4WFB120

120 Ohm 4-Wire Full Bridge Module

Retired Product
(not available for purchase)

The 4WFB120 supplies two or three legs of a "Wheatstone" or full bridge measurement for a sensor having a nominal resistance of 120 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 120 Ohm strain gauges simple; gauges are measured with a Full Bridge measurement instruction
