Abstract
A novel interface circuit, which provides the accurate voltage output related to resistance change for three-wire resistance temperature detector has been presented. Moreover, the proposed interface circuit is able to eliminate the effect of lead wire resistances. To reduces the nonidealities of current conveyors, the proposed circuit based on operational conveyors. The validation affirms by comparing the theoretical analysis between the proposed circuit and basic configuration. The PSPICE simulations were conducted five different values of lead resistances when using with Pt100. The performance of the proposed circuit was investigated through simulation results.
