The Type T Hydraulic Deadweight Tester offers laboratory accuracy in an
instrument that is designed to withstand an industrial environment.
These testers are designed to be primary pressure standards and are
available in several ranges and engineering units.
The Type T Deadweight tester is available in ranges to 1,000 bar (15,000
psi). This robust tester has been engineered to withstand the stresses
of daily operation in a manufacturing environment and still maintain its
accuracy and repeatability. The Type T is constructed of 300 series
stainless steel and Monel and is supplied with Buna N O-rings as a
standard unit. Viton and EPT O-rings are optional. This deadweight can
use a water/alcohol mix or hydraulic oils for the pressure medium.
These instruments are available in ±0.100%, ±0.025%, and ±0.015% of
reading. The accuracy stated is the over-all accuracy of the tester. The
accuracy takes into account linearity, hysteresis, and repeatability. It
would also account for intrinsic corrections. Site corrections are the
user’s responsibility and the unit will not perform as specified
without them. The testers are manufactured to either International
Standard Gravity of 9.80665 m/s2 or to a user specified local gravity. |

Re-entrant piston /
cylinders |
The Type T deadweight
employs a re-entrant type piston/cylinder assembly. This
design applies test fluid to the outside and inside of the
cylinder. Unlike a simple piston/cylinder, this
configuration reduces clearance between the piston and
cylinder as pressure increases. This reduces the rate of
fluid leakage and increases float time, offers the
technician more time for testing, and reduces the amount of
pumping necessary to sustain the fluid loss. |
|
Configurations |
There are two important factors in the
selection of the proper deadweight configuration for your
application: ranges and location. If you have applications
for a single range of tests, then a single piston/cylinder
model is a good choice.
However, if you have some high pressure and some low
pressure testing, the Type T is available with dual
piston/cylinder assemblies that are interchangeable and
operate using the same weight set (±0.100% and ±0.025%
accuracies) or utilize dedicated weight sets for each
piston/cylinder assembly (±0.015% accuracy).
If you have the need to use the tester in a location other
than a lab, you may need a smaller and more mobile
con-figuration. The single column configuration will be your
best selection. These are available with dual
piston/cylinder assemblies.
For the applications where the tester will be stationary,
the dual column configuration is a good choice for those
needing multiple ranges. These are supplied with two
piston/cylinder assemblies and both columns are installed
and ready for use. A selector valve is used to determine
which column is in service at any given time. |
|
Worldwide engineering units |
The M&G Type T deadweight
tester can be manufactured in four different engineering
units: psi, bar, kgt/cm2, and kPa. All of the different
engineering units are available in any of the
configurations. |
|
Pressure media |
Because the Type T is
manufactured using 300 series stainless steel and Monel, you
can use either hydraulic fluids compatible with the material
or a water/alcohol mixture. We also offer EPT and Viton®
o-rings as options. This increases your media options.
Additionally, we offer an isolation membrane to protect your
piston/cylinder assemblies from abrasive media. This
facilitates the use of other fluids as process media but
allows for the benefits of MGAAA oil within the column,
which preserves your calibrated parts. |
|
Overhung weight carriers |
Another feature of Type T
deadweight tester is the way that the weights are positioned
on the carrier. M&G utilizes an overhung weight carrier
design. This design employs a tube carrier that is
positioned over the column and onto the piston driver. The
center of gravity for the stack of weights is lowered,
reducing side thrust and friction; which lengthens the life
of the piston/cylinder assembly. This also improves
measurement accuracy. |
|
Protected piston/cylinder |
The piston and cylinder
assembly are enclosed in the col-umn of the tester. The
weight carrier floats on the piston driver preventing damage
to the piston/cylinder assembly. Additionally, the
piston/cylinder assembly is engineered with positive
over-pressure protection by restricting verti-cal movement.
This protects the assembly from damage in the event of
weight removal under pressure. |
|
Dual volume pump |
The Type T pump offers a dual
volume pumping feature that allows for large volume of fluid
to be added at low pressures to fill the system and increase
pressure rapidly. Once the system is filled, you can switch
the output volume to a smaller volume. This eases pumping
and also provides for finer control in higher pressure
ranges. The reservoir is kept at atmospheric pressure
meaning that you can also refill the tester during a
calibration run. |
|
Easy Leveling |
AMETEK floating ball testers
incorporate a bulls-eye level for reference when preparing
the unit for use. The tester also employs a 3-leg leveling
system which is more convenient and is superior to a 4-leg
system. |
|
Small incremental weight sets |
AMETEK floating ball testers, such as the
RK50 tester, incorporate multi-position ball valves for
both the inlet and outlet valve connections. These ensure
trouble free operation that is both fast and efficient. |
|
Easy Leveling |
Small incremental weight sets
are available to provide fractional output pressures. These
are available for the Type T deadweight tester in psi, bar,
kPa and kg/cm2. |
