Company Introduction

Anhui Tiankang (Group) Co., Ltd. was founded in 1974, headquartered in Tianchang City on the banks of the Yangtze River. It is adjacent to the ancient city of Nanjing to the south and Yangzhou to the east. Located in the vibrant "Yangtze River Delta" economic circle, it has a favorable investment and development environment. After more than 30 years of development, the instruments, cables, optical cables, pharmaceuticals, scientific research, new energy, wood industry, steel pipes and other products under the group company have been widely used in industries such as petroleum, power, chemical, communication, and health due to their good quality and service. The company has now become a contract abiding and trustworthy enterprise, a key backbone enterprise in 50 households in Anhui Province, an enterprise that pays taxes in accordance with the law in Anhui Province, a bank credit AA enterprise, a Chinese electronic component and instrument enterprise, and one of the top 20 Chinese wire and cable enterprises.

Product Overview

The products include various fiber Bragg grating sensing product series such as temperature, strain, pressure, displacement, acceleration, and optical sensing network analyzers, with product performance reaching the industry level. The product can be widely used for real-time and distributed health monitoring of bridges, civil and industrial buildings, dams, transmission pipelines, power facilities, offshore oil platforms, and other large-scale architectures. These products uphold all the inherent excellent characteristics of fiber optic sensors, including intrinsic safety, electromagnetic interference resistance, corrosion resistance, high temperature resistance, and long service life; In terms of application, our company has its own technical characteristics, and each product series has strong networking capabilities. Different series of products can be mixed and networked freely, and can be equipped with the same demodulation equipment, providing customers with simple and complete technical solutions.

(1)Surface type fiber Bragg grating temperature sensor

The FBGT series fiber Bragg grating has the advantages of quasi distributed networking (hundreds or thousands of points), high temperature measurement accuracy (0.1 ° C~0.5 ° C), wide temperature measurement range (-100 ° C~+300 ° C), no zero drift, no electromagnetic interference, corrosion resistance, impact vibration resistance, and long service life. It can be divided into various packaging structures such as surface type, buried type, and immersion type, and can be widely used in large-scale structures such as bridges, dams, oil and gas pipelines, offshore oil platforms, as well as large-scale facilities or equipment in the fields of construction, medicine, chemical industry, power, aerospace, fire protection, mining, etc. for quasi distributed precise temperature measurement.

(1)Surface type fiber Bragg grating temperature sensor

Widely applicable for measuring the surface temperature of steel structural components, concrete, and other components. It can also be used as an optional accessory for temperature compensation of all surface strain sensors.

It can be divided into various packaging structures such as surface type, buried type, and immersion type, and can be widely used in large-scale structures such as bridges, dams, oil and gas pipelines, offshore oil platforms, as well as large-scale facilities or equipment in the fields of construction, medicine, chemical industry, power, aerospace, fire protection, mining, etc. for quasi distributed precise temperature measurement.

（2） Embedded fiber Bragg grating

Embedded fiber Bragg gratingtemperature sensorThe temperature value is detected by the central wavelength shift of the light signal reflected by the internal sensitive component - fiber optic grating. The temperature measurement accuracy and resolution are not affected by the fluctuation of the light source and the bending loss of the transmission line. The signal can be directly transmitted remotely through the fiber optic cable (over 40km), and there is no need for power supply at the monitoring site. Sensors have various packaging structures such as surface mounted, embedded, and immersed, and can be widely used for quasi distributed precise temperature measurement of large structures such as bridges, dams, oil tanks, oil and gas pipelines, tunnels, grain depots, factories, offshore oil platforms, as well as large-scale facilities or equipment in the fields of medicine, chemical engineering, power, aerospace, fire protection, mining, etc.
