GD10L開放式紅外碳烴氣體探測儀
GD10L開放式紅外碳烴氣體探測儀,GD10L提供鍋爐廠到離岸石油化工裝置的氣體危害范圍的保護,廣泛應用于各種工業環境,對檢測到的氣體起到迅速和有效的反應。同時能夠及時保護生命和財產的**。
特性:
- Solid state optics – 15 years warranty on IR sources
- Easy alignment
- Tolerates misalignment more than conventional TX – RX systems.
- Alignment by a single person
- ATEX and IEC Ex approved
- Enhanced coverage
- Heated and Precision designed retro-reflector
The GD10L provides an effective response to the detection of gas hazards in a wide range of industrial environments from boiler plant rooms to offshore petrochemical installations.
The GD10L safeguards life, environment and property through reliable gas detection over path lengths from 2 (6.5 feet) to 30m (100 feet).
The IR sources are more resistant to vibration/shock than competing technologies, hence replacement of the IR sources is not necessary during it’s long service life.
The unit combines a transmitter / receiver into a single housing and utilises a novel retro-re?ector. The whole system can be commissionable by a single person.
The retro-re?ector is heated to minimise condensation and icing.
5 years warranty, 15 years on IR sources
