Xuhai supplies a comprehensive device/module-in-set solutions for customers based on TDLAS technology to detect explosive and poisonous gases. We supply laser, gas cell, PD,laser point sensor assembly and remote detection assembly to three detection systems such as on-line laser point sensor type system, fiber distributed type on-line detection system and laser remote detection system.
Laser gas detection shows advantage in long product lift(5-10years), no maintenance/calibration and no false alarm compared with sensors based on other technologies.
Xuhai only supplies whole set of components and modules to Mathane(CH4) and Oil Gas(C3H8) detection now. For H2S,CO,NH3 and O2 gas sensors based on TDLAS technology, Xuhai’s product will come out in June,2020.
Multiple Channels Fiber Distribution Type On-Line Gas
Detection System
Distribution type detection system has two advantages:
1) Multiple(32pcs) optical passive
detectors can share one laser which can reduce cost of components.
2) Passive detection without power supply and electrical signal in testing point site
But distribution type has high fiber deploying cost and low security. Because if the laser doesn’t work, the whole system fails to work. But customers can delploy a backup laser to prevent such situation.
Though this system need deploy fibes resource which will trigger cost increase because of fiber deploying, for comprehensive pipe and coal mine site, its fibers resource need to be deployed whether you will install this system or not. So the total cost is low for such special condition. If customers is not senstive to deploying cost or the testing site need purely passive detection, fiber distribution type is the best choice.
Laser Point Type Gas Detection System
Compared with Fiber distribution type, laser point type shows advantages in items listed as below:
1) low cost in deploying cost; 2) high security (every sensor can work individually) 3) Easy to integrated into IOT
But Laser point type has higher cost because each testing point need one
laser each. Xuhai can supply flexible solution (components, assembly or
modules) for laser point gas type detection system. Xuhai can supply laser, gas
cell, PD, optical assembly and whole laser point gas sensor to customer based
on customers’ requirement.
The point gas sensor without refernece gas cell is avaliable. The
product with reference gas cell can also be developed based on customer’s
requirement.
Laser
Remote Type Gas Detection System
Laser Remote Type detection
system shows advantages in items listed as below:
1) Portable(Small Package) ; 2) Long detection Distance without people’s reaching the place ; 3) Fast response
Laser remote type gas detection is
suitable for manual/vehicle/UAV patrol of gas leakage. Xuhai can supply
flexible solution (components or assembly) for laser remote type gas detection
system. Xuhai can supply laser, laser remote optical assembly to customer based
on customers’ requirement.
