Applications |
- Repeatability better than ±0.005% of reading
- Accuracy up to ±0.025% of reading and even better
using a DADT converter
- Dual volume control valve delivers high volume to
rapidly build pressure
- Vernier adjustment for fine adjustment of pump
pressure
- Re-entrant type piston and cylinder assembly
maintains accuracy as test pressure increases and
improves the spin and float times
- Single and dual-column versions. Conversion kits
available
- Enclosed piston/cylinder assembly for safe operation
- Available engineering units: psi, bar, kPa, kg/cm2

| AMETEK
applied technology: |
Overhung
weight carriers - minimizes side thrust on the
measuring piston and cylinder assembly resulting in
improved measurement accuracy.
Re-entrant
piston/cylinder - This design reduces the rate of
fluid leakage, thus increasing the time available for
calibration of instruments.
Dual
volume hand pump - This allows the pump to deliver
a high volume in order to rapidly fill systems and build
pressure. The low volume permits easy pumping at high
pressures and a more gradual approach to the point of
pressure calibration.
Positive overpressure protection - The vertical
movement of the measuring piston assembly is restricted by
a positive stop. This will prevent the piston from damage
caused by accidental removal of the weights while
pressurized. These stops are rated at the maximum tester
pressure. |

DEADWEIGHT TESTER TYPE T
These high accuracy deadweight testers are ideal for
laboratory or field use. The type T tester uses distilled
water or fluid compatible with 300 series stainless steel
and MONEL (including AAA tester oil). For applications up
to 15,000 psi (1,000 bar). An optional dual piston
lets you interchange piston/cylinder assemblies to extend
the pressure measurement range using the same weight set.
A kit is available for converting to a dual column tester. |

DUAL COLUMN
Separate columns are provided for high and low pressure
measuring piston/ cylinder assemblies. Range changes are
achieved using a built-in crossover valve that allows
three-point calibrations to be performed in seconds. It is
not necessary to purchase a second set of weights. Fill
fluids and pressure ranges are the same as type T single
column testers. |

HYDRALITE (HL) PORTABLE DEADWEIGHT TESTER
This extremely compact, self-contained portable tester
is designed for pressure ranges from 10-200 psi (1-15 bar)
up to 50-3,000 psi (5-225 bar). Accurate to ±0.05% of
reading, the unit features an easy-to-use screw pump with
ratcheting handle and re-entrant type piston/cylinder
assembly. This helps maintain accuracy as the test
pressure increases. Weights and piston assemblies are
interchangeable. The unit's AAA tester oil may be easily
inspected through the transparent reservoir. Compact
design in only 9 x 9 x 10 in (23 x 23 x 24.5 cm). Tripod
option available for field applications. |
