Description

Description dead weight tester suppliers

JY series piston gauge is our new R & D product manufactured according to the latest national "piston gauge" test procedures (JJG59-2007). The key components of piston gauge uses a tungsten carbide material with a high hardness and low
temperature coefficient of linear expansion, which improving the wear resistance of the piston,therefore only a little (negligible )deformation under the pressure,performance is extremely stable. Working medium with a piston isooctyl sebacate,
so pressure gauge with high sensitivity.
As a result of new materials, new technologies, new processes,the technical indicators of new piston gauge has been greatly improved. Thus widely used to test digital pressure gauge, precision pressure gauges, pressure transmitters, pressure sensors and other pressure instruments.

Advantages dead weight tester suppliers

	The piston rod adopts a mainstream structure with an outer diameter of 22 mm and a height of 30 mm tungsten carbide.It can be connected to the piston institutions of major metrology institutes ,which more easier for later calibration .		The piston rod adopts an integrated structure, and the outer diameter of the protection system is 10 millimeters. The concentricity is high and the piston system is stable. This structure is unique in China and very competitive. The material is tungsten carbide.
	The sealing ring adopts Taiwan's high-performance sealing ring, which can guarantee a longer service life.		Piston displacement indication system uses digital tube red high-definition display more intuitive, built-in adjustment button can be calibrated in real time piston high and low position.
	Hanging basket adopts high-strength space aluminum, which is not easy to be deformed, and the appearance of anodizing is beautiful.		The bottom plate is stamped into 6 mm steel plate ,it is non-welded structure. It has high strength and is not easily deformed. Appearance using sandblasted spray treatment, paint surface formation.
	The valve needle adopts a hard alloy welding structure, and the valve needle has a high hardness and is not easily damaged.		0.05 level with imported blackening liquid to ensure that the color does not fall off the rust, 0.02 using 304 stainless steel non-magnetic processing accuracy is more reliable.
	Pressure gauge fittings use quick connectors to tighten without a wrench, speeding up calibration.		The standard bubble uses 10' high precision to ensure that the piston system is completely level.

Features dead weight tester suppliers

1. The piston and cylinder are made of high strength, high stiffness, and low temperature coefficient of linear expansion of the carbide grinding tungsten carbide material , with a wide range of ambient temperature , stable performance 20 ± 5 ℃.

2. The load center of gravity low, weight by Cradle applied directly to the piston, the piston smooth operation, the pressure fluctuation is extremely small, accurate indication.

3. When pressure more than 25MPa ,the medium uses a small viscosity isooctyl sebacate, thus ensuring a very high sensitivity.

4. The weights used are all non-magnetic stainless steel material.

5.The piston displacement sensor used to monitor the working position, the piston up and down stroke of ±1.5mm, instrument display is sensitive, smart, and accurate.

6. Wide range, at the lower 1MPa, the basic error of ± 0.02% or ± 0.05%, a KY100 type manometer, capable of reaching the upper limit of the current domestic 6,60,100MPa three measuring manometer.

7. pressure regulator easy , even at 250MPa pressure could ease.
