and converts it into an electrical signal to display the temperature on the screen.
Infrared energy has a longer wavelength than visible light and causes, except for the spectrum of electromagnetic waves such as microwaves, radio waves; Ultraviolet and X-rays.
What is the basis of laser thermometer?
The laser thermometer works by concentrating infrared energy at one point through built-in lenses and mirrors, and by measuring energy and converting it into an electrical signal, it can measure the temperature of an object without contact up to a distance of 50 meters. he does.
In addition, the temperature of moving objects can be measured, and this model of laser thermometers is the only device that gives us the most accurate body temperature, ie with an accuracy of about 2 و and ℉ 4 the most accurate error in Between thermometers.
Laser thermometers are offered in single-laser and dual-laser models for ease of measurement and reduction of operator vision errors in multi-measurement equipment.
Laser thermometer / non-contact thermometer
Used to measure temperature from a distance.
Laser thermometers use infrared sensors and are also known as laser thermometers.
By knowing the amount of infrared energy emitted from the body, the temperature of the object can be measured with a laser thermometer.
The portable type of these laser thermometers is known as a gun thermometer and is used in the laboratory.
A laser thermometer is used to sample and record the temperature of objects from a distance.
Some laser thermometers also have the ability to install a probe to measure temperature by contact method, which are called dual-function thermometers.
- Dual laser gun thermometer
- Single laser gun thermometers
- Laser thermometer with the ability to connect to a computer – data logger
- Digital infrared thermometer
- Laser thermometer for refrigerators and food refrigerators and thermal leaks
- Waterproof gun thermometer
- Three-function contact thermometer – non-contact (infrared) – clamp
- Laser thermometer with flexible probe
One of the important quantities that is of special importance in industrial units is the system temperature.
For this purpose, various devices are used that according to the need, in addition to measuring the temperature, often have the ability to generate a control signal as well as a switch.
Temperature measurement methods can be classified into contact and non-contact.
The contact method actually uses the contact of a sensor, which can be a thermocouple or thermoresistance (PT100).
This measurement method in most analog models is done by bimetal or gas-filled method, which is made of a bubble and capillary tube, which is known as a gas thermometer or thermometer.
The non-contact measurement method is mostly based on the amount of infrared radiation that the target object emits to the environment.
These thermometers are known as shotguns or thermometers.
The reason for using the word laser is to use a laser beam of light to identify the target.
Temperature is measured in degrees Celsius, and in some countries where other scales, such as Fahrenheit, are very common, the Kelvin scale is also commonly used in physical equations.
