Reliable Non-Contact Level & Distance Measurement
Pacific Automation supplies a full range of Microsonic ultrasonic sensors for accurate, non-contact distance and level measurement in industrial automation applications. Designed and manufactured in Germany, Microsonic sensors are known for their precision, robustness, and reliability, even in challenging environments where optical or mechanical sensors struggle.
Ultrasonic sensors operate independently of colour, transparency, surface finish, or ambient light, making them a versatile solution for a wide range of detection and measurement tasks.
Selecting the Right Ultrasonic Sensor
When selecting an ultrasonic sensor, it’s important to consider the application measurement, environment requirements, and system integration needs. The following factors will help ensure reliable performance and long-term accuracy.
Key considerations include:
Measurement range
Ensure the sensor’s operating range suits both the minimum and maximum distances required, with adequate margin for reliable detection. The detection zone should be free of other objects or machine parts to minimise interfering echoes.
Target material and surface
Ultrasonic sensors perform well on most materials, regardless of colour or transparency. However, irregular shapes, angled surfaces, or highly sound-absorbent materials can reduce signal reflection and affect measurement accuracy.
Environmental conditions
Consider temperature variations, vapour, and pressure. Ultrasonic sensors perform reliably in dusty and harsh environments, and sensors with temperature compensation and suitable IP ratings improve reliability. Specialised sensors are available for pressurised applications up to 6 bar.
Mounting space and sensor size
Compact machines or tight installations may require short-range or miniature sensor designs. The ultrasonic sensor’s detection zone should be considered during mounting.
Output and communication
Select the appropriate output type such as analogue (4–20 mA, 0–10 V), digital switching, or IO-Link for diagnostics and parameterisation.
Pacific Automation can assist with sensor selection to ensure optimal performance for your specific application.
