The unit itself includes the electric drive motor with speed control, 2 pressure vessels for the compressor experiments, a measuring tank and a supply tank for the pump experiments and a protection cover. The intake and delivery pressure, temperature, motor speed and power are measured and displayed digitally. The modular system allows the investigation of different machines (reciprocating machines and turbo machines). The corresponding flow is measured indirectly and transferred to the PC data acquisition software. Each machine is mounted on a base plate, which can easily be fitted into the unit. It is powered by a belt drive. Hoses with quick-action couplings provide the supply lines.

Pressure variations are made by the rotary vane pump which is provided with needle valves at entry and discharge. A further valve is incorporated at the pump outlet with pressure tappings either side of it to enable differential pressure measurements to be made and plugs are supplied to blank off any connections not in use. The apparatus consists of a series of pressure/vacuum measuring instruments mounted on a wheeled bench with an electrically driven rotary vane pump to provide the necessary pressure and vacuum. The bench also includes a microprocessor based portable digital pressure calibrator for pressures between -1 and 10 bar. The measuring instruments include a sloping, liquid filled manometer reading pressure from 0 to 75mm of water, a vertical manometer reading from 0 to 200 mm of water, a manometer reading from 0 to 760 mm, a pressure transducer with analogue readout and a Bourdon tube gauge scaled - 1 to 2.5 bar for reading both pressure and vacuum.

Compression Flexural frame on mortar specimens, dual range:
0-15 kN for flexure tests complete with two pressure transducers used along with a digital concrete compression machine
0-250 kN for compression tests.
Radial compressors are used to compress gases. The experimental unit provides the basic experiments to get to know the operating behaviour and the important characteristic variables of radial compressors. A protective plate placed in front of the inlet of the intake pipe prevents larger objects from being sucked in or the clogging of the intake opening. The medium is sucked in axially to the drive shaft by the rotation of the impeller and flows through the impeller rotating at high speed. By means of centrifugal force, the medium is accelerated towards the outer edge and is compressed in this manner. The air flow is adjusted by a throttle valve at the end of the delivery pipe. The microprocessor-based measuring technique is well protected in the housing. The experimental unit is fitted with sensors for pressure, temperature and speed. The flow rate is determinated via differential pressure measurement on the intake nozzle.

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 equipment utilises a dead weight 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.
