Built in hand pump
Large volume systems are easily primed.
Greatly speeds up priming and pressure generation.
Enables an effortless, small bore high pressure ram screw
to be fitted.
There is no additional valve operation involved.
Standard on Models M2800, M2820, M3800, and M3820
Motor drive
If a continuous pressure is required, a motor drive can be
provided to rotate the weights. Rotating the weights by
hand is satisfactory for standard calibrations.
The motor is isolated from the Deadweight Tester by a
thermal barrier, preventing warming of the measuring
piston. The motor is suitable for 210/250, 105/125 volts at
50/60 HZ, please specify requirement at time of order.
Not available on models M2800, M2820.

LIQUID
This is the most portable and flexible version of our
comparison test pumps. The unit utilises our standard
Deadweight Tester system. The piston and weights are
replaced by a second test station to which either a test
gauge, transducer or transfer standard is fitted for
comparison with the instrument being tested. A hand pump
is fitted giving the following benefits:
MODEL T1300
0 to 20000 psi
MODEL T1200
LIQUID
Tested with water and suitable for use with:
water, mineral/vegetable oil, alcohol.
Fitted with a reservoir and valve, pressure is quickly
generated with the ram screw.

Pressure is generated with the sensitive hand pump and is
vented with a fine control needle valve.

and vented with a fine control needle valve.
Model: T4200

Separators
GAS
LIQUID TO AIR
For high pressure pneumatic calibration, this unit interfaces with hydraulic deadweight testers, giving a rateless liquid to air
separation. A series of fluid traps ensures the instrument under test remains dry. Needle valves control the pressure, and the
deadweight tester ram screw controls the fluid level. Please specify if interface is for oil or water application.
Model: API5000/1
Model: API5000/2
Model: API5000/3
LIQUID TO LIQUID
This unit has a flexible "Viton" diaphragm, separating the
deadweight tester fluid and a non contaminating liquid.
Any liquid can be used that is compatible with "Viton" and
aluminium bronze. The unit also protects the deadweight
tester from contamination.
Model: T3600
Model: T3601
DIRT/MOISTURE TRAP
Protects pneumatic Deadweight Testers, when the
cleanliness of the instrument under test cannot be
guaranteed. The unit is mounted directly onto the test
station. Particles and moisture are trapped within the
body, which are visible on Model T4400.

ANGLE ADAPTOR
To calibrate back connection gauges, the angle adaptor fits
directly onto the test station, converting it through 90,
allowing the same adaptors to be used.

Two deadweight tester systems are built
into a single instrument with a crossconnecting valve. The two systems are
pressurised in parallel with the crossconnecting valve open, until both pistons and
weights are floating at the specific line
pressure. With the cross connecting valve
closed the differential pressure is generated by
each additional weight loaded to the measuring
piston. The balance piston remains floating,
ensuring that the line pressure is maintained.
