Description

Traditional sensors are mainly electrical sensors, and electrical signals are the carrier of changes in external parameters. Various technical and application bottlenecks have gradually appeared. Fiber grating sensing systems are resistant to electromagnetic interference, intrinsically safe, small in size and light in weight. It can be reused on a large scale and has the incomparable advantages of electrical sensors. It is very suitable for long-term monitoring in harsh environments such as flammable, explosive, strong electric and magnetic, and unattended: temperature, strain, pressure, displacement, vibration, acceleration,etc. 

Founded in Shenzhen in 2007, Dimension has developed into a global leading optical testing solutions provider with the spirit of "imaging, acting, innovating and leading", providing first-class optical device testing and fiber endface inspection solutions and equipments.

Dimension can also provide customized services according to the special needs of customers.

2.Main advantage

• Intrinsic safety: The optical fiber sensor itself is made of glass, which is anti-electromagnetic interference, safe, explosion-proof, corrosion-resistant, and has good chemical stability

• Large-scale networking: Based on the optical wavelength division multiplexing technology, multiple fiber grating sensors can be connected in series on a fiber to measure different physical quantities (such as temperature, strain, displacement, pressure and other physical quantities), and share one signal Demodulation equipment to form a large-scale sensor monitoring network;

• Small size, light weight, long transmission distance up to 60KM or more; 

• Long life, the sensor design life can reach 8-20 years, suitable for long-term health monitoring of bridges, tunnels and large buildings;

• Professional optical fiber sensing team can provide flexible and innovative customized solutions according to customer requirements.
