The Keller 33 X Ed / 35 X Ed Pressure Transmitter are piezoresistive pressure transmitters with pressure proof
housing and are approved for use in explosion risk areas of group II. They provide stable and accurate measurements
of absolute and gauge pressures of liquid and gaseous media in the pressure range between 0.1 and 300 bar.
The modular structure of this product range allows highly flexible applications and solutions that are tailored to
users‘ requirements. Numerous versions are available, for example with different pressure connections, materials and
filling oils, or versions for use with oxygen and with special performance characteristics.
This series features microcontroller-based electronic evaluation to ensure maximum accuracy. Each transmitter is gauged
across the entire pressure and temperature range. This provides the basis for calculating a mathematical model that
corrects all reproducible errors. The pressure value can be read via the interface and at the same time it is also
available in analog form as a 4-20 mA or 0 to 10 V version.
