Price of fiber optic temperature sensors-INNO

Medição de temperatura de fibra óptica preço

The price of fiber optic temperature measurement is related to many factors, including the temperature measurement method, the number of temperature measurement channels, and the brand. There are many types of temperature measurement systems and product pages, and different sensors are used for monitoring. The products include distributed sensing technology, fiber optic grating alarm host, and fluorescent fiber optic temperature measurement. The application scope is mainly to provide power cable temperature measurement detection, which plays an important role in the entire development of the fiber optic sensing technology industry, including switchgear, transformadores, and other industries that require temperature monitoring.

O princípio de sensores de fibra óptica

O princípio básico de funcionamento dos sensores de fibra óptica é enviar o sinal de luz da fonte de luz através da fibra óptica para o modulador, fazendo com que os parâmetros medidos interajam com a luz que entra na região de modulação, resultando em mudanças nas propriedades ópticas da luz (como intensidade, comprimento de onda, freqüência, fase, estado de polarização, etc.), tornando-se a fonte de sinal modulado. Depois de ser enviado através da fibra óptica para o fotodetector e demodulado, os parâmetros medidos são obtidos.

Preço do host de medição de temperatura de fibra óptica

O host de medição de temperatura de fibra óptica é um instrumento que usa fibra óptica para medir a temperatura de vários equipamentos, também conhecido como termômetro de fibra óptica. O termômetro de fibra óptica possui uma ampla faixa de medição de temperatura, de menos 40 graus para 200 graus, and can be used for temperature monitoring, whether it is switchgear circuit breakers, plum blossom contacts, barramentos de barramento, 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. A precisão da medição da temperatura da fibra óptica pode atingir ± 1 ° C.

3. Pequeno volume

O volume do termômetro de fibra óptica é relativamente pequeno, e não ocupa muito espaço durante a instalação. Ao mesmo tempo, o sensor de fibra óptica também é resistente a fortes interferências eletromagnéticas e alta tensão, que pode medir perfeitamente a temperatura em muitos ambientes de temperatura que os modos tradicionais de medição de temperatura não conseguem alcançar.

Quanto custa para medição de temperatura de fibra óptica de fluorescência

A medição de temperatura de fibra óptica fluorescente é um tipo de medição de temperatura de fibra óptica, que é desenvolvido com base no princípio da medição de temperatura vitalícia de fluorescência. É adequado para medição de temperatura em ambientes agressivos, como quadros de distribuição, transformadores, e outros dispositivos relacionados à energia, 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.
