Product Groups
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 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.
Submersible probes for level and fill measurement. With a special design and cable and housing materials that have been chosen for compatibility with their surroundings, these probes can be used in a wide range of liquids.
A variety of data logger designs for recording the pressure and temperature profile. Depending on the system, the data is read out via a plug connection or via remote transfer.
High-quality digital manometers with easily readable displays and practical additional functions. Display units for use with KELLER transmitters or for processing standard signals from other sources.
Devices for measuring and transmitting pressure values via wireless interfaces such as LoRa, Bluetooth, 2G, 3G, 4G and RFID. Alarm notifications, switch outputs and additional extras round out the range of functions on offer.
