Ultrasonic sensor

Our ultrasonic sensors are self-contained solid-state devices designed for non-contact sensing of solid and liquid objects. For many applications, such as monitoring the level of water in a tank, ultrasonic technology lets a single device to do a job that would otherwise require multiple sensors. Our sensors are available in several sensing ranges and styles with either an analog or discrete output depending on the model. Proximity-Style Ultrasonic Sensors Our Bulletin 873C Proximity-style Ultrasonic Sensors can detect solid and liquid targets from a distance of up to 1 m (3.3 ft). We offer two versions of this sensor: a background suppression unit with analog voltage output or a standard diffuse mode with a digital output. Product Details Analog or Discrete Output Ultrasonic Sensors Our Bulletin 873P Analog or Discrete Output Ultrasonic Sensors are IO-Link enabled, and are ideal for applications that can be challenging for other sensing technologies, such as in the detection of clear, shiny or non-reflective objects. These sensors offer a wider range of operating voltages and simplified push-button setup. Product Details General Purpose Ultrasonic Sensors Our Bulletin 873M General Purpose Ultrasonic Sensors are designed to detect solid or liquid targets by using sound waves. These compact sensors provide enhanced flexibility for areas with limited space and are excellent for standard packaging and assembly applications. They are ideal for sensing targets that are challeng...

Ultrasonic sensors are in available for the past many decades and these devices continue to hold huge space in the sensing market because of their specifications, affordability, and flexibility. As the automation industry has been progressing, the employment of ultrasonic sensors in multiple domains such as drones, EV vehicles is emerging. In the year 1914, Fessenden developed the first modern transducer employed in sonar where it can be able to find the items in water but not the direction of items. And then in the year, 1915 Langevin introduced the contemporary model of ultrasonic which resolved the problem of Fessenden. ultrasonic sensor definition, how it works, it’s specifications, its integration with Arduino, and its advantages are explained clearly in this article. What is Ultrasonic Sensor? Ultrasonic sensors are electronic devices that calculate the target’s distance by emission of ultrasonic sound waves and convert those waves into electrical signals. The speed of emitted ultrasonic waves traveling speed is faster than the audible sound. There are mainly two essential elements which are the transmitter and receiver. Using the piezoelectric crystals, the transmitter generates sound, and from there it travels to the target and gets back to the receiver component. To know the distance between the target and the sensor, the sensor calculates the amount of time required for sound emission to travel from transmitter to receiver. The calculation is done as follows: Ult...

Dec 24, 2021 By Team YoungWonks * What is an ultrasonic sensor? In a previous blog post ( What is an ultrasonic sensor? An ultrasonic sensor is an electronic device that can measure the distance of a target object by sending out ultrasonic sound waves, and converting the reflected sound into an electrical signal. Basically, such a sensor uses a transducer to send and get ultrasonic pulses that in turn send back information about an object’s proximity. It is important to note that these ultrasonic waves travel faster than audible sound; i.e. these sensors send out sound waves at frequencies above the range of human hearing. Ultrasonic sensors have two key components: one is the transmitter that emits the sound using piezoelectric crystals and the other is the receiver that receives the sound after it has traveled to and from the target. How does an ultrasonic sensor work? As mentioned earlier, an ultrasonic sensor sends out a high-frequency sound wave to begin with; here the transducer acts as a microphone to send the ultrasonic pulse / sound and receive the echo. The sensor then deduces the distance to the object by measuring time lapses between the sending and receiving of the ultrasonic pulse. In other words, it calculates the distance by measuring the time it takes between the emission of the sound by the transmitter to its contact with the receiver. The formula for this calculation is D = ½ T x C (where D is the distance, T is the time, and C is the speed of sound ~ 34...

Standard and custom sensors for various process control applications Our ultrasonic sensors measure liquid level despite variations in transparency, viscosity, color, or dielectric. These solutions include air bubble detection for medical pumps; point and continuous level sensors for the semiconductor and high purity markets; and point level sensors for a variety of process control applications. We offer high accuracy, high frequency, short range continuous measurement ultrasonic sensors through air for process control. We manufacture standard and custom products that provide a system without moving parts, adjustments, or maintenance. • Compatibility with a range of liquids and gases for sensors in direct contact with the media • No moving parts with outputs available in switch configurations or continuous measurements, as well as AC and DC inputs • Continuous ultrasonic liquid level sensor design for ultra-high purity applications (SL-900 Series) • Air-bubble detectors for critical applications such as infusion pumps, hemodialysis and blood flow monitoring where interruption in performance can be life-threatening (AD-101) Advancing Medical Technology TE worked with medical device designers to create a sensor that monitors the ideal temperature and humidity levels within a newborn’s incubator. Precisely maintaining this critical environment is just one of the many ways we’re advancing medical and healthcare technology.
