in-situ hydrogen cyanide analyzer
GasEye HCN is a high performance in-situ hydrogen cyanide 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
- HCN ranges: 0 – 1 ppmv / 0 – 10 ppmv / 0 – 100 ppmv / 0 – 1000 ppmv
- Process temperature: 0 – 550°C
- 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 0.01 ppmv 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
- ATEX version available

Application type
Process gas temperature: | 0ºC to 550ºC |
Process gas pressure: | 0.7 – 2 barA |
Maximum path length: | up to 25 meter |
Warm-up time: | approx. 5 minutes |
Minimum response time (T90): | 100 milliseconds |
Ambient temperature: | -30ºC to +55ºC |
Ambient pressure: | 800 – 1200 hPa |
Ambient humidity: | RH < 99%, non-condensing |
Purging gas: | instrument air or N2 |
Process purge flow rates: | 5 – 50 l/min |
Sensor purge flow rates: | 0.2 – 7 l/min |
Technical specification
Outputs: | 4 x analog output 4 – 20 mA (gas concentration, process transmission, 2 x AUX) – easy user selection via DIP switch between active/passive mode |
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 |
Power input: | 24 VDC nominal (19 – 30 VDC) |
Power consumption: | < 15VA (< 25VA if ATEX) |
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 |
