KELLER Pressure – Swiss Made Quality

Outstanding Long-Term Stability
The piezoresistive measurement technology from KELLER Pressure represents high long-term stability and reliable measurement results over many years. The robust design, high proof pressure and proven sensor technology make the digital pressure gauges a reliable solution for demanding measurement tasks.

High compatibility
Various pressure connections, a choice of pressure units as well as digital interfaces and software solutions enable flexible integration into a wide range of applications. The high level of compatibility means the pressure gauges can be selected to suit the measurement task, environment and existing infrastructure.

Optimum accuracy
Depending on the model, the digital pressure gauges from KELLER Pressure offer a very high level of measurement accuracy and repeatability. This means they are suitable for both accurate reference measurements and demanding service and inspection tasks in an industrial environment.
 

Calibration certificate & test reports
At KELLER Pressure, all pressure gauges are calibrated for pressure and temperature. The calibration certificate included in the scope of delivery documents the high accuracy and low error band over the entire specified temperature range.

Note: Extended test reports are available on request.

Precision
At KELLER Pressure, a deliberate distinction is made between accuracy and precision. Accuracy describes the deviation from the actual pressure value. By contrast, precision describes the ability to present measured values in a highly stable and reproducible manner.
High precision means:

• consistent measured values without scattering
• reliable comparability of measurements
• reliable assessment of the smallest changes in pressure

High-precision variants, which can reproducibly present measured values in the range of up to 0,01 %FS, are available for selected versions. These high-precision versions are optional and not available for all products or configurations. Higher precision devices can be sent to external calibration laboratories (e.g. DakkS). Here, they are adjusted using more precise reference systems, enabling the existing precision to be converted specifically into correspondingly high accuracy.
