RTD measurement unit including detection mechanism for automatic selection of 3-wire or 4-wire RTD measurement mode |
摘要 |
An RTD measurement device including a mechanism for automatic selection of a 3-wire or 4-wire configuration mode of operation. The RTD measurement device may include detection circuitry to detect whether an RTD connected to the RTD measurement device via a plurality of wire connections includes a 3-wire configuration or a 4-wire configuration. The RTD measurement device may include processing circuitry to process one or more readings from the RTD. If a 3-wire configuration is detected, the detection circuitry may automatically configure the processing circuitry to operate in a 3-wire configuration mode. If a 4-wire configuration is detected, the detection circuitry may automatically configure the processing circuitry to operate in a 4-wire configuration mode.
