GAS SENSING SYSTEMS & TDLS OptoSniff-MPN, OptoSci's unique multipoint Tuneable Diode Laser Spectroscopy (TDLS) sensing system, continuously measures gas concentration levels at multiple points distributed along a passive optical fibre network. The system can routinely monitor for methane, carbon dioxide, water vapour, natural gas, and several other gases. The sensors never need re-calibration, and a single control unit can monitor up to hundreds of points, with full system update times of less than a second. OptoSniff-MPN offers continuous, multipoint gas sensing capability suitable for safety, explosion risk, environmental, and emissions monitoring; this makes OptoSniff-MPN ideal for applications in mines, tunnels and voids under buildings, landfill and brownfield sites, sewage and water treatment works, gas and petroleum installations, industrial process monitoring and control, etc. Standard Features General features of OptoSniff based systems are Constantly monitor hundreds of points over long (~10km) optical networks Sensor never needs re-calibration Full system calibration performed once at the central control unit (CCU) High gas sensitivity and wide measurement range Fast sensor response and rapid system update time (<1 sec) Single or multiple gases can be monitored with no gas cross-sensitivity Optical sensor network is intrinsically safe and immune to EMI All sensor data available at CCU Each sensor can tolerate over 90% signal loss Plug-in modules enable easy component replacement or system expansion Minimum maintenance requirement ensures low cost of ownership Some Continuous Multipoint Monitoring Applications Safety monitoring for explosive methane build up throughout mine tunnels Detection of gas main and natural gas leaks along tunnels and in voids under buildings Constant perimeter monitoring of methane and carbon dioxide on landfill sites Monitoring for gas collection under and in buildings constructed on brownfield sites Multipoint methane / carbon dioxide / water vapour detection at gas and petroleum installations Methane detection at several points in water treatment and sewage processing plants Water vapour sensing for industrial process monitoring and control Applications requiring multipoint monitoring of gases such as: methane, carbon dioxide, water vapour, natural gas, hydrogen fluoride, hydrogen chloride, acetylene, ammonia, etc. The following datasheets provide additional details on OptoSniff and some of its potential applications. When you have had an opportunity to review this information please contact OptoSci with your specific requirements and we will be pleased to discuss them with you in further detail. MMS Laser sensing system for single or multiple point continuous gas monitoring. Has applications in landfill sites, mines, gas and petroleum installations, industrial process monitoring, etc. MMS-L Laser sensing system for multipoint continuous methane monitoring on landfill sites. Applications include: continuous monitoring records, optimising engine efficiency, early warning system, safety level measurements, perimeter and gas migration monitoring. MMS-P Laser sensing system designed specifically for continuous perimeter and gas migration monitoring of methane and carbon dioxide on landfill sites. OEM While OptoSci can supply complete gas sensing systems we are also pleased to discuss and consider producing OEM OptoSniff sub-systems for integration into clients' own monitoring and control instruments, or custom systems designed to monitor other gases.
