madIR-D01 - industrial sensors

NDIR infrared sensor in flow configuration

Microprocessor equipped IR Measuring cells

IR sensors for measurement of 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 or diffusion 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

Working modes

"Smart Zero" - automatic correction of the sensor zero using values from the previous
1 to 30 days
Permanent operation in 3 phases - zero, measure, standby
Permanent operation according to timing plan (24 hr. cycle)
Permanent operation with external zeroing

Standard configuration

ABS housing with all connections
Linear voltage output - active range (begin and end) may be user-configured within the nominal range 0....10 V.
Linear current output - active range (begin and end) may be user-configured within the nominal range 0/4....20 mA
Interface RS232C
Digital output (0/5 V) – shows the activity of the sensor (0 V-measuring / 5 V-zeroing or pause)
Digital output (0/5 V) – shows the activity of the pump (0 V-still / 5 V-running)
Digital PWM output (0/5 V) - programmable output
Zeroing of sensor: manually or externally over isolated contacts
Voltage supply 13...30 VDC or 9...24 VAC

Optional equipment

Display module
Membrane pump SP 550 EC 4
Data storage on MMC 256MB
USB connection using madur adapter

Data processing and display

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