Existem muitos tipos de sistemas de medição de temperatura e páginas de produtos, e diferentes sensores são usados para monitorar. Os produtos incluem tecnologia de detecção distribuída, host de alarme de grade de fibra óptica, e medição de temperatura de fibra óptica fluorescente. O escopo da aplicação é principalmente fornecer detecção de medição de temperatura do cabo de alimentação, que desempenha um papel importante em todo o desenvolvimento da indústria de tecnologia de detecção de fibra óptica, incluindo aparelhagem, transformadores, e outras indústrias que exigem monitoramento de temperatura.

O princípio de sensores de fibra óptica

The basic working principle of fiber optic sensors is to send the light signal from the light source through the fiber optic into the modulator, causing the measured parameters to interact with the light entering the modulation region, resulting in changes in the optical properties of the light (como intensidade, comprimento de onda, freqüência, fase, estado de polarização, etc.), becoming the modulated signal source. After being sent through the fiber optic to the photodetector and demodulated, os parâmetros medidos são obtidos.

Price of fiber optic temperature measurement host

Fiber optic temperature measurement host is an instrument that uses fiber optic to measure the temperature of various equipment, also known as fiber optic thermometer. The fiber optic thermometer has a wide range of temperature measurement, from minus 40 degrees to 200 graus, and can be used for temperature monitoring, whether it is switchgear circuit breakers, plum blossom contacts, busbar busbars, and power equipment such as dry-type transformer temperature measurement and oil immersed transformer winding fiber optic temperature measurement. It is an essential instrument in factories and some power industries.

The use of fiber optic temperature sensors is very widespread. Então, what are the reasons why they can be widely used in industries such as rail transit? Is it because we do have a need to use them or because they have inherent value that we have to use them? To be honest, these reasons all exist. We need to monitor whether the actual temperature of various equipment during operation meets our needs.

1. Essential products in the temperature measurement industry

There are many devices in the power industry that generate temperature rise during operation, so the requirements for temperature measurement are relatively high. If temperature detection is carried out in power equipment, temperature measurement equipment is needed. In addition to the traditional PT100 platinum resistance temperature measurement, there are also infrared temperature measurement and medição de temperatura sem fio, including the best fiber optic temperature measurement method currently used.

2. Precisão de medição de alta temperatura

The most important thing for instruments and equipment is to accurately detect data. If there is a large error, it will appear worthless. No entanto, if the test is accurate, we can further determine whether the instrument is operating within a controllable temperature range. The accuracy of fiber optic temperature measurement can reach ± 1 °C.

3. Small volume

The volume of the fiber optic thermometer is relatively small, and it does not take up a lot of space during installation. Ao mesmo tempo, the fiber optic sensor is also resistant to strong electromagnetic interference and high voltage, which can perfectly measure temperature in many temperature environments that traditional temperature measurement modes cannot achieve.

How much does it cost for medição de temperatura de fibra óptica de fluorescência

Fluorescent fiber optic temperature measurement is a type of fiber optic temperature measurement, which is developed based on the principle of fluorescence lifetime temperature measurement. It is suitable for temperature measurement in harsh environments such as switchgear, transformadores, and other power related devices, as well as medical, bateria, and military environments. The price of fluorescent fiber optic temperature measurement systems is closely related to the number of temperature measurement channels. Power transformers play an important role in the power system, and their safe operation directly affects the reliability and safety of power supply. Statistics show that insulation damage is the main cause of transformer failures, and the winding is the part with the highest failure rate. The accuracy and real-time performance of temperature and deformation detection of windings are of great significance for the safe operation of transformers.

Preço de sistema distribuído de medição de temperatura de fibra óptica

Distributed fiber optic temperature sensors are mainly used for long-distance temperature measurement. The distributed fiber optic temperature measurement system can monitor the temperature of the measured object in real time. It can not only detect the occurrence of fire events in real time, but also provide accurate fire location, which saves time for immediate firefighting and minimizes accident losses. The system adopts a passive temperature measurement method with all fiber optic sensing, eliminating the safety hazards of the monitoring system itself and greatly improving the usability of the monitoring system for temperature monitoring of temperature objects. Esse sistema distribuído de medição de temperatura de fibra óptica is widely used by many large construction and subway companies, greatly reducing the occurrence of various fire accidents. Além disso, distributed fiber optic temperature measurement systems also have important and extensive application prospects in fields such as geothermal development and application, oil and gas extraction, and chemical production.
