ZHT series piston type pressure gauge is my company according to the national latest "piston type pressure gauge verification regulations" (JJG59-2007) require new research and development design and manufacturing.Due to the key components of the piston pressure gauge with high hardness and low temperature coefficient of linear expansion of tungsten carbide material, so as to improve the wear resistance of the piston, therefore under pressure after deformation (negligible), minimum performance is very stable.The working medium of piston adopted sebacate diisooctyl, so that the pressure gauge has a very high sensitivity.
The adoption of new materials, new technology, new process, so the new technical indicators of piston manometer
Greatly improved.Which is widely used to test digital pressure gauge, precision pressure gauge, pressure transmitter, pressure sensor and other instruments.
Second, the performance characteristics:
1. The pistons and piston cylinder adopt high strength, high hardness, and low temperature linear expansion coefficient of the carbide tungsten carbide materials carefully made, grinding, wide working temperature stable performance of 20 + / - 5 ℃.
2. Load low center of gravity, weight through the hanging basket directly on the piston, piston smooth operation, little pressure fluctuation, the accurate value.
3. More than 25 mpa pressure transfer medium using viscosity small sebacate diisooctyl, thus ensuring pressure gauge with high sensitivity.
4. Weight 0.05 for carbon steel materials used for the pressure gauge, a magnitude 0.02 above are all made of non-magnetic stainless steel making.
5. The pistons work position with the displacement sensor monitoring, piston stroke of 0 ~ 3 mm, instrument display has the advantages of quick, eye-catching, accurate.
6. Wide range, the lower limit of 1 mpa, the basic error of plus or minus 0.02% or + / - 0.05%.
7. Pressure regulating light energy, even in the 100 mpa pressure can also be at ease.
Third, main technical parameters
1. The measurement range and measurement accuracy level
At ambient temperature (20 + 2) ℃, temperature fluctuation is not greater than 0.5 ℃ under the condition of its measurement accuracy level see the table below
