KELLER PIEZORESISTIVE PRESSURE TRANSMITTERS SERIES 23 / 25 ABSOLUTE-, GAUGE- AND DIFFERENTIAL PRESSURE These piezoresistive transmitters have been designed for precision applications in industrial environments for pressures ranging from 0,2 to 1000 bar, liquids or gas. · Series 23 Male pressure port Accuracy 0,5%FS, optional 0,1 and 0,2%FS · Series 25 Flush diaphragm Accuracy 0,5%FS, optional 0,1 and 0,2%FS • A Complete Range Absolute, barometric, gauge (over- and underpressure) and differential for wet/wet applications. 13 nominal pressure ranges. Current or voltage output. • Flexibility A modular concept uses the selection of off-the-shelf capsules, allowing a customised production. Numerous options and variants are available, fully adapted to the customer’s requirements: Mechanical and electrical interface, ports, signal outputs, materials in media contact, oil filling, oxygen-compatibility, special features, flameproof- and intrinsically safe versions. Series 23 • 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. The type of the transmitter is defined according to the reference pressure: · PAA-23/25 · PA-23/25 · PR-23/25 · PD-23 Absolute Pressure Transmitter (Zero at 0 bar abs.)
