Pressure Transmitters Series 23 / 25 - 1

Piezoresistive Pressure Transmitters 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 Flush diaphragm 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. 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 type of the transmitter is defined according to the reference pressure: PAA-23/25 Absolute Pressure Transmitter (Zero at 0 bar abs.) Sealed Gauge Pressure Transmitter (Zero at 1 bar abs.) Differential Pressure Transmitter (wet / wet) Vented Gauge Pressure Transmitter (Zero at atmospheric) Series 25 with Cable Cavo ø 7,3 mm KELLER AG für Druckmesstechnik CH-8404 Winterthur +41 52 235 25 25 info@keller-druck.com HEX 27 Viton Flat Seal KELLER Ges. für Druckmesstechnik mbH DE-79798 Jestetten +49 7745 9214 0 eurocenter@keller-druck.com Viton O-Ring Seal o Copper-Washer G 1/2" o G 3/4" Edition 03/2017 Subject to alterations Companies approved to ISO 9001 www.keller-druck.com
