Flexibility
A modular concept uses the selection of off-the-shelf capsules, allowing a customised pro-
duction. Numerous options and variants are available, fully adapted to the customer鈥檚
requirements: Mechanical and electrical interface, ports, signal outputs, materials in media
contact, oil filling, oxygen-compatibility, special features, flameproof- and intrinsically safe
versions.

Reliability / Quality
These transmitters use the highly stable KELLER Series 10 capsules, proven in millions of
applications throughout the world. Each capsule is subjected to severe tests and calibration
procedures. The transmitters are manufactured and tested according to ISO 9001 / EN
29001.
