Complete Range Absolute, barometric, gauge (over- underpressure) differential wet/wet applications. nominal pressure ranges. Current voltage output. Flexibility modular concept uses selection off-the-shelf capsules, allowing customised production. Numerous options variants available, fully adapted customer's requirements: Mechanical electrical interface, ports, signal outputs, materials media contact, filling, oxygen-compatibility, special features, flameproof- intrinsically safe versions. Reliability Quality These transmitters highly stable KELLER Series capsules, proven millions applications throughout world. Each capsule subjected severe tests calibration procedures. transmitters manufactured tested according 9001 29001.
