Price of fiber optic temperature sensors

Fiber optic temperature measurement price

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, transformers, and other industries that require temperature monitoring.

The principle of fiber optic sensors

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 (such as intensity, wavelength, frequency, phase, polarization state, etc.), becoming the modulated signal source. After being sent through the fiber optic to the photodetector and demodulated, the measured parameters are obtained.

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 degrees, 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. So, 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 wireless temperature measurement, including the best fiber optic temperature measurement method currently used.

2. High temperature measurement accuracy

The most important thing for instruments and equipment is to accurately detect data. If there is a large error, it will appear worthless. However, 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. At the same time, 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 fluorescence fiber optic temperature measurement

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, transformers, and other power related devices, as well as medical, battery, 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.

Price of distributed fiber optic temperature measurement system

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. This distributed fiber optic temperature measurement system is widely used by many large construction and subway companies, greatly reducing the occurrence of various fire accidents. In addition, 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.

Price of Fiber Bragg Grating Sensors

Fiber Bragg grating (FBG) is a passive optical device with a periodic refractive index change in the fiber core. It has the characteristics of anti electromagnetic interference, flexible structure, fiber compatibility, wavelength coding, simple and easy demodulation of spectral lines, strong multiplexing ability, simple structure, convenient production, and compact size. It has been widely used in the field of fiber optic sensing and communication. Fiber Bragg Grating has the characteristics of easy connection with optical fibers, low transmission loss, good spectral characteristics, and high reliability. Fiber Bragg Grating, as a sensing element, can achieve high-capacity, distributed dynamic monitoring of physical quantities through wavelength modulation. It can effectively overcome the shortcomings of traditional electrical sensing technologies and measurement systems in long-term stability, environmental adaptability, and distributed sensing detection. It can effectively measure physical quantities such as temperature, strain, vibration, and pressure, and is widely used in health monitoring in fields such as bridges, tunnels, dams, power stations, oil tanks, and mechanical equipment, greatly meeting the physical quantity measurement requirements of military and civilian applications.
