Sampling Systems

Single Point Sampling
  • Compact and self-contained.
  • Monitors up to four gases continuously from a single point up to 1 km away.
  • The sample air inlet includes dust/water filters and a water barrier to cope with wet or dirty samples.
  • Typical applications include methane monitoring in pipelines and hydrogen sulfide monitoring in bio-scrubbers.
Four Point Sampling
  • Continuous independent monitoring of 2,3 or 4 sample lines
  • Wide range of sensors available
  • Sample lines can be up to 1Km in length
  • Each sample inlet contains dust and moisture filters with self-cleaning operation
  • Option for 'back-purge' facility to clear blockages from sample lines
  • Built - in Gasmaster to provide gas level display and relay outputs from all sensors
PGSi Programmable Sample System  
  • Sequential monitoring of up to 32 sample points
  • Can monitor up to 4 gas sensors
  • Sample lines can be up to 1Km in length
  • Contains dust and moisture filters with self cleaning operation
  • Option for 'back-purge' facility to clear blockages from sample lines
  • All functions are controlled using an industrial PC, which provides tabular, graphical or site-mimic displays of all gas readings and fault status, as well as data logging facility
  • Optional modem to dial-out on alarm, and provide remote interrogation facility
  • Configurable relay outputs
Environmental Sampling  
  • For cost-effective monitoring of 'heavier than air' gases such as chlorine and flammable vapors
  • Can monitor up to 12 meters of perforated pipe using a fan-aspirated single sensor
  • Ideal for use in areas such as LPG and chlorine stores, and wet wells in sewage pumping stations
  • Flameproof fan available for flammable gas applications
  • Fan-fail monitoring is available for up to four units using the Crowcon Fanmaster
Duct Monitoring  
  • Monitors gas levels in ducting where either the ducts are too small to accommodate a detector or the airflow levels are too high for accurate readings
  • Simple unit that is easy to fit
  • Extremely reliable as it has no moving parts
Aspirator Air-Driven Sampling  
  • Remote system to allow monitoring of flammable gas at installations operating at very high temperatures
  • Extracts a continuous stream of sample air from a remote position (for instance a turbine enclosure) and delivers it to gas detectors
  • Extremely reliable in operation and virtually maintenance-free as there is no need for a mechanical pump to deliver sample air
Vortex 8 Point Sampling  
  • Sequential monitoring of up to 8 sample points
  • Can monitor up to 4 gas detectors
  • Sample lines can be up to 1Km in length
  • Contains dust and moisture filters with self cleaning operation
  • Option for 'back-purge' facility to clear blockages from sample lines
  • Built-in Vortex unit to display gas levels and provide outputs via relay and RS-485 Modbus interfaces
Mill-Gard Coal Mill C.O. Detection System  
  • Can monitor 1 to 15 separate mill sampling probes
  • High flow pumps provide fast response
  • Conditions the mill samples to remove coal dust and contaminants
  • Adjustable sample and purge times
  • Sample line back-purge facility
  • Gas level display for all sample points
  • 3 adjustable levels of alarm
  • Can be fitted with up to 24 programmable relays
  • Dual sensor option
  • RS-485 Modbus communications
  • Can be tailored to suit any application
