K33VC High Concentration
Carbon dioxide sensor/transmitter
PRODUCT DESCRIPTION
The K33VC is a simple, low cost, state-of-theart
non-dispersive infrared (NDIR) carbon
dioxide (CO2) transmitter designed for general
purpose application.
The K33VC measures the carbon dioxide
concentration in the ambient air up to 30
volume % and transforms the measurement
data into 0-10 V and 4-20mA output signals.
A quick in field fresh-air calibration feature is
also included for fast & easy sensor
maintenance.
FEATURES
Using patented state-of-the-art non-dispersive
infrared (NDIR) wave-guide technology and
offers reliable measurements
 measurement range: 0 – 30 vol.% CO
2
 two analogue outputs:
OUT1: 0 - 10 V (= 0 - 20 vol.% CO
2
)
OUT2: 4 – 20mA (= 0 - 20 vol.% CO
2
)
 simple maintenance tool with in-field fresh-air
calibration features
 non-frill design; cost-optimized for connection
to DDCs or other controllers
 Two different housing options:
1) IP20 wall housing
2) IP45 industrial wall housing
 Two different measurement output options;
1) - 20% default setting
2) - 30% to be specified as K33VC-30%
APPLICATIONS
K33VC is a very cost-effective CO
2
sensor for
general application where measurement of high
concentration CO
2
is required.
Typical applications include the CO
2
incubator
for virus culture and concrete aging processes.
CONNECTIONS
Screw terminals
1 G+ 24 V AC/DC (+)
2 G0 System ground (-)
3 M Signal ground, internally connected G0
4 Vo Linear output (+) 0-10 V = 0 – 20 vol.% CO
2
5 Io Linear output (+) 4-20mA = 0 – 20 vol.% CO
2
6 Cal Calibration command input (S/C to M)
K33VC
IP20 wall housing
without display
Power supply has to be connected to G+ and G0. G0 is
considered as system ground. If the analogue output is
connected to a controller the same ground reference has to be
used for the K33VC unit and for the control system
