Advantages and application range of fiber optic temperature sensors-INNO

Perkembangan penderia suhu has become very common in China, and there are many types of sensors used in the field of temperature measurement. When monitoring temperature and pressure parameters below oil wells, electronic sensors such as PT100 have the characteristics of high measurement accuracy, intuitive display methods, and reliable data acquisition, making it one of the most widely used downhole measuring instruments. The disadvantages of electronic sensors are also very obvious, because electronic temperature sensors are usually assembled from electronic components, with relatively large circuit board sizes, short lifespan, easy damage, and susceptibility to external interference. The depth of entry into oil and gas wells is limited, and they can operate at low temperatures for a long time; Penderia elektronik ialah peranti hidup aktif yang menimbulkan bahaya keselamatan penyalaan elektrik dalam persekitaran bawah tanah yang mudah terbakar dan mudah meletup.

Teknologi penderiaan gentian optik ialah teknologi penderiaan baharu yang telah mengiringi pembangunan gentian optik dan teknologi komunikasi gentian optik. Ia merupakan teknologi aplikasi berteknologi tinggi yang paling pesat membangun di peringkat antarabangsa sejak pertengahan abad ke-20.

Pada masa ini terdapat dua jenis utama teknologi penderiaan gentian optik di pasaran, seseorang menggunakan gentian optik sebagai penderia secara langsung, dan satu lagi adalah berdasarkan penderia parut. Penderia gentian optik pada asasnya berbeza daripada penderia berasaskan elektrik. Penderia gentian optik menggunakan cahaya sebagai pembawa maklumat sensitif dan gentian optik sebagai medium untuk menghantar maklumat sensitif, making them widely used due to their unique characteristics.

Pengukuran suhu gentian optik technology is a new technology that has only recently developed. The advantages of fiber optic temperature sensors include: tiada gangguan elektromagnet, rintangan kakisan; Passive real-time monitoring, penebat elektrik, and good explosion-proof performance; Saiz kecil, ringan, and can be bent; High sensitivity and long service life; Long transmission distance and convenient maintenance.

The application range of fiber optic temperature sensors is quite extensive. It uses optical fibers as the optical path to separate the probe from the instrument, increasing its adaptability to the environment. It can measure under conditions such as strong electromagnetic interference, voltan tinggi, and the inability to use leads for electrical transmission. Pada masa ini, the successfully developed sensors mainly include fluorescent fiber temperature sensors, birefringent crystal sensors, dan sensor semikonduktor. Most existing fiber optic temperature sensors are independently developed based on different spectral analysis principles.

Sensor suhu gentian optik is a rapidly developing temperature measurement technology, which pre modulates the light incident into the fiber optic and then enters the field to be measured for optical and physical properties changes. Based on the characteristics of the changed light, phase modulation, polarization modulation, or distributed temperature sensors are made. Fiber optic temperature sensors are divided into two types based on the medium and method used for temperature measurement: non transmission type and transmission type. Fiber optic temperature sensors have good electrical insulation and anti electromagnetic interference capabilities. They are passive devices that do not affect the measured object. Selain itu, the size of the temperature measuring element is small, corrosion-resistant, and especially safe and reliable in flammable and explosive environments.

Common non transmission penderia suhu gentian optik include distributed fiber optic temperature sensors using Raman scattering mechanism and optical time-domain reflection technology, Fabry interferometer fiber optic temperature sensors, and fiber optic grating temperature sensors.

How to pilih penderia suhu gentian optik and what is the price of fiber optic temperature sensors

It is rarely used in daily life, but fiber optic temperature sensors are often needed in industry, such as transformer temperature measurement in the power industry, gentian optik teragih temperature measurement in cables, precision instruments, and fluorescent fiber optic temperature sensors in medical equipment. So what are the characteristics that a high-quality sistem pengukuran suhu gentian optik must have.

1. Accurate temperature measurement data

The temperature data obtained through monitoring with fiber optic temperature sensors must be accurate, rather than being affected by external factors that may cause temperature values to deviate. As many measured objects require precise temperature measurement, excellent fiber optic temperature measurement equipment must be able to make accurate judgments through the fiber optic temperature sensor probe, without significant temperature errors or interference.

2. Temperature measurement of multiple different products

In addition to common pengukuran suhu pengubah, there are also reactors, pemutus litar, kabel, and other products that require pengukuran suhu gentian optik. Oleh itu, fiber optic temperature measurement equipment cannot only measure the problems of a single product. The products that can be detected must have a wide range, which can effectively save the cost of temperature sensors.

3. Adapt to different temperature measurement environments

Many temperature measurement environments contain electromagnetic interference, strong currents, kakisan, dll. Good fiber optic temperature sensors can have excellent performance for different temperature measurement environments. Poor temperature measurement conditions cannot affect the temperature measurement accuracy and stability of fiber optic temperature sensors. Penderia suhu gentian optik pendarfluor can adapt to different environments and are reasonably priced.
