Figure 2. A block diagram of an RTD industrial temperature sensor. An RTD translates a physical quantity (temperature) into an electrical signal and is typically used to detect temperatures between ...

An earlier Design Idea described how to linearize the output of an RTD (resistance-temperature-detector) sensor and how to calculate the resistor values using a spreadsheet (Reference 1).That idea ...

2. Nomenclature for the RTD sensor wires maintains consistency, regardless of the number of wires used. This emulator supports all three RTD configurations (Fig. 3).It uses an external current ...

Multiplex Large RTD Sensor Arrays For Lower Parts Count Sept. 18, 2000 Resistance temperature detectors (RTDs) are among the most versatile and accurate of the commonly used temperature sensors.

This work presents the design, implementation, and experimental evaluation of a novel measurement circuit for four-wire resistive sensors, such as RTD thermal sensors. The proposed circuit ...
