Product Overview
The QS150 is a compact low-frequency broadband transducer that integrates dual-band acoustic output (covering both low-frequency dynamics [20 Hz–2 kHz] and high-frequency piezoelectric ceramic radiation [2 kHz–8 kHz]), wide-bandwidth power amplification control, and multiple protection features. Designed for specialized applications such as sonar testing and evaluation, low-frequency mechanical noise simulation, and hydrophone calibration, the device boasts an overall bandwidth of 20 Hz–10 kHz, with operational capabilities at depths exceeding 300 meters and weighing only 30 kg in air. Its compact design facilitates deployment across various platforms and enables standalone operation, meeting the high-precision requirements of underwater acoustic experiments and equipment calibration.
Description of Characteristics
• Dual-band Composite Acoustic Performance
Comprising low-frequency components (20Hz–2kHz, driven by dynamic coils) and high-frequency components (2kHz–8kHz, radiated by piezoelectric ceramics), with an overall bandwidth spanning 20Hz–10kHz. This design balances low-frequency penetration capability with high-frequency resolution, making it suitable for complex acoustic applications such as sonar testing and offshore security underwater detection.
Sound source level>150 dB (reference: 1 μPa @ 1 m), ensuring clear detection and effective coverage of acoustic waves in the far field, meeting the strong signal requirements for sonar performance evaluation.
• Broadband Amplifier with Dual Operating Modes
featuring a low-frequency bandwidth of 0–10 kHz and supporting both constant current and constant voltage operation modes, enabling flexible adaptation to various loads and testing conditions.
• Multi-level Monitoring and Protection Mechanism
The power amplifier integrates voltage/current monitoring outputs, featuring overcurrent, overtemperature, and overvoltage protection functions to ensure long-term stable operation of the equipment.
• Versatile Across Multiple Scenarios
Supports professional applications including sonar testing and evaluation, low-frequency mechanical noise simulation, and hydrophone calibration.
