FLOW- LEVEL - PRESSURE - TEMPERATURE CONTROL BENCH MP111M

- Control of water level in loop - Control of water flow by winnowing - Control of water pressure by winnowing - Control of water temperature, (piloting resistive charges per static power unit) - Control of water temperature with cascade on the flow

MP111MTeaching objectives

- Study of the closed loop system :

- stability conditions
- response to a level instruction
- influence of the parameters of control and the algorithm setting (TOR, P, PI, or PID) on the results
- Study of an open loop system
-Study of the characteristic curves of the system
- Study of a cascade control system

5 Process are possible:

1 - Level control :
Actuator : pneumatic valve
Sensor : pressure transmitter
Disruption : leak on the pipe , leak under the column.

2 – Flow control :
Actuator : pneumatic valve
Sensor : Electronic flowmeter
Disruption : leak on the pipe

3 – Pressure control :
Actuator : pneumatic valve
Sensor : pressure transmitter
Disruption : leak on the pipe

4 - Temperature control :
Actuator : immersion heater
Sensor : temperature probe
Disruption : by provision of cold water

5 - Regulation cascades of temperature/debit :
Actuator : pneumatic valve
Sensor : temperature probe at the ouput of the heater and electronic flowmeter
Disruption : leak on the pipe, variation of the heater’s power
