Figure 1 The eSENSE Duct with and without display
General
The IAQ-sensor product
eSENSE Duct
(for mounting in ventilation ducts) is designed
to measure carbon dioxide (CO
2
). Option - TR is prepared for temperature
measurements by the resistive temperature probe mounted by the user. Option -Disp
displays the measured CO
2
value in ppm (parts-per-million) on the LCD.
The units are designed for connecting to Direct Digital Control (DDC) with 0-10V or
2-10V signal inputs. The two parallel signal outputs Out(1) (0-10V) and Out(2) (2-10V
or 4-20 mA) give linear signal voltages or currents corresponding to the measuring
range.
The output Out(2)
also indicates the
status
by setting the output voltage to 1V or the
output current to 2 mA when the sensor self-diagnostics detects any error.
