Description
TH2 Pressure Measurement And Calibration Didactic Equipment Vocational Training Equipment Thermal Lab Equipment

DESCRIPTION
A bench top 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.


TECHNICAL SPECIFICATIONS
Operating range of Deadweight Pressure Calibrator: 20 kN/m² – 200 kN/m²
