Product catalog summary

General Overview: The document provides technical specifications for the smartGAS FLOW EVO infrared gas sensor, specifically designed for detecting methane (CH4) and bromomethane (CH3Br). The sensor is pre-calibrated, compact, and features a low drift design with LED status indication.

Specifications:

Measurement Principle: Non-Dispersive Infra-Red (NDIR), dual wavelength.
Measurement Range: 0 to 15 Vol.-% for CH4.
Gas Supply: By flow at nearly atmospheric pressure with a flow rate of 0.1 to 1.0 l/min.
Mounting Dimensions: 116 mm x 30 mm x 50 mm.
Warm-up Time: Less than 2 minutes for start-up, less than 30 minutes for full specification.

Performance:

Digital Resolution: 0.001 Vol.-%.
Response Time: t90 ≤ 10.8 s, ton ≤ 16.5 s at 0.7 l/min.
Detection Limit: ≤ 0.015 Vol.-%.
Repeatability: ≤ ± 0.05 Vol.-%.
Linearity Error: ≤ ± 0.1 Vol.-%.
Long Term Stability: Zero ≤ ± 0.1 Vol.-% over 1000 hours, Span ≤ ± 0.9 Vol.-% over 1000 hours.

Environmental and Electrical Specifications:

Operating Temperature: 0 to +50 °C.
Storage Temperature: -20 to +60 °C.
Air Pressure: 800 to 1150 hPa.
Humidity: 0 to 95% relative humidity (non-condensing).
Supply Voltage: 3.3 to 6.0 VDC.
Power Consumption: Average < 800 mW.
Output Signal: Modbus ASCII/RTU via UART.

Recommendations:

Recalibration is recommended at first initiation and periodically depending on application and ambient conditions.
Consult smartGAS for parts with different temperature and measurement ranges.
