A modern alternative to the traditional deadweight tester
E-DWT-H breaks new ground, improving the hydraulic pressure calibration process. E-DWT-H is an electronic calibrator designed to replace mechanical, piston-cylinder and weight based deadweight testers. It’s a lighter, easier-to-use deadweight tester alternative that is at home in the lab or instrument shop, as well as in the field performing in-situ calibrations and tests. This complete hydraulic pressure calibration system combines the convenience and precision of continuous, realtime electronic pressure measurement with the simple and direct operation of high quality operator controlled pressure generation hardware. E-DWT-H one year measurement uncertainty is ± 0.02 % of reading with ranges up to 30,000 psi. It can be configured to provide this uncertainty from its full scale down to 1 % of its range. Built-in pressure generation and control hardware allow the operator to fill and prime the system under test and generate and precisely adjust pressure throughout the range with ease.
Broad workload coverage
The E-DWT-H has the operational versatility to calibrate and test a broad range of pressure measuring instruments including:
AutoTest™ lets E-DWT operators quickly define test points and adjust all of the range-dependent settings with a single function.
The resolution and stability test used by the RPM4-E-DWT are set according to the range of the device under test. The upper limit setting is also set and provides range-based warnings and overpressure protection. While running AutoTests, the operator is prompted to set each sequential test point and test data is stored in the RPM4-E-DWT for recall or download. Typical test setup is quick and easy, but more complex tests can also be stored and reused.
Deadweight tester performance with digital measurement convenience
E-DWT-H offers precision, low measurement uncertainty and the stability over time of a conventional deadweight tester without the inconveniences associated with the piston-cylinders, weights, hand pumps, and interconnecting plumbing.
Versatility to cover a broad workload in a variety of environments
The E-DWT-H is at home in metrology and calibration labs, on the production floor or in the field. It operates with Sebacate calibration fluid, mineral oil, Skydrol® and other liquids. An optional battery/charger pack supports up to eight hours of operation away from line power.
All the features you expect in today’s state-of-the-art instruments, including:
Accuracy and performance
Ease of use
Automate data collection and manage calibration assets with COMPASS® for Pressure software
E-DWT can run stand-alone tests and collect test data. Test data can be downloaded over the RPM4-E-DWT’s RS232 interface.
The RPM4-E-DWT’s RS232 interface can also be used to run the E-DWT with COMPASS® for Pressure software or user developed software.
COMPASS® for Pressure software is universal pressure calibration software for the laboratory, which can be used to run simple or complex tests with multiple instruments. The user can create his/her own calibration report, and data can be exported to Fluke MET/CAL® Plus Calibration Management Software.
