Servo Module

  • Dual 5kHz control loops per module
  • 0.01 to 100Hz cycle frequency to meet all your testing needs
  • Digital on-the-fly adjustment of all PID parameters
  • Multichannel selectable feedback from any sensor (or sum of or difference between sensors) on any acquisition card
  • Hardware function generator
  • Bumpless transfer between control methods
  • 16 bit Analogue Voltage (±10V and (0 to 10)V) and Current (±40mA, (0 to 20)mA, and (4 to 20)mA) control output for servo valve or other control device

DIMENSION Key Features

 

Profile Builder

Choose from standard predefined test routines for simple, reliable configuration and testing to Local, National and International standards or, design and store custom routines with multiple stages where each of the following can be varied:

  • Pick your analysis method for each transducer from the Analysis Dropbox (e.g. Sinusoidal Regression, Peak-Offset, Mean…)
  • Choose your calculation from the Calculation Dropbox (e.g. EN 12697-24- 2012, AASHTO TP62…) to act upon the analysed data
  • Setup your waveform: Static, Ramp, Square, Triangle, Sawtooth, and Arbitrary (1024 datapoints can be loaded directly from a Microsoft™ excel or text file).
  • Choose your control transducer for the hardware PID loop
  • Choose your control method from the Control Dropbox – allows for cascade control via any Analysis or Calculation parameter and many other advanced control methods
  • Setup limits for each transducer to ensure their safety in the event of specimen failure
  • Select your stage end criteria: Cycles/Time, Transducer Value, Failure (set your percentage and threshold)
  • Setup what data is logged to file and when. Raw and Summary data are independently logged to file on a time-based, cyclic and/or transducer value interval All data is logged to a text file which can be opened directly in Microsoft Excel for further analysis
  • Setup hardware triggering, again on a time-based, cyclic and/or transducer value interval
  • Create dialogue boxes to instruct your technicians at critical points during the test
  • Setup manual control stages for initial setup and user interactive parts of the test
  • Choose your report template from the Report Dropbox to generate a pdf report at the end of the test

Hardware Database

  • Store, access, and edit all your hardware information:
  • Transducer Calibration Data with TEDs (Transducer Electronic DataSheet) interface to read all setup information directly from the embedded TEDs chips on all connected transducers.
  • Servo Card Setup allows configuration to match your specific hardware.
  • Digital Card Setup to configure hardware triggers, control valves, switch inputs etc.
  • Acquisition Card Setup for input channel configuration

Main Test Screen

 

With all the information and control you need during the testing phase:

  • Stage indicator shows the configuration of all test stages and indicates the current stage
  • Transducer indicator shows the current average value of each active transducer
  • Analysis indicator shows the current value of each value given by all transducer analysis routines
  • Calculation indicator shows the current value of each calculation output
  • Waveform graph shows the current cycle for any attached transducer(s) in realtime
  • Summary chart shows the entire history of Analysis and Calculation outputs through the current test stage again in real time
  • X-Y Waveform graph allows transducer waveforms to be plotted against another transducer for a real-time view of hysteresis
  • X-Y Summary chart gives the you the flexibility to see the relationship between one parameter and another during the test e.g. force-extension, temperature extension,temperature-force
  • Limits monitor gives an indication of all transducers and their value relative to the limits of their range
  • Skip to next stage and stop test buttons allow for manual intervention during the test
