Torque measurement systems
Sigma 2001/2D / Delta 4000/4D / Delta 5000/5D
Car industry Aeronautics Medical
Fields of Application
Integrated SPC Calculations
•
CAM, CP and CPK calculation and measurement of
mean & range on torque or angle values in accordance
with ISO, NF, Q544000 and CNOMO standards.
•
Calculation of ideal tolerances
•
Data screening (date or value interval)
•
Tolerance interval selection
•
‘Population homogeneity’ test
•
Normal distribution test
•
Exporting the results
The results of the readings can be exported to the
DELTAPC software in order to:
•
store the results and perform statistical calculations
•
save and display one or several curves
•
display histograms and control charts
•
transfer the results and curves to an EXCEL or other
type database.
Two Operations Modes
Acquisition Mode
In this mode, SIGMA / DELTA allows the operator to
acquire and store torque values or torque and angle
values:
•
either automatically, after each tightening operation
•
or manually, by pressing the VAL key
In manual mode, 2 types of reading are available:
•
peak: displays and stores the maximum torque read
•
track: the values displayed follow the evolution of the
torque in a continuous process.
Examples of application in track mode
•
Hand torque measuring wrenches (AWT / DWT)
•
Reading the tension in a joint with a force meter
•
Calibration of assembly machines in ‘static mode’.
In this mode, the values are not stored.
Programming Mode
With its ergonomic design, SIGMA / DELTA can be easily
programmed by using the 5 browsing and the multifunction
alphanumerical keys of the keyboard.
The main parameters that can be programmed are:
•
selection of transducer connected to unit
•
the torque measuring unit
•
the nominal torque
•
the nominal torque or torque & angle tolerances
•
the number of readings for each operation
•
the mode used to start the reading
•
the parameters used to save the curves
•
etc.
The unit is multilingual: Français, English, Espanol,
Deutsch, Italiano, Nederlands, Svenska, Portuguese.
