madIR - OEM sensors

Microprocessor equipped IR Measuring cells

NDIR infrared sensor in flow configuration

IR sensors for measurement of (CO) carbon monoxide, carbon dioxide (CO₂) and methane (CH₄) in one channel configuration. Available for many measuring ranges from 5 % to 100 % for a variety of industrial applications.

Properties

Flow measurement
Using microprocessor technology, all on one board
High resolution precision measuring technology
Short reaction time (T90 < 45 sec.)
Permanent automatic sensor check. Need for calibration shown by LED.
Temperature compensated

Data processing and display

Measured gas concentration in [ppm] or [%]
- Measured value can be read digitally over the RS232C
- Measured value is given as an analog output over the screw connections: 0/4-20 mA and 0-10 V
PC program for changing the sensor settings and for data-logging
