An Introduction to the Construction Principle of Optic-thermometry

Optic-thermometry, or the measurement of heat through light, is a fascinating and useful optical instrument used to monitor and control temperatures in a variety of industrial and commercial settings. In this article, we will explore the fascinating construction principles of optic-thermometry, and why this technology is so important.

Optic-thermometry works by using a high-precision optical device, known as a thermal detector. This device is placed behind an objective or lens and then an infrared light is shone through the objective or lens onto the thermal detector. The thermal detector then detects the heat of the temperature object in question and then it is processed into a numerical form. The output from the thermal detector is then used as an input to a computer or controller, which can then be programmed to control the temperature of the object.

The construction principle of a thermal detector consists of several parts. The first is the detector itself, which is usually made of a special material that is highly sensitive to changes in heat. This material can come in various shapes and sizes, depending on the application and the sensitivity of the detector. The second part is the lens or objective, which can be made of several lenses or of one large lens, depending on the size and type of application.

The objective or lens is then positioned in front of the thermal detector and a light is shone through it to create a beam of infrared light. The thermal detector then absorbs some of the infrared light and converts it into an electrical signal. This signal is then used to measure the temperature of the object in question.

Optic-thermometry is used in many different industries, such as food and beverage processing, cooling and heating, automotive and aerospace industries, among others. In addition to temperature measurement, optic-thermometry can also be used to determine the water levels in storage tanks or to monitor air or water quality in industrial applications.

Optic-thermometry is a great device for monitoring temperatures in a wide variety of circumstances and is used in many different industries. It is an extremely accurate and reliable way to control the temperatures in industrial and commercial settings. The construction principle of a thermal detector is highly sophisticated and provides accurate and reliable temperature measurement. It is an essential part of any industry or application, as it can be used to ensure the safety and efficiency of operations.

The construction principle of optical high-temperature meter is based on the principle of optical pyrometer, which is a device used to measure high temperature. It is a non-contact temperature measurement method. This instrument is sensitive to heat radiation emission of hot objects, and can measure the temperature of hot objects accurately and quickly.

The working principle of the optical high temperature meter is based on the principle that when an object is in a thermal equilibrium state, the amount of heat radiation emitted by the object is proportional to the fourth power of its absolute temperature. By measuring the intensity of the thermal radiation at different wavelengths, the temperature of the target object can be calculated.

The optical high temperature meter is composed of a sensor, a data acquisition box, and a data display device. The sensor consists of a lens, a filter, a monochromator and a photodiode. The lens is used to collect radiation and focus the radiation onto the filter. The position of the filter is adjusted until it passes the radiation with the wavelength of interest and reflects the behind. The monochromator then refines the reflected light to produce a strong monochromatic beam to illuminate the sensitive surface of the photocell.

A photodiode is then used to detect the thermal radiation and convert it into an electrical signal, which is sent to the data acquisition box. The data acquisition box processes, amplifies and converts the signal, and sends the data to the data display device for display.

Therefore, the optical high temperature meter uses the principle of optical pyrometer to measure the temperature of objects. It is characterized by non-contact measurement, accurate measurement, fast response and good stability. It is widely used in industrial, military and scientific fields.
