PRODUCT DESCRIPTION

The M&G 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

Laboratory accuracy

The M&G 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.

Traceable certification supplied
with each tester

FEATURES

Three accuracies available

These instruments are available in ±0.100%, ±0.025%,
and ±0.015% of reading. The accuracy stated is the over­all 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.

Re-entrant system

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 con­figuration. 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.

Specification Sheet

SS-2150-T

Protected piston/cylinder

The piston and cylinder assembly are enclosed in the col­umn 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 verti­cal 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

Small incremental weight sets are avaliable to provide
fractional output pressures. These are available for the
Type T deadweight tester in psi, bar, kPa and kg/cm2.
