The floating motor is free to rotate and with a moment arm, rests against a load cell. Attached to the motor shaft is a coupling. The engineering drawing for the coupling mating half is supplied for the customer to produce.
Universal Drive Module Apparatus consists of a sturdy cradle, with bearings at either end. The motor is speed controlled using the control box supplied. The signal from the load cell is also fed directly into the control box. The torque being applied to the attached apparatus can be calculated using these parameters. The front panel of the control box has the speed control potentiometer, tachometer display for motor speed and the force display for the load cell signal. Suspended between the bearings is a motor, which gives drive to a variety of customer designed apparatus.

The apparatus, which is illustrated in Fig. 1, consists of a valve base and a bronze barrel which has a precision machined bore into which fits a stainless steel piston. Calibration of Pressure Gauges is used for the calibration of the Bourdon type pressure gauge supplied with the Cussons Hydraulic Bench and other gauges of a similar rating using the dead weight method. Fitted to the valve base are two connections and a blanking plug. A connection for the pressure gauge under test is pre-fitted and supplied with a length of plastic pipe suitable for connection to the pressure gauge via the auxiliary tapping on the Hydraulics Bench. The piston is fitted with a platform which can carry calibration weights the weights supplied with the apparatus are equivalent to pressures of 0.5 bar and 1 bar. The piston and platform have a total weight equivalent to 0.5 bar pressure. A non-return connection for the water supply from the hydraulics bench is fitted on one side of the valve block. A spill-pipe is fitted into the barrel which prevents the piston being ejected by excess pressure. The Bourdon gauge, fitted on the Bench, is a simple device and normally very reliable in service. On the third side of the block is a blanking plug which is removed to allow the apparatus to be drained of water. The apparatus is mounted on a plastic base for stability. After an extended period of use, slight deviations of value are likely to occur and for "accurate" work a calibration curve for the instrument is necessary. The basic element of the gauge is a curved, elastic-metal tube, usually of brass or stainless steel, which changes its geometry when filled with fluid under pressure. This distortion is transmitted by linkage to the gauge pointer. The dead weight tester is not subject to variations and can, therefore, be used as a reliable.
