IoT Companies

Your Swiss Pressure Sensing Specialist


KELLER AG für Druckmesstechnik is Europe’s leading manufacturer of high level isolated pressure sensors ranging from 5 mbar to 2000 bar.

KELLER is well-known for its pressure transmitters, digital manometers and level probes – but it also has a strong reputation for customized solutions.

The internet of things cannot work without a vast amount of data provided by various sensors. Over the last decades KELLER realized many "smart" projects already. The direct integration of wireless solutions like Bluetooth or LoRa into our transmitters, loggers and manometers was the next logical step.

KELLER is collaborating with different IoT-service-providers to ensure smooth connection with clouds or other networks. For customers with a focus on pressure- or level-measurement and for testing we set up the KLELLER KOLIBRI Cloud which is completely free to use.
