Focusens NTC 10k Temperature Sensor for Pipe - Easy Installation

This sensor is a passive NTC thermistor, providing a variable resistance output. To read the temperature, you must integrate it into a measurement circuit, typically a simple voltage divider. The resistance change can be measured by a microcontroller's analog input pin or a dedicated signal conditioner to convert it to a voltage proportional to temperature.

The sensor is designed for straightforward surface mounting onto pipes. Ensure the pipe surface is clean for optimal thermal contact. The unit can be secured using standard pipe clamp brackets, thermal adhesive, or mounting tape, depending on the required permanence and thermal transfer efficiency for your application.

Yes, it is compatible with development platforms like Arduino and Raspberry Pi. You will need to create a voltage divider circuit using a fixed resistor (e.g., 10kΩ) in series with the NTC sensor. Connect the midpoint to an analog input pin (ADC) on your microcontroller. Code libraries are available to convert the measured voltage into temperature using the Steinhart-Hart equation or a lookup table for the NTC's beta value.

The thermal time constant of approximately 6 seconds indicates how quickly the sensor responds to a step change in temperature. A lower time constant means faster response, which is crucial for applications requiring real-time temperature control or detection of rapid thermal transients in fluid systems.

While not strictly limited, long wire runs can introduce measurement errors due to cable resistance and noise pickup. For best accuracy, use shielded twisted-pair cable for the sensor leads and keep runs as short as practical. For industrial installations over long distances, consider using a local signal conditioner or transmitter near the sensor.
