CM350 Completion Module

CM350 Completion Module

We have designed our completion modules to allow for rugged input connection of your foil strain gages with custom length, integrated instrumentation cable output. Available in both 120Ω and 350Ω configurations and standard millivolt output, these rugged re-usable completion modules significantly reduce field installation time and provide an improved signal to noise ratio.
