MemsFrontier MTP10-B6F55 Analog Temperature Sensor Probe - B6F55 Thermistor

The MTP10-B6F55 provides an analog output based on the resistance change of its integrated B6F55 NTC thermistor. This resistance varies predictably with temperature, which can be measured directly as a voltage drop across a simple voltage divider circuit. This analog signal is compatible with standard microcontroller ADC inputs or analog data acquisition systems.

To interface with an Arduino, connect the probe in a voltage divider configuration using a fixed pull-up resistor (e.g., 100 kΩ) to a 5V or 3.3V supply. Measure the voltage at the divider's midpoint with an analog input pin. For Raspberry Pi, which lacks native analog inputs, you will need an external ADC module (like an ADS1115) to convert the probe's analog resistance signal into a digital value for the Pi's I2C or SPI interface.

The Beta (β) value of 3950 K defines the thermistor's resistance-temperature relationship, specifically between two reference points (25°C and 50°C). This constant is critical for calculating precise temperature from measured resistance using the Steinhart-Hart equation or a simplified Beta parameter formula. The ±1% tolerance on this Beta value indicates a high degree of consistency and accuracy for the sensing element.

The sensor has a specified thermal time constant of 0.032 seconds. This indicates a very fast response to changes in ambient temperature, allowing it to track rapid thermal transients effectively. This makes it suitable for applications requiring real-time temperature feedback, such as in control loops or for monitoring dynamic processes.
