What are Ultrasonic Sensors?

We are Ultrasonic Sensors Suppliers, Distributors & Importers in Mumbai, India. An ultrasonic sensor is a device that detects objects or measures the distance by using high-frequency sound waves. These give off a pulse of sound waves that move through the air, and once this hits an object, it finds its way back to the sensor. The sensor determines the distance of an object based on the time it took for the return sound. The sensors have many use cases, from obstacle detection for robots to distance measurement in industrial process control systems or proximity sensing on consumer electronics. They are a budget favorite, they can be used for many conditions, and the basic one we have been looking at here is robust in design, however, results may vary depending upon other factors such as temperature or surface of the object.

Ultrasonic Sensors

Product Description:

The UA18CAD series are cylindrical M18 ultrasonic sensors for diffuse, analog, and digital output applications. These sensors provide accurate distance measurements, ideal for applications like level measurement, diameter measurement, or loop control. A family of diffuse ultrasonic sensors with a sensing range from 50-400 mm, 100-900 mm, and 200-2200 with a resolution as low as 1.0 mm. Both an analog and a digital output are enclosed in the sensor. The output is either 0-10V or 4-20 mA, and the digital output is NPN, PNP, NO, or NC, which forms a window detection. Therefore it is the best choice for distance measurement, level measurement, diameter measurement, or loop control. With Microprocessor control, digital filtering has made the sensor immune to most of Electromagnetic Interferences.
