The 4WFB1K supplies two or three legs of a "Wheatstone" or full bridge measurement for a sensor having a nominal resistance of 1000 Ohms. The wheatstone bridge circuit is used to convert small changes in resistance to an output voltage. This module typically provides completion resistors for quarter-bridge or half-bridge strain gauges.
Features
- Connects directly into datalogger input terminals; "prongs" on lower surface are secured into datalogger screw terminals
- Makes accurate measurement of 1 kOhm strain gauges simple; gauges are measured with a Full Bridge measurement instruction
