CO2 industrial sensor ZMF-100-IR with measuring range up to 50,000ppm

CO2-Sensor ZMF-100-IR

Robust CO2 sensor in an aluminium housing with the optical measuring principle NDIR, used for rapid and exact carbon dioxide concentration measurement in industrial applications

Product description

The ZMF-100-IR is a CO2 sensor, based on infrared absorption measurement for detecting the CO2 concentration in the air, using the optical measuring principle NDIR (non-dispersive infrared absorption measurement). With its robust, red aluminum housing, it is perfectly suited for industrial use. The measuring range of the sensor covers 0 to 50,000ppm, which is why the device can also be integrated into plant safety concepts. It also features internal error monitoring. The measurement signals from a downstream device can be evaluated by the integrated 0...10 V or 4...20 mA signal output. The device is operated via 24 V DC and can be mounted on the wall.

Product advantages

  • Wear-free: Excellent long-term stability (service life 5 years)
  • Extremely robust housing for industrial use
  • Attractive price-performance ratio
  • Maintenance-free, due to NDIR technology
  • 4...20 mA or 0...10 V signal output
  • Low sensitivity to external influences, such as pressure fluctuations and vibrations
  • Selectable measuring ranges
