The BCM-1 bridge completion module provides a convenient means of completing the Wheatstone Bridge circuit used for strain gage measurement. The module can be used for quarter-bridge measurements with 120 or 350 Ohm gages, or for half-bridges with gages of any resistance. In addition, a bridge balance adjustment potentiometer is provided to zero the bridge output. Screw terminals are provided for strain gage, excitation and output signal connections. Quarter-bridges with two- or three-wire hook-up can be accommodated.

Rated 5 out of 5 by from Exactly what I needed This is exactly what i needed to complete my wheatstone bridge. Works great and is super easy to use with the screw terminals.

When i want to use BCM-1 as bridge completion module for half bridge with 2 gauges of 120 ohm , i dont know the gauges is opposite or in the adjacent of each other. e.g during tensile test for measuring the average strains or elimination of bending strain

Asked by: Bijan Jahanara
In the half bridge configuration the gauges are adjacent to one another.

Hi I need to measure strain on a Blade so I am wondering if this kit is the only one I need to measure strain on a blade while it is loaded?

Asked by: Al Mollaei
The picture on the web page represents the BCM-1 Bridge Completion Module being used in a complete strain measurement system. The BCM-1 is the item in the middle with the screw terminal on the top. The digital display and the actual strain gage sensor would have to be purchased separately. You can contact use at pressure@omega.com for additional info on strain gages and displays

What display and strain gauge are shown?

Asked by: balexan369
The strain gage is one of our KFH Series Linear Axis Pre-wired Strain Gages. The display is a older unit that was designed to accept a strain gage bridge input. It has been discontinued and replaced by our Platinum Series DP8PT Digital Displays
