I. What is a Fiber Bragg Grating Temperature Sensor? Basic Concept of FBG Temperature Sensor/Thermometer
A fiber bragg grating temperature sensor is a type of sensor that uses a fiber bragg grating (FBG) as a sensitive component and is combined with a fiber bragg grating demodulator (FBG analyzer) to detect and monitor the temperature of the measured object and its environment.
Fiber bragg grating temperature sensors are also known as FBG thermometers, fiber bragg grating temperature probes, FBG temperature probes, etc. From a product classification perspective, they belong to the category of fiber bragg grating sensors and are a type of optical fiber sensor. From a product functionality perspective, they belong to the category of temperature sensors.
II. Classification of Fiber Bragg Grating Temperature Sensors - FBG Temperature Sensor
1. Based on the temperature resistance level, FBG temperature sensors can be classified into high-temperature resistant, room temperature, and low-temperature resistant types.
2. Based on the number of FBG temperature measurement points encapsulated in the FBG temperature sensor, they can be classified into single-point FBG temperature sensors and multi-point FBG temperature sensors (series-connected FBG temperature sensors, quasi-distributed FBG temperature sensors), etc.
3. Based on the encapsulation material of the FBG temperature sensor, they can be classified into seamless steel tube FBG temperature sensors, ceramic FBG temperature sensors, polymer FBG temperature sensors, etc.
There are many other classification methods for FBG temperature sensors, and DCYS can customize different types of FBG temperature sensors. These are not further elaborated here...
III. Measurement Principle of Fiber Optic Grating Temperature Sensors - FBG Temperature Sensor
The measurement principle for temperature measurement and monitoring using FBG temperature sensors is as follows:
IV. Applications of Fiber Bragg Grating Temperature Sensors - FBG Temperature Sensor
FBG sensors are the most widely used type among all optical fiber sensors. They can be extensively applied in various independent temperature measurement environments, including temperature measurement, detection, and monitoring in mechanical and electrical products, industrial production, petroleum and petrochemical industries, power, railways, military, aviation, aerospace, metallurgy, chemical engineering, and other fields. They can also be used for temperature compensation with various other optical fiber sensors. DCYS does not further elaborate on this...

Here are physical videos of commonly used FBG temperature sensors produced by DCYS:
VI. Models and Parameters of FBG Temperature Sensors
1. DCYS produces the OFSCN® Capillary Seamless Steel Tube series of FBG temperature sensors. These sensors use the company's proprietary "stainless steel seamless tube packaging technology" to package the FBG. They have various models.
The product structure is very simple and can encapsulate single-point fiber bragg grating (FBG) or fiber bragg grating strings/arrays (FBGs, quasi-distributed). They can be used to encapsulate UV photomask FBG, femtosecond laser point-by-point written FBGs, as well as drawn tower direct-written FBGs.
The FBG temperature sensors designed by DCYS have a maximum operating temperature range of -200℃ to 1000℃, making them resistant to both low and high temperatures. The standard product sizes are 0.9mm/2.0mm/3.0mm, with the smallest diameter being 0.5mm and the minimum weight per meter being 1.8 grams. They achieve the characteristics of being "capillary". The tensile strength of standard products ranges from 200N to 3000N, and the compressive strength ranges from 70MPa to 200MPa.
Due to the special encapsulation materials used in the Capillary Seamless Steel Tube series FBG temperature sensors, which provide excellent mechanical properties, they can be conveniently placed on the surfaces of various objects, as well as in underwater environments, corrosive environments, flame environments, etc. This greatly expands the range of applications for FBG sensors.
2. DCYS also uses other materials to package FBG temperature sensors, such as using the company's proprietary polymer materials to encapsulate FBGs, using the company's proprietary seamless steel tube nested polymer materials to encapsulate FBGs, and using commonly used ceramic tubes to encapsulate FBGs, providing insulation properties.
3. DCYS can also customize FBG temperature sensors with different structures according to customer requirements.
VII. Key Points and Main Parameters for Selecting FBG Temperature Sensors
DCYS offers a wide range of the "OFSCN®" series FBG temperature sensors, and there are many models to choose from. When making your selection, consider the following:
1. Determine the temperature you need to measure. Once you have determined the required temperature range, you have already confirmed the fiber bragg grating (FBG) you will need.
2. Determine the number of temperature measurement points. Is it a single-point or multi-point temperature measurement? If it's multi-point, confirm the number of FBGs required for one sensor.
3. Consider the operating environment. Do you need insulation? This will determine the armor layer of the FBG temperature sensor, whether it is seamless steel tube armor, low-voltage insulated armor, or fully insulated ceramic armor.
4. Determine the sensor installation method. Once you have determined the sensor installation method, you can determine whether a customized sensor structure is required. DCYS has extensive experience in customizing FBG temperature sensors for various applications.
VIII. Pricing of FBG Temperature Sensors
After providing DCYS with information such as the required temperature range, number of measurement points, and installation method, another important piece of information to clarify is the quantity you need to purchase.
As a manufacturer, the price of FBG temperature sensors from DCYS is directly related to the quantity you purchase. The price of FBG temperature sensors mainly includes material costs, production labor costs, and calibration service fees. The production labor costs and calibration service fees decrease rapidly as the production quantity increases, resulting in a rapid decrease in unit price.
