Description

The NU200E18TR-1 utilizes a piezoelectric ceramic element to generate and receive 200kHz ultrasonic waves. This high operating frequency enables excellent sensitivity to small distance changes and provides a narrow, focused beam pattern, minimizing interference from off-axis objects. The sensor’s combined transmit/receive mode simplifies driver circuit design by using a single transducer for both functions.

Housed in a durable aluminum casing, the transducer is built for long-term reliability in industrial settings. Its electrical characteristics, including a 400pF capacitance and tolerance for high input voltage pulses (500Vp-p), are optimized for compatibility with standard ultrasonic driver ICs and microcontroller-based systems, making it suitable for integration into automation, robotics, and precision measurement platforms.

Key Features

  • 200kHz ±4% Piezoelectric Transducer: High-frequency operation ensures precise acoustic measurement and excellent signal resolution.
  • Narrow 7° ±2° Beam Angle: Focused ultrasonic beam provides accurate targeting and reduces false echoes from surrounding objects.
  • Integrated Tx/Rx Element: Single piezoelectric element handles both transmission and reception, simplifying system architecture and component count.
  • Robust Aluminum Housing: Durable construction protects the sensitive ceramic element and ensures stable performance under mechanical stress.
  • Extended Temperature Range: Maintains specified performance across a wide operating temperature from -40°C to +80°C.
  • Optimized Electrical Parameters: 400pF ±20% capacitance and 500Vp-p max input voltage compatibility with common driver circuits.
  • 0.1 to 2 Meter Detection Range: Provides reliable measurement for short to medium-range applications.

Frequently Asked Questions

What is the typical driver circuit requirement for the NU200E18TR-1 sensor?

The NU200E18TR-1 requires an external driver circuit capable of generating a high-voltage pulse (up to 500Vp-p) at 200kHz to excite the piezoelectric element. For receiving, a high-impedance amplifier or dedicated ultrasonic receiver IC is needed to process the returning echo signal from the same transducer. Its 400pF capacitance should be considered when designing the matching network for optimal energy transfer and sensitivity.

How does the narrow 7° beam angle benefit distance measurement?

The narrow 7° beam angle provides highly directional sound propagation, which minimizes interference from objects outside the primary detection path. This results in more accurate and reliable distance readings by reducing false echoes from nearby surfaces or structural components, making it ideal for applications requiring precise targeting in cluttered environments.

What is the difference between operating and storage temperature?

The operating temperature range (-40°C to +80°C) defines the conditions under which the sensor will perform within its specified electrical and acoustic parameters. The storage temperature range (-40°C to +85°C) indicates the safe environmental limits for the sensor when not powered, ensuring long-term reliability and preventing damage to the piezoelectric material and housing.

Can this sensor be used for liquid level sensing?

Yes, the NU200E18TR-1 is suitable for non-contact liquid level sensing in tanks, provided the liquid surface is within its 0.1 to 2 meter range. Its high frequency and narrow beam are effective for clean interfaces. However, factors like tank geometry, foam, or turbulence must be considered, and it may require specific mounting and signal processing to account for the acoustic impedance change at the air-liquid boundary.
