A typical Pt100 RTD probe Luckily, resistance temperature detectors (RTDs) are an excellent alternative.

The data are 15-bit ratios between the reference resistor (in my case 427 Ω) and the RTD probe. As the temperature of the probe increases, its resistance increases in a nearly linear fashion.

The vendor’s ProSense line of process sensors now includes 0.25-inch RTD temperature probes. The three-wire, 100 ohm platinum RTD probes are made of durable 316 stainless steel and measure ...

What Are the Main Temperature Measurement Challenges? Challenges include: Current and voltage An RTD sensor is a passive device and does not produce an electrical output on its own. Excitation current ...

This software-controlled RTD emulator produces voltages that cover the output range of the sensor. It supports all three RTD wiring configurations and associated sense-wire configurations.
