樂清E-DWT Electronic Deadweight Tester Kits-6531 and 6532-美國FLUKE
A powerful, complete hydraulic pressure calibration system to cover a wide
workload
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.
The E-DWT-H is
used in the lab or instrument shop or can be taken into the field for
performing in-situ calibrations and tests. This hydraulic pressure calibration
system combines a high performance electronic reference pressure monitor and
manually operated pressure generation and control hardware in a single, compact
and rugged package. E-DWT-H offers the ease of use and precision of continuous,
real time electronic pressure measurement with the simple and direct pressure
control of high quality manual pressure hardware. E-DWT is named “electronic
deadweight tester” because it is intended as a lightweight and easy to use,
modern alternative to conventional piston-cylinder and weight based deadweight
testers.
The E-DWT’s
electronic reference pressure monitor is a special version of RPM4, designated
RPM4-E-DWT. RPM4-E-DWT can be configured with one or two high precision quartz
reference pressure transducers (Q-RPTs) with ranges from 7 MPa (1 000 psi) to
200 MPa (30 000 psi).
The RPM4-E-DWT is
controlled locally by the operator using its front panel display, keypad and
optional foot pedal or remotely by a computer using ASCII character command
strings over its RS-232 interface.
RPM4-E-DWT uses an
AutoRange feature to automatically select the most appropriate Q-RPT and to
optimize the E-DWT-H setup to cover the desired range of operation. When two
Q-RPTs are included, a half-turn valve isolates and protects the Lo Q-RPT from
high pressure when the Hi Q-RPT is in use. Visual and audible indicators assist
the operator in setting the shut off valve correctly.
The E-DWT-H
includes the hardware necessary to fill and prime the system under test and
generate and precisely adjust pressure up to 200 MPa (30 000 psi).
The E-DWT-H can be
powered with an optional battery/charger pack for use in locations where AC
power is not readily available.
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.
