GasEye Probe H2O

Water Vapor ANALYZER

GasEye H2O is a high performance water vapor analyzer. Suitable for safety applications and process control. 24/7 continuous operation. No sample preparation. No zero drift. No field calibration. Low cost of ownership.

Features

  • H2O ranges: 0 – 1000 ppmv / 0 – 100  %vol
  • Process temperature: 0 – 500°C
  • Process pressures: 0.7 – 2.0 barA
  • Real time sensing: response time below 0.1 second
  • High selectivity: automatic compensation for interference effect from other constituents in the gas sample
  • High sensitivity: detection limit below 10 ppm per meter
  • In-situ monitoring: direct in the process, no sample preparation
  • Maintenance free: equipped with a self-calibrating feature, no field calibration necessary
  • Robustness: IP66 enclosure, suitable for outdoor and indoor installations and harsh environments
  • Insensitive to dust and smoke in the measured process: up to 50 g/m3

8 x digital output (NAMUR)
Inputs: 4 x analog input 4 – 20 mA (process temperature and pressure) – easy user selection via DIP switch between active/passive mode
1 x RTD (PT100/PT1000) – easy user selection via DIP switch between PT100/PT1000 and 2-/3-/4-wires
8 x digital input
Local User Interface: Human Machine Interface (HMI) – LCD backlight display located on the transmitter housing lid
Ethernet port:
a) WebServer – system configuration and data acquisition via web browser,
b) Windows based program – GasEye logger for real-time data acquisition,
c) remote service and diagnostics
Optional: Modbus (TCP/IP), Modbus RTU, Profinet, Profibus
Electrical Characteristics
Power input: 24  VDC nominal (19 – 30 VDC)
Power consumption: < 20 VA
Additional build-in features
Automatic gain control (AGC): AGC ensures correct gas measurement even at high dust loads resulting in loss of optical transmission down to 0.5%. AGC operates fully automatic with no need for manual adjustment of the signal gain under any process conditions.
Self-calibration features: Internal reference gas compartment is used for closed loop control of the zero and span drift
