Product Description

APPARATUS FOR PRESSURE GAUGE CALIBRATION

A benchtop unit designed to introduce students to pressure, pressure scales and common devices available to measure pressure.
The equipment utilises a Deadweight Pressure Calibrator (DPC) to generate a number of predetermined pressures. This is connected to a Bourdon gauge and electronic pressure sensor to enable their characteristics, including accuracy and linearity, to be determined.
The DPC consists of a precision ground piston and cylinder with a set of weights giving an operating range of 20 kNm-2 to 200 kNm-2.
The Bourdon gauge and pressure sensor are mounted on a manifold block with a separate reservoir to contain the hydraulic fluid (water for safety and ease of use). Valves enable easy priming, restricted flow of water to demonstrate the application of damping and the connection of alternative devices for calibration.
It allow to calibrate the gauge envelope provided in the bench and other pressure gauges with similar measuring range,
Brass calibrated cylinder mounted on a support,
A stainless steel piston with a cross section of 1 cm²,
(100 mm²) is on the brass cylinder,
In the upper part of the piston a platform to place other weights,
The weight of the piston and the platform 5 N,
Other two weights supplied, respectively of 5 and 10 N,
On the support there two links: one and four receiving the fluid,
A vent hole which serves to prevent the piston cylinder is ejected by excessive pressure,
A series of tubes with different diameters supplied.
