PT100 sensor for RTD Data Acquisition Card for Raspberry PiResistance temperature detectors (RTDs) are temperature sensors containing a resistor that changes resistance value as its temperature changes. PT100 thermocouple has a platinum sensor and a resistance of 100 ohms at 0°C. The sensor has a wide operating range (from -50°C to 450°C) low drift and with a maximum error of 0.5°C is suitable for precision applications. Since the platinum detecting sensor is suitable to contamination from various elements, the sensor in encapsulated in a thermally conductive metallic shield.
The PT100 is the perfect add-on to the RTD Data Acquisition 8-Layer Stackable Card
for Raspberry Pi. Each RTD card can read temperatures from 8 different PT100 sensors. Since the card is stackable to 8 layers, one Raspberry Pi can acquire data from 64 temperature sensors.
The PT100 sensor comes with three 2 meter, braided wires. Since the RTD card is compensating the wire resistance, the wires can be extended to very long ranges without any loss of accuracy.
