dead weight tester pressure gauge calibration
Description dead weight tester pressure gauge calibration
The Piston Dead Weight Tester is an essential tool for calibrating
pressure measurements. It functions as a standard calibration
device, using a piston cylinder mechanism to apply a load and
establish equilibrium with the pressure below the piston. These
testers are considered primary standards, meaning that pressure
readings derived from them are based on fundamental quantities such
as length, mass, and time.
Most often found in calibration laboratories, dead weight testers
play a crucial role in calibrating pressure transfer standards,
including electronic pressure measuring devices. By providing a
reference pressure traceable to fundamental physical quantities,
dead weight testers ensure the accuracy and reliability of pressure
measurements across a wide range of applications.

Advantages dead weight tester pressure gauge calibration
Feature china dead weight tester pressure gauge calibration
- The piston and cylinder are constructed from tungsten carbide, a
material known for its high strength, high stiffness, and low
coefficient of linear expansion with temperature. This ensures
stable performance across a wide ambient temperature range of 20 ±
5°C.
- The load's center of gravity is low, and the weight is applied
directly to the piston through a cradle, resulting in smooth
operation of the piston, minimal pressure fluctuation, and precise
indication.
- For pressures exceeding 25MPa, a medium with low viscosity, such as
isooctyl sebacate, is used to maintain very high sensitivity.
- All weights utilized are made of non-magnetic stainless steel,
ensuring no interference from magnetic fields.
- A piston displacement sensor is employed to monitor the working
position, allowing for a piston stroke of ±1.5mm up and down. This
results in an instrument display that is sensitive, intelligent,
and accurate.
- The instrument has a broad range, with a basic error of ± 0.02% or
± 0.05% at the lower end of 1MPa. The KY100 model manometer can
reach upper limits currently available domestically: 60, 100MPa in
three measuring ranges.
- Pressure regulation is straightforward, allowing for easy
adjustment even at high pressures up to 250MPa.
