MSA IR400 Point IR Gas Detector

MSA IR400 Point IR Gas Detector
  • Industry-leading speed & response: T90 ≤ 3 seconds even with splash guard installed
  • No routine calibration required reducing maintenance costs
  • Industry standard 4-20 mA output provides remote alarm and fault indication
  • Multiple communication outputs provide complete status and control capability in the control room
  • Heated optics eliminate condensation
  • Dirty optics indication discriminates between true fault and cleaning requirements
  • Fast calibration times reduce amount of cal gas required which lowers maintenance time and costs

Descriptions of MSA IR400

  • Model IR400 infrared (IR) point detector is a microprocessor-based combustible gas detector that continuously monitors combustible gases in the lower explosive limit (LEL) range and provides a 4 to 20 mA analog signal proportional to the 0 to 100% LEL concentration. The detector also monitors other conditions such as supply voltage and optical path integrity.
  • The IR400 detection principle is based on measuring absorption of infrared radiation passing through a volume of gas using a dual beam, single detector method. IR detector measures the intensity of two specific wavelengths, one at an absorption wavelength and another outside of the absorption wavelength. The gas concentration is determined by a comparison of these two values.
  • Most industrial point IR gas detection applications require a splash guard to protect the
    sensing element from rain and other environmental conditions. In many cases, the addition of a splash guard slows the speed of response considerably and should be taken into consideration.
  • The IR400 gas detector responds within three seconds to gas leaks even with a splash guard installed.
  • Configurations with analog output, Modbus, and HART are available. IR400 provides a twowire
    RS-485 addressable communications link conforming to Modbus protocol that is used to
    monitor the IR400’s status and settings in order to simplify installation and maintenance. Data
    available through HART or Modbus, such as configuration device settings and stored maintenance records, can be used to perform diagnostics and take corrective action before a
    problem occurs.
  • The IR400 is calibrated at the factory and needs no routine field calibration. It requires only a
    periodic cleaning of the windows and re-zeroing to ensure dependable performance

Applications

  • Chemical plants
  • Compressor stations
  • Drilling and production platforms
  • Fuel loading facilities
  • Oil well logging
  • LNG/LPG processing and storage facilities
