Description

The NU200E12TR-1G operates on a piezoelectric ultrasonic principle, emitting a 200kHz acoustic pulse and measuring the time-of-flight or frequency shift caused by wind (anemometry). Its integrated design combines the transmitter and receiver into a single, compact element, simplifying system integration and improving signal stability. The sensor’s high input voltage tolerance (500Vp-p) and stable static capacitance (150pF ±20%) contribute to robust performance in variable electrical environments.

Encased in a durable stainless steel body and sealed to IP68 standards, this sensor is engineered for long-term, maintenance-free operation in demanding outdoor and industrial settings. Its wide storage and operating temperature range ensures reliability from -40°C to +85°C, making it suitable for integration into permanent weather monitoring stations, smart agriculture systems, and industrial airflow control panels.

Frequently Asked Questions

What is the operating principle of this ultrasonic wind speed sensor?

The sensor operates on a piezoelectric ultrasonic principle. It emits a high-frequency 200kHz acoustic pulse. The wind speed is typically derived by measuring the time-of-flight difference or frequency shift (Doppler effect) of the signal between the integrated transmitter and receiver, which is altered by the moving air mass.

What are the electrical driving requirements for the NU200E12TR-1G?

The sensor can handle a maximum input voltage of 500V peak-to-peak. It has a nominal static capacitance of 150pF (±20%) and a minimum parallel resistance of 600Ω (±30%). These parameters define the electrical load for the driving circuit, which typically requires a matching network or a specialized ultrasonic driver IC to excite the piezoelectric element effectively.

Is this sensor suitable for permanent outdoor installation?

Yes, its construction is ideal for permanent outdoor use. The housing is made of corrosion-resistant stainless steel and is sealed to an IP68 rating, making it completely dust-tight and waterproof even during prolonged immersion. The wide operating temperature range of -40°C to +85°C ensures reliable performance in extreme weather conditions.

How do I interpret the 'Asmith Angle' specification of 30° ±2°?

The Asmith Angle, specified at 30° ±2° with a -3dB reference, defines the width of the sensor's primary acoustic beam. It indicates the angular spread within which the ultrasonic energy is concentrated. A 30° angle provides a balanced focus, offering good directional sensitivity for wind measurement while maintaining a practical sensing area, which is crucial for accurate anemometry.
