PT100 Head Type Temperature Sensor 10 inch Probe – Compoden
PT100 Head Type Temperature Sensor – 10 inch Long Probe
The PT100 head type temperature sensor features a platinum RTD element housed in a rugged connection head with a 10-inch (254 mm) stainless steel probe. It provides precise temperature measurement from -50°C to 400°C, making it suitable for industrial process control, scientific experiments, and DIY automation. The 3-wire configuration ensures accurate readings by compensating for lead resistance, and the standard terminal block simplifies wiring.

Compatibility
This sensor works with any RTD input module, such as the MAX31865 amplifier, which is widely available for Arduino, ESP32, and Raspberry Pi. It also connects directly to industrial PID controllers and PLCs. The recommended excitation current is 1 mA maximum to avoid self-heating, and supply voltage depends on the amplifier used (typically 3.3V or 5V). Pair with a MAX31865 for digital output via SPI, or with an analog front-end for direct ADC reading.
Wiring Notes
Inside the connection head, three terminals are provided: two carry the PT100 element signal, and the third is a compensation lead for 3-wire measurement. Connect all three to your RTD amplifier or instrument, matching the wiring diagram carefully. Keep lead wire runs as short as possible, and use shielded cable in electrically noisy environments. Always tighten terminal screws securely to prevent intermittent readings.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino?
Yes, when used with a MAX31865 RTD amplifier module, this sensor connects easily to Arduino, ESP32, or Raspberry Pi through the SPI or I2C interface of the amplifier.
Can I use this to measure liquid temperature?
The probe is sealed and can be immersed in non-corrosive liquids. For aggressive chemicals or pressurized systems, install it inside a thermowell for protection.
What is the difference between a thermocouple and a PT100 RTD?
PT100 RTDs offer higher accuracy and long-term stability compared to most thermocouples. This sensor uses a platinum resistance element, whereas thermocouples generate a voltage, so wiring and interfacing differ.
