Monty - Basics of the test set up. National instruments data acquisition system cDAQ-9172 plus national instruments modules that measured the outputs of the sensors.
MontySensorsRPM- Honeywell Speed sensor Electro 3010anThe rpm sensor works by the action of a magnet and the teeth of a gear passing by. The movement of the magnet causes a sine wave output of the sensor who’s frequency is a measure of the number of teeth passing by. The gear we had has 60 teeth on it so it automatically provided an output of RPM.Inlet Pressure Transducer OmegaPressure difference transducer Px771-100wdiThermocouples J-type omega
Lo - This was the Preliminary testing to find the flow rate of the air supply of the system.
Raj - This was the preliminary test results for the RPM of the systemThis test came after a disappointing visual test conducted as soon as assembly was complete.The primary reason for the early disappointment was increased friction on the bearings due to extra precautionary measures, especially resulting from the bearing stop.
Raj- This slide shows the sensors we used and that they were hooked to lab view. This slide shows also shows general test.
Lo - This graph shows that the Rpm increases as the pressure was released from the air tank.When the air supply was shut off after the max rpm was reached the rpm linearly decreased which shows that their isn’t much air drag in our system.
