Enhance your Temperature Sensing with the MAX31865 PT100/PT1000 RTD Digital Converter Temperature Sensor Amplifier

Discover unparalleled precision in temperature sensing through our MAX31865 PT100/PT1000 RTD Digital Converter Temperature Sensor Amplifier. This cutting-edge device utilizes Platinum Resistance Temperature Detectors (RTDs) to deliver unrivaled accuracy in temperature measurement. RTDs, containing a platinum-based resistor that modifies its resistance in response to temperature fluctuations, outshine traditional thermistors.

Unlike conventional thermistors, the PT100 RTD within this sensor incorporates a slender strip of Platinum, boasting a 100-ohm resistance at 0°C, earning its distinctive name. Renowned for stability and precision, PT100 RTDs surpass NTC/PTC thermistors, making them the preferred choice for laboratory and industrial applications. Their exceptional accuracy, repeatability, and stability have elevated PT100 RTDs above even thermocouples.

To fully harness the precision and accuracy of your PT100 RTD, a dedicated amplifier is imperative. Particularly crucial is an amplifier capable of reading low resistance values while adeptly compensating for connecting wire resistance. Seize the opportunity today with our exceptional RTD Sensor Amplifier featuring the MAX31865 breakout, universally compatible with 2, 3, or 4 wire PT100/1000 RTDs.

Although our selection includes various MAXIM thermocouple amplifiers, the MAX31865 stands out by catering to all your RTD requirements. It boasts the unique ability to compensate for 3 or 4 wire RTDs, enhancing accuracy to new heights. Seamlessly interface with any microcontroller using the SPI interface, effortlessly extracting the resistance ratio from the integrated ADC. To facilitate your journey, we’ve integrated a 430 0.1% reference resistor onto the breakout, accompanied by comprehensive example code for simplified temperature calculation based on resistance.

Designed to seamlessly integrate into your projects, our breakout ensures 5V compliance through a built-in 3.3V regulator and level shifting. This compatibility extends to Arduino and various microcontrollers, granting you the flexibility to explore limitless possibilities.

Each order encompasses a meticulously assembled RTD amplifier breakout board. Additionally, we provide two 2-pin terminal blocks for streamlined RTD sensor connectivity, along with a pin header for effortless integration with breadboards or perfboards. Please note that a PT100 RTD is required for operation, which can be conveniently procured from our store. Minimal soldering is necessary to affix the headers and terminal blocks, a straightforward task with basic soldering tools.

Elevate your temperature sensing endeavours today with the MAX31865 PT100/PT1000 RTD Digital Converter Temperature Sensor Amplifier. Experience the pinnacle of accuracy and precision in temperature measurement like never before.
