GENERAL
TR-IR-CO
are transmitters for measuring concentration of
2
carbon dioxide. The sensors use Non Dispersive Infrared
technology (NDIR) with Automatic Baseline Correction (ABC),
which gives long life and good selectivity.
The transmitters give a linear output signal (4..20mA or 0..10V)
proportional to the gas concentration.
Output signal is set by jumper [JP1] (see PCB layout)).
CONTROL
To control the detector;
- Apply CO
/air blend with a concentration of 10000ppm (air
2
flow of 0,5 l/min) until the signal is stable, ~ 1 minute.
- Confirm that the output signal is 20mA or 10V.
If gas with lower concentration is used for control, the expected
output signal must be calculated according to a graph for each
model.
Contact technical support for more information.
INSTALLATION/POSITIONING
When mounting the transmitter consider density of target gas
and air movements in the room or area. See examples in
previous page.
Connect the transmitter according to the wiring diagram.
