HPS Series Double Piston Pressure Vacuum Gauge

Description

The double piston pressure vacuum gauge is a measuring instrument that uses the principle of hydrostatic balance (that is, the fluid pressure acting on the effective area of the piston is balanced with the gravity of the load) to achieve force balance through a simple piston and a differential piston. It generally consists of two separate piston systems, special weights, and pressure calibrator.

Weight material

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

Working medium

Mixed oil of transformer oil and kerosene

Dimensions

Length*Width*Height: (680 X 500 X 450)mm

Features

It has two sets of piston systems, one set is vacuum piston and the other set is positive pressure piston, equipped with corresponding two sets of weights.

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 the piston adopts the liquid crystal display, and the observation is more intuitive.

The rotation of the piston is driven by a motor, which saves time and effort.

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.

All indicators are in full compliance with JJG 159-2008 "Dual Piston Pressure Vacuum Gauge Verification Regulations", JJG99-2006 "Weights", National Metrology Verification Regulations, and each can issue a "Verification Certificate"
