Type 1327D Pressure Gauge Comparator
PPLICATION
A
• For pressure generatiing applications
requiring a manually operated
hydraulic pump
FEATURES
• Operating Pressure: 0-10,000 psi
maximum (0-60,000 kPa)
• Operating Media:
- Standard: SAE 20 weight
automotive machine oil
- Optional: Phosphate-based or
glycol fluids; Distilled water for
oxygen service
• O-ring Material:
- Standard: Buna N (D Series)
- Optional: Ethylene Propylene
(DH Series)
• Reservoir Volume: Approximately
1.5 pints (0.7 liter)
Many calibration applications require only
a quick comparison to a master gauge,
without the need for a primary deadweight
standard. In these applications the
Ashcroft 1327D offers the ideal combination of a reliable pressure source and a
proven secondary standard.
The 1327D utilizes the same pump, tools,
box and accessories that are used in the
1305D deadweight tester. How ever,
instead of weights and pistons, the 1327D
employs from 1 to 4 Ashcroft model 1082
test gauges as comparison masters.
These gauges have a dial size of 4
1
⁄2 inch-
es and are accurate to 0.25%of span in
compliance with the requirements of
ASME (formerly ANSI) B40.1, grade 3A.
The Ashcroft 1082 Test Gauge makes the
1327D the perfect choice for the calibration of 1% F.S. industrial service gauges
where a 4:1 accuracy ratio must be maintained.
Like the 1305D, the 1327D is available in
versions to accommodate either petroleum
based oils or glycol and phosphate ester
based “hydraulic fluids”. In addition, the
1327D can be configured to operate with
distilled water for the calibration of oxygen
service gauges.
Lightweight and fully portable, the 1327D
offers maximum utility in one simple, compact and complete test set.
