Starrett digital force gauges can be used as handheld force gauges for basic applications or as a force sensor when used with a FMM Digital Force Tester, MTL and MTH Manual Tester.

DFC Series Digital Force Controller - The DFC is a revolutionary concept for force measurement using a handheld force gauge.  The DFC may be used as a high-accuracy handheld force gauge or as a digital controller for use with the FMM Digital Force Testers.  The DFC can serve as a universal interface where you set up your tests and where you configure load limits, distance limits, break limits, crosshead travel direction, crosshead speed and more.  The DFC features a measurement accuracy of 0.1% full scale with internal data sampling at 25kHz.  Display resolution is 10,000:1.  The DFC features Bluetooth®, USB and RS-232 communications plus digital I/O. 

DFG Digital Force Controller - The DFG is our basic force gauge.  The gauge measures force at an accuracy of better than 0.2% full scale.  The DFG is ideal for basic tensile and compression testing.  Test setup and operation is fast, efficient and easy for anyone.  The DFG display shows the test direction and dynamic load during testing.  Results are displayed at the completion of testing, including "Pass- Fail" when tolerance is applied.  The gauge will display statistics when results are saved to the gauge's internal memory.  Store up to 50 test results in local memory. 

Accessory Kits - The DFC and DFG Force Gauges are supplied with a complete accessory kit.  The kit includes a hook, notch, chisel, flat, chisel and point adapter.  A 150mm extension rod is included.  Adapter materials are stainless steel.  Aluminum is used for 10N and 50N capacities.  Included with the force gauge is a carrying case, USB cable, a set of testing accessories, a Quick Reference Guide and NIST-traceable Certificate of Calibration.

Test Methods

  • Limit Testing - Use load, distance or a break condition and report results at the limit including maximum load and distance at maximum load.
  • Load Average Testing - The load average test measures the load from the start and end of a test sequence.
  • Time Average Testing - Set a time duration for a test. When load is measured at the start of the test, the test concludes at the end of the time duration. Average load is measured.
  • Cyclic Count Testing - Define the number of cycles, up to 99,999 to be completed.
  • Cyclic Duration Testing - Define the duration of cycles, up to 27 hours to be completed.
  • Constant Hold Testing - Hold at a distance or load for creep and relaxation results. The maximum duration is 27 hours.
  • Contact Closure/Switch Testing - Uses the DFC force gauge to signal when an electronic switch is opened or closed as load is applied or removed.
