HPX Calibrator - 1

High-pressure calibrator medium: hydraulic oil KELLER pressure calibrators are highly accurate calibration instruments which are available for the following pressure ranges: -0,85…10 bar (LPX), -0,85…25 bar (MPX) or 0…700 bar (HPX) (special measurement ranges are available on request). The high-pressure calibrator (HPX) is used to generate pressure in order to check and calibrate mechanical and electronic pressure measurement devices with the help of comparative measurements. The pressure generator is accommodated together with the pressure display in a functional housing. The pressure on a test object that is fitted to the calibrator can be built up quickly, and tracking is made easy thanks to the integrated display. Test objects with a G 1/4” thread can be connected directly to the pressure port for the test object. The pressure is built up and adjusted precisely via a screw compressor that is integrated in the device (medium: hydraulic oil). Measurement work is made easier by a wide range of functions, such as setting any desired pressure zero point, display of peak and trough pressure values, or leak measurements. Furthermore, the applied pressure can be displayed directly on a computer via the integrated interface (USB converter), after which it can be saved and processed or managed in any desired manner. The calibrator, including accessories, is supplied in a durable carrying case, making it ideal for assignments in the field. - Measurement accuracy: < 0,05% of the full pressure range - Measurement interval: 0,5 seconds - Pressure generation by means of hydraulic oil - Battery-powered (normal commercially available button-cell battery) - Battery lifetime: > 2000 h in continuous operation - USB interface converter: included in the scope of delivery - Ambient characteristics: 0…50 °C / 5…95% relative air humidity - CE compliant / RoHS compliant KELLER AG für Druckmesstechnik CH-8404 Winterthur +41 52 235 25 25 info@keller-druck.com KELLER Ges. für Druckmesstechnik mbH DE-79798 Jestetten +49 7745 9214 0 eurocenter@keller-druck.com Edition 05/2006 Subject to alterations Companies approved to ISO 9001 www.k
