DropSense

For online quality control in your production process

The innovative optical droplet sensor enables a contact-free detection of nanoliter droplets in the range between 1.5 nl to 100 nl in flight.

Features:

  • Online monitoring of dispensing processes
  • Delivers qualitative information on volume, shape and velocity of the droplet in terms of so called "finger print" signal
  • Easy adaption to different non-contact dispensing systems or droplet generators


By measuring the absorption and refraction, caused by a dispensed droplet that passes the sensors’ active area, the sensor allows for a detection of droplet presence as well as further characteristics.
