Ultrasonic Receivers, Transmitters: MB7137-320 application field and working principle
The MB7137-320 ultrasonic receiver and transmitter is designed for use in industrial applications such as range finding, object recognition, point-of-point broadcasting (POBC), and short-range data communications. It is compact, lightweight, and reliable. The product is designed primarily for mounting in protective housings and features a high tolerance to environmental conditions such as noise, vibration, water spray, and oil.First, the MB7137-320 ultrasonic receiver operates using time-of-flight (TOF) technology, which enables precise object detection, range finding, and object recognition. TOF measures the time for an ultrasonic signal to travel from a transmitting point to a receiving point and back. The time taken to travel is measured in microseconds, and is used to determine the distance between the transmitting and receiving points. The device consists of a transmit (Tx) unit and a receive (Rx) unit. The Tx unit contains a piezoelectric transducer element which generates an ultrasonic signal when an electrical signal is applied. The Rx unit contains a sensor element that detects the ultrasonic signal when it reaches the receiver.The MB7137-320 ultrasonic transmitter is designed for broadcasting a continuous ultrasonic signal that is used to detect, locate, and identify objects in a short-range data communications application. The transmitter and receiver contain several components—a transmit clock, a driver circuit, a signal processing circuit, and an antenna. The Tx clock generates a train of pulses at the center frequency of the transmitting ultrasonic signal. The driver circuit amplifies the pulses and sends them to the piezoelectric transducer element. The signal processing circuit receives the returning ultrasonic signal and amplifies and demodulates it before passing it to the antenna for broadcasting.The MB7137-320 ultrasonic receiver and transmitter are designed with a high tolerance for various environmental conditions, making it an ideal choice for use in harsh industrial settings. It is a reliable and durable device that is easy to install and maintain. The device is available in a variety of configurations, providing the flexibility to meet a range of application requirements. The MB7137-320 has been used successfully in a variety of industries, from manufacturing to medical instrumentation.In conclusion, the MB7137-320 ultrasonic receiver and transmitter are reliable and cost-effective components that offer precise sensing and transmission of ultrasonic signals for a variety of industrial applications. The device is designed to operate reliably in harsh conditions, and is a reliable choice for range finding, object recognition, POBC, and short-range data communications.
