Description

Type of gas analyzer – fixed
Principle of measurement – optical absorbing
Material of enclosure - aluminium / stainless steel

Designed for continuous, automatic measurement of pre-explosive concentrations of methane (СН4), hydrocarbons including vapors of oil and oil products, associated petroleum gas, alcohols and also volume fraction of carbon dioxide  (СО2).

Application:

  • monitoring of air of working areas of premises and open spaces of explosive and fire-hazardous chemical, petrochemical and oil-refining productions
  • operation as a part of atmosphere monitoring system of hazardous industrial objects

 

Distinctive features:

  • a unique feature of gas analyzers ДАК is possibility to select by consumer in the menu of the device of any substance from the list without readings adjustment on TGM or verification (calibration component methane or propane is set by the manufacturer)
  • possibility of simultaneous monitoring of pre-explosive concentrations of several gases, for example, if it is required simultaneous monitoring of methane and toluene content you need to select toluene as measured component (see operation manual p. “Selection of measured component”)
  • wide temperature range from -60 to +90 С°
  • application in the conditions of the Extreme North
  • availability of analog, relay and digital, HART outputs
  • monitoring of vapors of oil products (petrol, kerosene, diesel fuel etc.)
  • constant diagnostics of sensor, monitoring of optics contamination
  • heating of measuring element, using of protective filter from dust and moisture
  • installation of sensors of own production into gas analyzers
  • availability of certificate of Russian Maritime Registry of Shipping allows to use sensor on offshore platforms, oil transportation tankers
  •  Secondary power supply and alarm units БПС-21М3 are used for supply of gas analyzers ДАК
  • Gas analyzers ДАК are supplied with the set of cable gland (for armored cable, metal hose, tubing) on special order.
