PIEZORESISTIVE PRESSURE TRANSMITTERS
ABSOLUTE-, GAUGE- AND DIFFERENTIAL PRESSURE
SERIES 23 / 25
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
· Series 25
Male pressure port
Accuracy 0,5%FS, optional 0,1 and 0,2%FS
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 applica-
tions. 13 nominal pressure ranges. Current or voltage output.
• 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’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.)
Sealed Gauge Pressure Transmitter (Zero at ≈ 1 bar abs.)
Vented Gauge Pressure Transmitter (Zero at atmospheric)
Differential Pressure Transmitter (wet / wet)
