As you know, the main prerequisite for doing anything is to have proper information about that subject. In order to choose, review the prices, buy and know more about thermometers, the following contents are included so that you, dear visitors of the specialized website of Damatajhiz, can use these information to choose and buy different types of laser, digital and pointer thermometers from Vika, Pickens, Bentec, TJ, Delta Control, Wilmer, Beta, etc. brands in bulk.
Introduction and user manual of thermometer or thermometer
A thermometer is a device for measuring temperature, which has different types based on its use. Thermometers are used in package heating and cooling facilities, small and large engine houses, and various industries. Note that when buying the required thermometer, in addition to paying attention to the type of thermometer, pay attention to the temperature range and type of connection (sheath from the bottom, sheath from the back), the length of the sensor sequence (sheath), the size of the screen and the required brand. Join us in introducing and checking the performance of different types of thermometers in the rest of this article (for wholesale purchase).
The most important types of thermometers in industry and facilities
Laser thermometers
Digital thermometers
Stick thermometers
Dial thermometers
Non-metal thermometers
Gas thermometers
Mercury thermometers
Thermocouples
Dial thermometer
Dial thermometers have the following types:
Bimetal thermometer
Actuated thermometer
Hand thermometers have different types in terms of length, material, and types of sensor connection, such as sheath from below, sheath from the back, and sense (tail) with different lengths.
Actuated types of thermometers
A thermometer filled with mercury to measure pressure
Liquid-filled thermometer to measure pressure
Thermometer to measure steam pressure
Thermometer to measure gas pressure
Non-metal thermometer
In a non-metal thermometer, two different metal strips are used to convert temperature changes into mechanical changes. Usually, two metal strips are copper and steel or steel and brass. Based on the amount of expansion and bending of the tape by the temperature changes, a hand moves on the graduated plate and shows the temperature. Usually, to increase the sensitivity, the metals' length is increased and assembled as a spring.
Gas thermometer
In a gas thermometer, the temperature is measured using changes in volume or pressure. This thermometer consists of a glass, quartz, porcelain, and platinum bubble (the bubble type varies depending on the temperature range used). This bubble is connected to a pressure gauge or mercury manometer by a capillary rod.
Types of gas thermometers
Gas thermometer with constant volume
Constant pressure gas thermometer
Mercury thermometer
These thermometers work with mercury and show the temperature based on the change in mercury volume (contraction or expansion). This type of thermometer is used in various industries, including medical affairs, to measure a patient's fever.
Alcohol thermometer
This type of thermometer works with alcohol, and like mercury thermometers, the amount of contraction or expansion of alcohol indicates the temperature on the graduated tube of the thermometer. Alcohol thermometers are used in laboratories and have a temperature range of 0 to 100 degrees Celsius. One of the advantages of the alcohol thermometer compared to the mercury thermometer is the low risk of alcohol toxicity.
Bar thermometer/thermometer
These thermometers are used for purposes where there is a need to insert the thermometer rod into the object to measure the temperature. One of the applications of the stick thermometer is to measure the temperature of food and liquids in the food industry.
Digital thermometer
This type of thermometer has a semi-conductive sensor that changes its resistance as the temperature changes. As a result, the current passing through it also changes, and in this way, they measure the temperature of the environment. These thermometers are used in refrigerators, ovens, coolers, etc.
Thermocouples
On thermocouples, two different metals are connected. As a result of temperature change, a potential difference is created between these two metals, and the amount of this potential difference indicates the temperature. For example, this thermometer or thermometer is used to measure the temperature inside the oven.
Laser thermometer (infrared thermometer - IR thermometer)
, Unlike other thermometers we introduced, the laser thermometer measures the temperature in a non-contact manner. In this way, they emit infrared or infrared (IR) rays toward the material. After the waves collide with the object, they measure the energy of the return beam, and this energy difference in the return beam indicates the temperature of the desired object. Will be. These thermometers are widely used due to their non-contact nature and the possibility of remote temperature measurement.
One of the common uses of laser thermometers is to use them as thermometers in public places.
Thermometer-Manometer
Thermometer-manometer is a device that can measure temperature and pressure. In thermometer-manometers, there are two semi-circles separated from each other. One of the pointers shows the temperature, and the other shows the pressure division of thermometers and manometers based on diameter, size, temperature range, and pressure range, as well as types of sheaths from the back and sheaths from below.
