Transducers
Piezoelectric transducers typically transmit and receive waves used for sensing. It converts energy from one form to another. The piezo transducer can convert electric charges into energy, for instance ultrasonic waves. A piezo transducer typically operate at resonant frequency with various construction options, beam patterns and power levels.

The UZ250 is a piezoelectric ultrasonic pick-up designed for pulse radiation in the frequency band of 250 kHz.
Description
The pick-up consists of a piezoelectric element connected to a small printed board with internal electronics. EMC (including EDS protection) is achieved by shielding. The main part of the sensor is an ultrasonic transducer. The ultrasonic transducer consists of a dumped piezoelectric element and tuned resonance plate. The piezoelectric element is connected to an electronic circuit that consists of a matching circuit, transmitter, and preamplifier. This amplifier transforms small reflected signal from high impedance piezo to low impedance modulated output voltage.
Features
- Suitable for distance meters and flow meters in gas
- High sensitivity
- Low driving voltage
- Internally amplified
- ¼ MHz operating frequency
- Simple assembly on printed board
- Shielding and EDS protection
- Short blind distance
