Sensyflow iG, Version 1.00
42/14-39 EN
3.1 Pipe components
The pipe components and weld-on adapters guarantee the defined installation of the transducer in the
pipeline. Moreover, they allow simple installation and removal of the transducer for inspection and/or cle-
aning. By closing the pipe component with a blind flange (C 25 / PN 40 according to DIN 2527) it is pos-
sible to use the measuring section even without installed transducer.
For larger nominal widths (
≥
DN 150) or non-round pipe cross-sections the transducer is installed in the
pipeline in a defined position by means of the weld-on adapter. Depending on the respective nominal
width and the desired adaption type, the versions available as standard are displayed in
see section 10
"Type overview, technical data" on page 53
.
3.2 Transducer
The transducer is constructed as push-in sensor and contains in the compact version – apart from the
sensor unit – also the complete transducer circuitry (power supply, display, measuring circuitry) located
in the connection head.
The remote version transducer consists merely of the sensor unit and the connection housing with termi-
nal block.
Dimensions and technical data of the transducers are shown in
see section 10 "Type overview, technical
data" on page 53.
3.3 Evaluation electronics
The flame-proof encapsulated housing of the evaluation electronics contains - apart from power supply,
display (optional), and sensor control - also the entire bus interface for PROFIBUS DPV1 communication.
The electronic circuitry regulates the heating power of the sensor unit, processes flow, temperature, and
diagnostic signals and provides linearized output signals and status messages at the PROFIBUS.
You can select from the following measuring value display types:
• gas temperature and mass flow value
• mass flow value numerically and as bar graph
• integrator value and mass flow value
• gas temperature
• integrator value and time
Via the SERVICE MENU you can call up current status and diagnostic signals. Internally, the maximum
and minimum mass flow and gas temperature values are recorded together with the accumulated opera-
ting hours (which can also be displayed in the SERVICE MENU).
A multitude of configurations allow the adaption of the device to different measuring tasks. A complete
listing of all parameterization possibilities can be found in
see section 7.7 "Parameterization" on page 43
