Abstract: The output voltage of a Wheatstone bridge type electrical circuit compris four main resistances (J.sub.1 to J.sub.4) having substantially the same ohmic value, R, and substantially the same temperature coefficient of resistance, .alpha., is made independent of temperature differences existing between the branches of the bridge by addition, in each of the branches, of a compensation element (r.sub.1 to r.sub.4) in series with the main resistance, each compensation element being physically located very close to a main resistance situated in one of the adjacent branches of the bridge so as to have the same temperature as that main resistance. The compensation elements have the same ohmic value r and the same temperature coefficient of resistance .beta., with R.alpha.=r.beta., r being less than R and, preferably, r/R.ltoreq.1/2, so as to limit the loss of sensitivity of the Wheatstone bridge to variations in the resistances of the bridge.
