MB7139-500

Ultrasonic technology has been used for many years in different forms, from communication to medical and industrial applications. The high speed transmission of ultrasonic waves provides a great advantage in many applications, from monitoring the thickness of steel or other materials, to measuring distance and speed, to aquarium maintenance and medical diagnostics. The MB7139-500 ultrasonic receiver/transmitter is a powerful tool for improving the performance of these applications, and is capable of easily and accurately transmitting ultrasonic waves and detecting returned echoes.

The MB7139-500 ultrasonic receiver/transmitter consists of two main components - the transmitter and the receiver. The transmitter is a transmitter-amplifier combination that is used to emit a high-frequency ultrasonic wave with a frequency range of 35kHz - 40kHz. The receiver is a high-sensitivity directional microphone that receives the returning echo. The receiver has a bandpass filter circuitry that filters out all but the desired frequency from the incoming signal.

The main application field for the MB7139-500 is the medical and industrial testing and diagnostics. The device is capable of accurately measuring the distance and speed of moving objects in a variety of environments. Its high-sensitivity microphone also allows it to detect very small differences in sound intensity and can be used for measuring thin layers of steel or other materials. The ultrasonic waves can also be used to detect air bubbles in gases, which is useful for medical and industrial applications.

The working principle of the MB7139-500 is quite simple. It emits an ultrasonic signal at a predetermined frequency and this signal is picked up by the receiver. The receiver then filters out the unwanted frequencies and amplifies the desired signal. After the signal is amplified, it is sent to the output, which is usually in the form of a voltage output. The output can be used to control the direction and speed of the moving object, or to measure the thickness of a material.

The MB7139-500 ultrasonic receiver/transmitter is a highly versatile device that is capable of providing many applications with accurate and reliable ultrasonic measurements. From monitoring the thickness of steel or other materials, to measuring distance and speed, to aquarium maintenance and medical diagnostics, the MB7139-500 is an essential tool for improving the performance of these various applications.
