■ Dimension Drawing
The 90db Medical Alert Active Piezo Buzzer is a remarkable device with several notable features.
One of the key aspects of this buzzer is its high decibel output of 90db. This loud sound is crucial in medical alert systems. In emergency situations, a high-volume buzzer can effectively draw attention. For example, in a hospital or home care setting, when a patient experiences a sudden health issue and activates the medical alert system, the 90db sound of the buzzer can quickly alert caregivers or family members even from a distance.
The piezo technology used in this buzzer is another important feature. Piezoelectric materials are known for their ability to convert electrical energy into mechanical energy and vice versa. This enables the buzzer to function efficiently. The piezo buzzer is highly reliable and has a long lifespan, which is essential for continuous use in medical applications where it needs to be ready for action at any time.
Active operation is also a characteristic of this buzzer. It means that it can be easily triggered when needed. In a medical alert system, this could be connected to a sensor or a button that a patient can press in case of distress. Once activated, the buzzer immediately starts emitting the 90db sound, providing a clear and urgent signal.
Moreover, this buzzer is designed to be compact and easy to integrate into various medical devices or alert systems. Its small size allows for flexibility in installation. It can be incorporated into wearable medical devices, bedside monitors, or other healthcare-related equipment without taking up too much space.
In conclusion, the 90db Medical Alert Active Piezo Buzzer combines a high-volume output, piezo technology, active operation, and compact design. These features make it an ideal choice for medical alert applications, ensuring that in times of emergency, the necessary attention can be quickly drawn to the patient in need.
Why Choose Our Piezo Buzzer
Piezo buzzers has been more and more popularily used as there is no magnetic field and no coil inside. Typically, piezo buzzers consume less current (less than 30mA), have a broader frequency range (2-6kHz) and wider operating voltage (3- 250V), and generate a higher SPL.
Kailitech piezo buzzers include types of taping, SMD, ultra-low frequency, high SPL, waterproof, high temperature and pressure resistant, with diameter or length and width fm 9.0mm to 100mm, height fm 1.8mm to 65mm, with resonant frequency range fm 200Hz to 15kHz and SPL range fm 65dB to 120dB. Housing material can be ABS, PBT, PPO, LCP, etc.
