350Ω Strain Gauge Signal Conditioning Plug-on. The VT1506A and VT1507A 8-channel Strain Completion and Excitation SCPs provide strain completion and excitation voltages for 120 ohm and 350 ohm strain bridges. Connections can be made for quarter-bridge, half-bridge, and full-bridge strain gage measurements. Two SCPs are required to make strain gage measurements. The VT1506A or VT1507A SCP provide the excitation signals and bridge connections. The other SCP, the "sense" SCO, makes the measurement connections (e.g., VT1501A, VT1502A, VT1503A, VT1508A, or VT1509A). The VT1506A or VT1507A supply the bridge excitation voltage for all bridge configurations. In quarter-bridge and half-bridge configurations, the VT1506A or VT1507A supplies the strain completion circuitry.
