Ultrasonic Level Transmitters
For continuous level measurement, ultrasonic level transmitters are both cost-effective and high-performing. An ultrasonic level transmitter provides reliable level measurement and deliver results consistently over time. These devices find common application in advanced processing and heavy duty industries—like chemical processing, water treatment, and the food and beverage industry—where the measurement of a level has to work even under formidable conditions. Some of these conditions might include the measurement of a level in aggressive liquids, in low-pressure and high-temperature conditions, or in hazardous environments. But no matter how intense the conditions may get, ultrasonic level transmitters can do the job in a reliable manner.
Ultrasonic level transmitters have a wide detection range and can measure distances from mere centimeters to multiple meters. They are often equipped with digital displays and are readily configurable. Yet these devices are versatile, too, and can be found integrated into many different control systems across multiple industries. They are indeed a well-suited solution for many applications. They continuously and reliably provide clear measurements of liquid or solid levels.

FAQs
How is an ultrasonic level transmitter used with an ultrasonic level sensor to deliver a non-contact measurement of a liquid surface in aggressive media?
Ultrasonic level transmitters, paired with ultrasonic level sensors, deliver a non-contact measurement by emitting sound waves toward the liquid surface, which reflect back to the sensor; the time delay is used to calculate the level, making it ideal for aggressive media where direct contact is undesirable.
Is an ultrasonic sensor a cost effective solution for object detection?
Yes, ultrasonic sensors are a cost-effective solution for object detection due to their reliability, accuracy, and ability to function in various environmental conditions without requiring direct contact.
Transmitters vs Transducers
Some of the most common types of transmitters and transducers can be found on pressure instruments. Examples of these include: drop-in well pressure devices and devices that measure the pressure in a pipe or gas chamber. Transmitters and transducers can also be found on flow and speed measurement devices.
What is the difference between transmitters and transducers?
The main difference is the way they send data to the monitoring device, like a PLC. In terms of measurement, the transmitter will reference a measuring unit by sending a milliamp signal (such as 4-20 mA). A transducer will reference a measuring unit by sending a voltage signal, typically in volts or millivolts.
Why have the two different types of transmission methods?
The method will depend on the application. If the electrical connection in the application travels a short distance, a pressure transducer is the better choice. Pressure transducers are smaller with fewer active electronic components that can be upset by electromagnetic interference. Also, the voltage signals transmitted over longer distances are subject to voltage drop and signal corruption. A transmitter is better for transmitting signals over a long distance.
