Mechanical Drawing


The V-Link-200  has 4 strain gauge channels that come from the factory set to Full-bridge.  When ordering these units, you must specify the bridge completion for each channel.  Half and quarter bridge completions are available and channels can be mixed and matched.  These completions are accomplished in the factory as part of the final assembly, 

See the V-Link 200 user's manual http://www.microstrain.com/sites/default/files/v-link-200_user_manual_85... on how to connect strain gauges (page 44 -45), and pages 57 - 59 on how to calibrate the strain gauge to output µstrain with the V-link-200.

The LORD MicroStrain V-Link-200 supports a wide range of Wheatstone bridge and analog sensors including acceleration, vibration, strain, load cells, torque, pressure, magnetic fields, displacement, etc.

As a basic function of support for these sensors, the node measures small voltages. The nodes can actually be repurposed to measure small currents. This is useful, for example, if one wanted to add the wireless capability of the nodes to a 4 to 20 mA sensor. See pages 50-51 of the V-Link 200 user's manual http://www.microstrain.com/sites/default/files/v-link-200_user_manual_85... for more information.
