Ultrasonic level sensor with 4-20mA output
An ultrasonic level sensor with a 4-20mA output is a type of level measurement device that uses ultrasonic technology to measure the level of liquids or solids in a container or tank. The device sends out high-frequency sound waves, which bounce off the surface of the material being measured and return to the sensor. The time it takes for the sound waves to travel to and from the material is used to calculate the distance and hence the level of the material in the tank.
The 4-20mA output is a common type of current loop signal used in process control systems. The sensor’s output signal is proportional to the measured level and varies between 4mA and 20mA. The 4mA signal corresponds to the minimum level, while the 20mA signal corresponds to the maximum level. This signal can be transmitted over long distances without signal degradation, making it ideal for remote monitoring and control.
Ultrasonic level sensors with 4-20mA output are commonly used in a wide range of industries such as chemical, oil and gas, water treatment, and food and beverage, among others. They are known for their accuracy, reliability, and ease of use, and can be installed in a variety of tank sizes and shapes.
In summary, an ultrasonic level sensor with a 4-20mA output is a level measurement device that uses ultrasonic technology to measure the level of liquids or solids in a container or tank. The 4-20mA output signal is proportional to the level of the material being measured and can be transmitted over long distances without signal degradation. Ultrasonic level sensors with 4-20mA output are commonly used in various industries due to their accuracy, reliability, and ease of use.
