The Electronic Pitot Sensor was designed as an accessory for the Computer Linked Air Flow Bench. Measuring connections on the sensor are connected to the pressure sensors on the Bench, the measurements made in this way enable the pressures across the diameter of the tube (= travel) to be displayed. The position of the measuring opening in the tube is output by a potentiometer as a voltage signal and can be displayed in a software package as travel in mm. With the vertically moving sensor, pressure measurements in the intake tube for the fan on the can be performed.

It allows the students performing study and experimentation concerning the driving of a step motor, unipolar or bipolar. The rotation can be performed with increments of a single step or with continuity, at a variable speed. This board is designed to provide a valid support for the study of the operation and of the application criteria of these important electro mechanical components. Position and direction are indicated by a disk. An LCD display allows showing the number of steps, the number of turns, the rpm, the rotation direction and the selected parameters of the controller.

The Oil Pump Supply Module is part of an equipment series that facilitates the investigation of a wide range of engines and machines. The flow is adjusted on a pressure valve and recorded using an oval wheel meter. Other sensors measure the temperature, intake and delivery pressure. Different oil pumps can be operated on the supply module and investigated in terms of their characteristic behaviour. The corresponding sensor connections and digital displays are located on the measuring equipment block. The pumps are connected into the experimental set-up using hydraulic hoses with quick action couplings.
