General presentation
The measuring chain is composed of two indissociable elements : the sensor and the electronic
processor.
1.1. The sensor
Each sensor is matched with its own electronics. Before switching on, be sure that serial
numbers at the sensor and the electronics identification plates are corresponding.
The operation principle of the equipment makes that the provided viscosity information is
relative : in the same fluid, at the same conditions the information is the same. But for 2 rheologically
different fluids the response can be different (despite it is perfectly repeatable).
The sensor active part is protected by an stainless tube which must not be removed.
The sensor is fixed upon its mounting flange by means of the provided 4 long screws.
See the detailed leaflet, § 2.
1.2. The processor
Its functions:
-
Powers the sensor,
-
Processes the sensor’s information,
-
Displays and transmits the process information : viscosity, temperature,
sensor’s frequency, outputs and relays states….
The processor is composed of two modes :
“UTILISATION” Mode :
The “UTILISATION” Mode makes it possible to visualize in different forms viscosity and
temperature values.
-
Visualization with bargraphs, acquisition graph
-
Access to the sensor identification data
-
Access to the “ADAPTATION” Mode blocks starting from the principal menu
“ADAPTATION” Mode :
The “ADAPTATION” Mode makes it possible to adapt the displayed data, parameters, settings
and configuration of the processor according to the using conditions.
-
Display block : makes it possible to display outputs and relays states, rough data, to
choose viscosity and temperature units and to choose the viscosity correction to active.
-
Settings block : makes it possible to set current outputs, alarms, bargraphs and graph
scales, to choose and set the modalities parameters of kinematic viscosity calculation, to
proceed to the mounting offset adjustment, to activate and define viscosity filter and to
change the Pt100 status.
-
Parameters block : makes it possible to parameter viscosity corrections, to read and
modify the compensation table, to modify security codes and to set the density coefficient.
-
Configuration block : makes it possible to SOFRASER to configure the processor with the
manufacturing data (thermal drift, calibration) and to define the viscosity adjustment data.
