HPZ series Dead Weight Tester

Description

The main and auxiliary piston pressure gauge is a high accuracy pressure standard, which is mainly used for the verification of the piston area. It generally consists of a piston system, two sets of special weights, and a pressure calibrator.

Measuring Range

(0.04~0.6) MPa; (0.1~6) MPa; (1~60) MPa; (2~100) MPa.

Accuracy Class

±0.05%; ±0.02%; ±0.01%; ±0.005%

Piston System Material

Piston rod: Tungsten carbide

Piston cylinder: Tungsten carbide

Weight material

Carbon steel (±0.05% class); non-magnetic stainless steel (±0.02% class;±0.01% class; ±0.005% class);

Working medium

Transformer oil and kerosene mixed oil or sebacate

Dimensions

Length*Width*Height: (660 X 500 X 450)mm

Features

The material of piston rod and piston cylinder is tungsten carbide, which has the characteristics of high strength, high hardness and low temperature linear expansion coefficient, which improves the wear resistance of the piston and extends the life of the piston.

The change of the working position of piston adopts the liquid crystal display, and the observation is more intuitive.

The weight has been corrected for pressure deformation coefficient and local gravity acceleration.

Optional display function, including working parameters such as temperature, displacement, time, speed, pressure, etc.

The piston system is of modular design, and the module can be unscrewed directly when it is sent for inspection, without carrying a heavy mainframe.

It can be used for the verification of the piston pressure gauge, and can also be used as a high-precision pressure test standard. Optional kg weight and MPa weight.

The high-pressure piston weight adopts a hanging basket structure with a low center of gravity and excellent stability.

Using a quick pressure connector, it is easy to disassemble and install the inspected meter.

All indicators are in full compliance with JJG59-2007 "Piston Pressure Gauge", JJG99-2006 "Weight", and national metrological verification regulations, and each can issue a "Verification Certificate".
