MAX31865 PT100-PT1000 RTD Platinum Resistance Temperature Detector Module
For accurate temperature measurement, the MAX31865 RTD Platinum Resistance Temperature Detector Module (PT100-PT1000) stands out. Resistance temperature detectors (RTDs) are temperature sensors featuring a resistor that alters its resistance value in response to temperature changes, similar to a thermistor. In this sensor, the resistor consists of a thin strip of platinum with a resistance of 100 ohms at 0°C, hence the name PT100.
When compared to most NTC/PTC thermistors, the PT-type RTD is considerably more stable and precise, albeit at a higher cost. PT100s have been trusted for years to measure temperature in laboratory and industrial applications, earning a reputation for superior accuracy (exceeding that of thermocouples), repeatability, and stability.
The MAX31865 is a user-friendly thermistor-to-digital output converter designed specifically for platinum resistance temperature detectors (RTDs). An external resistor adjusts the RTD sensitivity, while the high-precision ADC converts the ratio of the RTD resistor to the reference resistor into a digital output. Additionally, the MAX31865 includes overvoltage protection up to 45V and offers configurable detection for RTD and cable open or short-circuit conditions.
Specifications and Features:-
- Integration Lowers System Cost, Simplifies Design
