A pressure sensor (or pressure transmitter) converts the physical quantity 'pressure' into an industry-standard signal. In addition to a wide range of pressure sensors for general industrial applications, we offer special versions for refrigeration/air conditioning technology, the food industry, mobile working machines, medical gases and also the semiconductor industry. Our pressure sensor portfolio covers accuracies from 0.05 %, measuring ranges from 0.05 bar up to 15,000 bar, digital interfaces such as CANopen and IO-Link and also various international approvals, including for hazardous areas.
