Correlation Sensors – Rev. 07 as of 20.04.2016
®
In case of using other manufacturer’s transmitters the operator is obliged to
implement a system assessment according to EN 60079-25.
The required specifications for Ex-version sensors can be taken from the
EC-type examination certificate TÜV 03 ATEX 2262 or TÜV 12 ATEX 087812
WARNING
When connecting the sensor to the transmitter the metal sensor ground plate
must not exceed 1 G
Ω grounding resistance!
In this case make sure to eliminate the risk of explosive atmospheres by us-
ing a gas warning unit prior to installation or maintenance works. Please ob-
serve to avoid building up electrostatic energy during the works!
CSM Sensor
The sensor type CSM is designed for flow velocity measurement of slight to
heavily polluted media in part filled or full pipes and channels with low levels.
The CSM sensor can be operated exclusively in connection with the accompa-
nying Electronic Box EBM. For Type CSM-V100 an additional level measure-
ment is required.
DSM Sensor
The sensor type DSM is designed to measure level of liquid media using ultra-
sound from top down in pipes featuring small dimensions. The sensor can be
operated exclusively in connection with the accompanying Electronic Box EBM.
EBM Electronic Box
The Electronic Box Type EBM is conceived to connect the sensors Type CSM
and DSM. It contains the detached electronic sensor components and is de-
signed to be connected to Type PCM Pro / 4 or OCM Pro transmitters.
POA Sensor
The sensor type POA is designed to measure flow of slight to heavy polluted
media in part filled and full sewers, pipes and other channels. Level measure-
ment is additionally possible depending on the sensor type.
OCL-L1 Sensor
The sensor type OCL-L1 is designed to measure level of liquid media using ul-
trasound from top down.
CS2 Sensor
The sensor type CS2 is designed for flow velocity measurement of slight to
heavily polluted media in part filled or full pipes and channels and featuring large
dimensions and a minimum filling level of 10 cm. Level measurement is addi-
tionally possible depending on the sensor type.
Please necessarily observe the maximum permissible limit values as specified in
chapter 4. Any cases varying from these conditions without written consent of
NIVUS GmbH are entirely left at owner’s risk.
