Ultrasonic Receivers, Transmitters - Industrial

Ultrasonic Receivers and Transmitters are essential sensing components found in various industrial applications that utilise ultrasonic technology for numerous sensing and measurement jobs. They work together to produce, transmit, receive, and interpret high-frequency sound waves beyond the range of human hearing.   

What are Ultrasonic Receivers?

Ultrasonic receivers efficiently detect ultrasonic waves. They typically use piezoelectric transducers, which transform the received mechanical vibrations (ultrasonic waves) back into electrical signals.

Available Types of Ultrasonic Receivers

• Piezoelectric Receivers: The most typical type that uses piezoelectric crystals to produce an electrical signal when subjected to pressure waves.

Ultrasonic Transmitters: A Deep Understanding

Ultrasonic transmitters generate ultrasonic waves. They often employ piezoelectric transducers, which convert electrical energy into mechanical vibrations, generating ultrasonic waves.   

Benefits for You

• Non-Contact Measurement: No need for physical contact with the object being measured.
• Unaffected by Colour or Transparency: Can sense objects regardless of their colour or transparency.   
• Operations in Harsh Environments: Can work effectively in dusty, dirty, and wet environments.

What are the Available Ultrasonic Transmitter Types?

• Piezoelectric Transmitters: Piezoelectric crystals are the most widely used type, and they vibrate at high frequencies when an electrical signal is applied.
• Electrostatic Transmitters: Electrostatic charge is used to produce ultrasonic waves.

How Do Ultrasonic Receivers, Transmitters - Industrial Work Together?

• In a common ultrasonic sensing system, the transmitter emits an ultrasonic wave.
• The wave travels through a medium (usually air, but it can also be liquids or solids).
• If the wave encounters an object, it is reflected.
• The receiver detects the reflected wave.
• The system quantifies the time it takes for the wave to travel to the object and return.
• This time is used to analyse the distance to the object.

Typical Applications of Ultrasonic Receivers, Transmitters – Industrial Across Industries

• Distance Measurement: Analysing the distance to objects for positioning, level sensing, and collision prevention.
• Level Sensing: Observing the level of liquids or solids in tanks and containers.
• Object Detection: Detecting the presence or absence of objects on production lines or in automated systems.
• Thickness Measurement: Measuring the thickness of materials without contact.
• Non-Destructive Testing (NDT): Examining materials for faults and flaws without damaging them.
