Details
Model Number: 253-A001 RD-1400Ex Key Specifications/Special Features: Characteristics:Integration structure of explosion-proof, measured result can be directly worked out in azardous locationsExplosion-proof grade: Ex d II CT6Performance is stable and reliable: As detecting element is coated with glass film, it has strong shock resistance, good corrosion resistance, durable, small instrument drift small, stable and reliableComputerization: The instrument with single chip microcomputer has 4-20mA isolated DC linear standardOutput signal (can be set, to be specified when order), digital display, alarm function, a communication interface and moreNormal working conditions:
  • Environment temperatures: 0~40℃
  • The relative humidity: ≤ 80%
  • Atmospheric pressure: the average local atmospheric pressure (70-106kPa)
  • Radiation of the sun: no direct irradiation
  • Air velocity: less than 0.5m/s
  • Work location: the vertical position of ±5°
  • Vibration: only allow slight vibration or negligible vibration
  • Electric source: 220V ±22 V, 50Hz +/-1Hz
  • Gas sample temperatures: 5-40℃
  • Gas sample flow: 0.015m3/h (250mL/min)
  • Grounding: special grounding (earthing resistance should be less than 5 Ohms)
  • Output signal: 4-20mA isolated DC (load resistance is ≤ 550 Ω)
  • Alarm output: the low limit alarm and the high limit alarm can be set freely in the range of instrument
  • Alarm error is not more than the basic error
  • Alarm output contact capacity is 250V AC/1A or 30V DC/1A
  • Electromagnetic interference: no strong electromagnetic interference
  • Main technical parameters
    • Explosion-proof grade: Exd II CT6
    • The measuring range, minimum scale and basic error as shown in table 1
    • Stability:
      • Zero drift: ≤basic error/24h
      • Span drift: ≤ basic error/24h
    • Repeatability error: ≤1/2 basic error
    • Communication interface: RS 485 (optional)
    • Complete set of gas analyzer: one complete set of gas analyzer consists of analyzer, preprocess device and mounting support
    • Normally we supply analyzer and preprocess device only, if buyer needs mounting support, please make special enquiry
