Since many general-purpose instruments do not provide internal bridge completion capability, the MRF-Series of BCMs effectively implements a full Wheatstone bridge for accurate and stable measurements when testing specimens structured as a -bridge (single gage) or -bridge (dual gages).

Key Points: 
  • Since many general-purpose instruments do not provide internal bridge completion capability, the MRF-Series of BCMs effectively implements a full Wheatstone bridge for accurate and stable measurements when testing specimens structured as a -bridge (single gage) or -bridge (dual gages).
  • The accuracy of the strain measurement depends on the quality of the strain gage used, but also on the bridge completion circuit attached to it.
  • The MRF-Series modules are offered in several configurations that will allow for bridge completion for 120, 350, 1000 and now 5000 ohm quarter-bridges along with half bridge completion as well.
  • These versatile modules also enables a user to make -bridge and -bridge inputs to instrumentation that may not have internal Wheatstone bridge completion built-in.
