Product Description
High Accuracy Float Type Piston Dead Weight Tester From Shelok
Pneumatic Dead Weight Tester with compressed air or nitrogen gas as the pressure source, is a Aerodynamic load pressure meter that with precision float ball in pressure area of lower sphere working state for the effective area of the floating ball.The floating ball tester as a pressure resource of pressed air and Nitrogen. It is pneumatic loaded pressure calibrator to use the floating ball.
The tester is a kind of pressure Benchmark instrument, with nitrogen or instrument compressed air as energy. it's an ideal equipment that calibrate all kinds of high accuracy of pressure transmitter, differential transmitter and precision of pressure gauge.

Features:
1. Modularity: Piston and pressure generator system is fully modular structure, the various modules can implement a single function or a combination of work
2. Stability: hydraulic piston using low weights to ensure high reliability and stability.
Interchangeability: - any piston - sleeve unit
3. Piston - sleeve unit: made of tungsten carbide materials; other parts made of high quality austenitic stainless steel, which can effectively prevent deformation. There are six ranges for choose
(-0.1-0.25)MPa (-0.1-0.6)MPa (0.1-2.5) MPa
(0.1-6) MPa (1-60) MPa (1-100) MPa
4. Weight: Adopts demagnetization quality austenitic stainless steel
5. Rotational speed: in free rotation state, the rotational speed is related to the time, e.g. 60MPa product, after 30 minutes, the rotational speed is fromthe initial speed of the drops 33.0RPM to 24.8rpm. This also shows that the piston - sleeve gap pressure distribution is uniform.
6. Effective area: under normal atmospheric pressure and 20 ºC conditions, the piston - the average effective area of the cartridge unit, and pressure deformation coefficient can be measured by the reference gauge
7. Piston descending speed: in the range of 60MPa case, the relationship between the piston speed and the pressure drop is shown below. In the range of 100MPa case for all of the components, the rate of decline and the effective piston area of pressure become a linear relationship, the maximum rate of decline is less than 5μm/s. Maximum effective area changes is less than 0.0006mm2.
Applications
- Piston gauges are used to calibrate customer piston gauges and pressure sensing devices
