A benchtop unit designed to introducestudents to pressure, pressure scales and common devices available to measurepressure. The equipment utilises a Deadweight Pressure Calibrator (DPC) togenerate a number of predetermined pressures. This is connected to a gauge and electronic pressure sensor to enable their characteristics, includingaccuracy and linearity, to be determined. The DPC consists of a precisionground piston and cylinder with a set of weights giving an operating range of20 kNm-2 to 200 kNm-2. The gauge and pressure sensor are mountedon a manifold block with a separate reservoir to contain the hydraulic fluid(water for safety and ease of use). Valves enable easy priming, restricted flowof water to demonstrate the application of damping and the connection ofalternative devices for calibration.
