Frequently Asked Questions

What is the output signal type of the NU125E25TR-2 sensor?

The NU125E25TR-2 provides an analog voltage output. The output voltage varies linearly with the measured distance or liquid level, allowing for continuous, high-resolution data acquisition by microcontrollers (like Arduino), PLC analog input modules, or data loggers.

What is the typical operating voltage for this 125kHz ultrasonic sensor?

While the exact voltage range is model-specific, piezoelectric ultrasonic transducers like the NU125E25TR-2 typically require a low-voltage AC excitation signal (often around 5-20Vpp) for transmission. The received analog signal output is generally compatible with standard 3.3V or 5V logic microcontroller ADC inputs. Always consult the specific driver circuit requirements.

Is this sensor suitable for outdoor or harsh environment use?

The ceramic construction offers good durability against moisture and many chemicals. However, for prolonged outdoor or harsh industrial use (extreme temperatures, direct water jets), it is recommended to provide additional environmental protection for the sensor's electrical connections and mounting assembly to ensure long-term reliability.
