Baumer is now responding to this challenge with the new

Series 09 ultrasonic sensors. They are capable of measuring

into wells with as little as 3.3 mm opening diameter, providing

a 0.1 mm resolution. This performance converted to a type

384 microplate results in a resolution of 1.09 microliters.

Thus, the loss of liquid can be kept within very tight limits.

Additionally, the measurement allows the detection of flaws at an early stage of the analyzing process, which

keeps the general process quality at a high level. Efficiency concerning scanning speed is a further highlight of the

Series 09 sensors. Thanks to a housing width of less than 9 mm, eight sensors arranged in-line are capable of

scanning a type 96 microwell plate in one single cycle. The short response of as little as one millisecond allows

fast scanning rates, which in turn lead to minimal process times. The benefit are a maximum of process quality at

a minimum loss of time.

The range of applications for the new ultrasonic sensors is far larger than the described liquid level measurement

in lab automation systems. In any application where small objects need to be detected, the Series 09 sensors

demonstrate their strengths. For instance, medical capsules and tablets, which have been placed in blister

packaging, can be reliably detected. Non-contact ultrasonic sensors are able to detect transparent and

multicolored objects precisely, which ensures a long-term high quality in packaging processes.
