Transducers USA, an industry leading supplier of audible signal devices, has announced the introduction of its new custom Ultrasonic Sensors. These new devices include both a proximity sensor and an ultrasonic speaker, providing both detection and an audible alert notifying the occurrence of a specified condition. The non-contact sensing technology measures distance to an object by emitting sound waves and receiving the echo signal using a single ultrasonic element, unlike optical sensors which require both a transmitter and receiver. The ultrasonic speaker emits sound waves at high frequencies (25,000 Hz to 40,000 Hz), which are inaudible.
Transducer USA’s Ultrasonic Sensors can detect a wide range of materials: hard, soft, any color, flat or curved. They can also reflect off transparent objects, such as glass or a liquid surface, and are stable for targets such as mesh trays or springs. Detection is not affected by dust or dirt; rugged Ultrasonic Sensors are largely immune to environmental conditions indoors or out. The use of solid state technology eliminates the use of mechanical parts to break, extending the operating life of the device, and prevents dangerous sparking. Unlike traditional proximity sensors, Ultrasonic Sensors operate over longer distances and can be programmed to establish a user-specified distance range.
While Ultrasonic Sensors have a variety of applications, their primary functions include detection and level measurement. They are ideally suited for material handling, food and beverage, fill level measurement or detection at gates and doorways, as well as other diverse applications.
Ultrasonic Sensors can measure dynamically changing diameters, distances, heights, depths and count the number of units. A sample list of applications includes:
- Forklifts & Pallets – to determine if a pallet is on the fork and how far it’s inserted under the pallet
- Refuse Collection – sensors can withstand extreme temperatures, violent jolting and vibration for reliable and safe operation
- Landscaping Spray Systems – tree sprayers require the ability to measure and control the distance of the spray to the tops of trees to maintain efficient use of chemicals
- Tank & Silo Measurement – provides level measurement of liquids such as milk, chemicals or lacquer, as well as mud, sludge or bulk goods, such as sand, or gravel
- Agricultural Equipment Sprays – the boom height of sprayers must be monitored and adjusted to optimize the spray coverage and prevent the boom from impacting crops or soil
- Collision Detection – avoids serious accidents from collision with other industrial or construction equipment, such as aerial work platforms
- Vehicle Detection – as used in barrier/gate systems in parking lots and garages or car washes
- Counting – detection and counting of bottles or other products on production lines and conveyors; optimizes entry and exit of products in the workflow
- Production Downtime – detection of adverse production conditions and costly downtime, such as a web break on a printing press
- People Detection – identifies and counts humans entering the distance band
- Automation equipment – on/off switching, relay connections, PLC inputs and multi-sensor detection networks
- Robotic sensing – distances, collision avoidance, etc.
Ultrasonic Sensors from Transducers USA include the following specifications and ratings
- Solid sealed aluminum housing or commercial plastic housing
