PRESSURE TRANSDUCERS
Encapsulated piezoresistive pressure transducers for absolute and gauge pressure measurement are KELLER's core competence and lie at the heart of all KELLER products for end users. They have proved their worth millions of times over and are a reliable base for any measuring system. Transducers can be adjusted and optimised according to your needs.

PRESSURE TRANSMITTERS
Pressure transmitters are sensors that use additional electronics to compensate for linearity deviations and temperature errors, outputting measurement results as standardised signals. Every transmitter is measured over the entire pressure and temperature profile and compared to the desired signal span.
