Pressure calibrator becomes full calibration system with embedded PC

April 2008 Pressure Measurement & Control

The Swiss instrument producer Huber Instrumente has added an embedded computer to its Automatic Pressure Calibrator ADK 4000. The automatic pressure controller becomes a complete calibration system, independent from any plant information infrastructure.

The core of the system is formed by the automatic pressure calibrator ADK 4000 composed of a measuring module with three ranges between 20 kPa and 70 MPa, a controller module with stepper motor operated needle valves for a precise control of the pressure without overshoot, and now the embedded PC/104. Besides the traditional interfaces, it carries a GPIB controller. In addition, only a monitor, a keyboard and a mouse are needed.

The software control from the integrated PC is optimally adapted to the hardware. Besides the semi-automatic calibration of analogue or digital pressure gauges, an additional module with a DMM permit the fully automatic calibration of pressure sensors and transmitters. The data can be displayed and printed locally or, if needed, transferred to superior information systems.
