4WFB1K
1-kohm 4-Wire Full-Bridge Module
Retired Product
(not available for purchase)
(not available for purchase)
The 4WFB1K has been replaced by the 4WFBS1K.
The 4WFB1K supplies two or three legs of a Wheatstone or full-bridge measurement for a sensor having a nominal resistance of 1000 ohm. 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
