Fluke Calibration 6531 and 6532: E-DWT Electronic Deadweight Tester Kits

Description

A powerful, complete hydraulic pressure calibration system to cover a wide workload
• Pressure ranges available to 200 MPa (30,000 psi)
• ± 0.02 % of reading total one-year accuracy, 0.025 % for two years
• Low torque variable volume allows for pressure generation and control up to 200 MPa (30,000 psi) with minimal physical effort
• Built-in priming system to fill system with test fluid and purge unwanted air to assure smooth operation
• Unique test port design eliminates the need for PTFE tape or wrenches. Adapters included for 1/8 in, 1/4 in, 3/8 in and 1/2 in NPT, 1/8 in, 1/4 in, 3/8 in and 1/2 in BSP, M20 x 1.5 and M14 x 1.5
• Compatible with a wide range of liquids, including water. Vacuum fill kit included to fill the E-DWT with any compatible test medium
• AutoTest™, AutoRange, ready/not ready indicator, onboard data capture and storage, overpressure alarm, RS-232 remote interface and other advanced features to simplify testing, improve safety and prevent calibration errors and damage to equipment
• Optional foot switch accessory allows hands-free data collection when running AutoTests
• Rechargeable battery pack and transport case options for field operation

Fluke Calibration improved the hydraulic pressure calibration process with the introduction of E-DWT-H electronic deadweight tester. E-DWT-H is an electronic calibrator designed to deliver traditional hydraulic deadweight tester performance with digital measurement features and convenience. Some improvements.

offered by E-DWT-H include:
• No weights to load and unload, transport or send out for calibration
• Provides real-time pressure indication with no need to know and correct for local gravity or ambient temperature
• No piston-cylinder changes
• No significant sensitivity to level or vibration
• Able to set and read any pressure value exactly, no minimum increment limited by smallest available masses; perfect for applications that require setting a nominal pressure precisely on the device under test and measuring it, such as analog gauge calibration
• Operates in any unit of measure, switching easily from one unit to the next.

The E-DWT-H is at home in metrology and calibration labs, on the production floor or in the field. It can operate with a wide selection of test mediums, including Sebacate calibration fluid, mineral oil, water and other liquids. ± 0.02 % of reading total one-year measurement uncertainty rivals the best laboratory deadweight testers. High quality hardware allows easy system fill and prime, pressure generation and precise control up to 200 Mpa (30,000 psi). Premium performance is wrapped up into one compact, lightweight, transportable package. An optional battery/charger pack supports up to eight hours of operation away from line power, and an optional shipping/carrying case with handles and wheels allows for easy transport for field application.

High performance calibration made simple
Fluke Calibration electronic deadweight tester kits feature E-DWT-H configurations combined with
the accessories needed for a complete calibration system. Model 6531 options feature E-DWT-H configurations with a single quartz reference pressure transducer (Q-RPT) to offer percent of reading performance from 10 % to 100 % of device full scale. Model 6532 options feature an additional Q-RPT
to maximize workload coverage, with percent of reading performance from 1 % to 100 % of device full scale. An included vacuum fill kit allows the E-DWT to be filled with your choice of compatible fluid, while eliminating problematic air pockets from the test circuit. Also included is a test station adapter to mount just about any pressure device to be tested without using PTFE tape or wrenches. 6531 and 6532 kits provide all you need to perform high level hydraulic pressure calibration right out of the box.
