The universal application solver
The sensors of the UM30 product family impress with high flexibility. Various sensing ranges of up to 8,000 mm as well as countless configuration options leave no applications unsolved. The high measurement accuracy provided by internal temperature compensation, along with color-independent object detection, immunity to contamination, and a wide operating temperature range up to 70 °C all ensure reliable operation, even under the most challenging conditions.

ADVANTAGES
Virtually unlimited use – regardless of color, gloss, and transparency
SICK ultrasonic sensors perform measurement and detection tasks in a wide variety of application areas on colored, shiny, or transparent surfaces, which are particularly challenging for optical sensors. Even adverse ambient conditions such as dust, dirt, or fog hardly affect the measurement result. The broad detection range also allows for a large field to be monitored with just one sensor – with a measuring range of 13 mm to 8 m. No matter where they are: the ultrasonic sensors from SICK are at your side in any industry. The extensive product portfolio offers you a wide range of solutions for your application. See for yourself.

(Acoustic) time-of-flight measurement
The sensor emits an acoustic pulse that is reflected by the object being detected. The time required for the pulse to go from the sensor to the object and come back again is measured, evaluated and converted into the distance as follows.
Distance = speed of sound x total acoustic time of flight (t2) / 2


Scanning range of ultrasonic sensors
In general on ultrasonic sensors, the less sound the object being measured absorbs, the greater the possible scanning range. The operating range specifies the distance up to which measurement on common objects with sufficient operating reserves is possible. Under ideal conditions, the sensor can even be used up to its limiting range. Switch panels are used for ideal assessment of application capability. The dark blue area shown in these switch panels shows an example of the sensor's working range if a round rod is detected. The light blue area shows the maximum detection range (limiting range) which can be achieved under ideal conditions for easily detectable objects, such as the aligned plate given here. This area between the sensor and the measuring object should be kept free of other objects to prevent them from being detected accidentally. The detectability and detection range of an object depend on its reflective properties, size, and alignment. Depending on the application, the sensor may also be able to detect very small objects, e.g. metal wire.

Applications in focus
Ultrasonic sensors are true all-rounders. SICK ultrasonic sensors demonstrate their reliability and precision in virtually any application, from measuring distances or detecting solid, powdered, or liquid media. No matter the industry, no matter the application.

SICK ultrasonic sensors show their strengths in the contact-free detection of objects in all imaginable applications. These all-rounders reliably and precisely master all automation requirements on your processes.

Individually adjustable sonic beams – the optimal solution for your application and unique in the market
Adjusting the sensor sensitivity gives you direct control of the sonic beam's behavior and, therefore, the sensor's detection range. This means objects in the environment can be displayed or blanked – with infinite adjustment.
It doesn’t matter whether the sonic beam is large or small, narrow or wide, or whether the detection range is slowly increasing or the largest size possible. Tank walls, for example, can be blanked in level applications, different container sizes can be verified when inspecting empty containers, and even larger areas can be monitored with just one sensor.

The infinitely and individually adjustable detection range is the optimal solution for your application. If the ambient conditions change, the sensor can be quickly and easily adjusted to the new requirements. Thanks to the Connect+ software or the SOPAS Engineering Tool from SICK, there are practically no limits to the adjustment options.

IO-Link
As a co-founder of IO-Link, SICK offers one of the broadest IO-Link portfolios on the market. Smart Sensors with IO-Link generate and receive data and information which goes beyond conventional switching signals or measured process parameters.

SICK LifeTime Services
SICK’s services increase machine and plant productivity, enhance the safety of people all over the world, provide a solid foundation for a sustainable business operation, and protect investment goods. In addition to its usual consulting services, SICK provides direct on-site support during the conceptual design and commissioning phases as well as during operation.
The range of services not only covers aspects like maintenance and inspection, but also includes performance checks as well as upgrades and retrofits. Modular or customized service contracts extend the service life of plants and therefore increase their availability. If faults occur or limit values are exceeded, these are detected at all times by the corresponding sensors and systems.
