Ultrasonic Pulser Receiver APR-20
The Microprocessor Based Ultrasonic Pulser Receiver Model APR-20 is a compact, high-performance instrument designed for precise flaw detection, material characterization, and laboratory research. Equipped with a powerful pulser and low-noise broadband receiver, it delivers exceptional signal clarity and repeatability for a wide range of ultrasonic transducers.
APR-20 is compatible with other Ultrasonic Instruments and allows great flexibility when configuring systems for high frequency application or for attenuative materials.
The front panel keypad allows the operator to choose parameters such as Gain, Damping, Mode, Energy etc precisely which are shown on the TFT display. BNC connectors are provided at the back for output and input connections.
Salient Features:
- High voltage broadband pulser for superior signal penetration
- Low-noise, wide dynamic range receiver for accurate signal capture
- Adjustable gain, damping, and pulse repetition controls
- Compatible with longitudinal and shear wave transducers
- Ideal for NDT, academic, and R&D applications discontinuities
