一般說明

The "FLPTU", designed by EDIBON, allows the student to configure a flow, level, pressure and temperature control system, apart from studying the fundamentals of the control engineering on which they are based.

The "FLPTU" unit consists of a hot water circuit, a cold water circuit and a heat exchanger that transfer the heat between both circuits.

In the cold water circuit the three phase pump impels the water from the supply tank to an upper tank equipped with a pneumatic controlling valve that it is used as actuator of the flow, pressure, level and temperature control loops.

In the hot water circuit, a circulation pump makes water flow through a heating device and the heat exchanger. The heating device can be used as an actuator for the temperature control loop. In addition, the temperature of this circuit can also be regulated by controlling the flow that circulates through the cold water.

The "FLPTU" unit includes different types of sensors to close the control loops, the unit includes flow meter sensor, ultrasonic level sensor, differential pressure sensor, pressure sensor and temperature sensor in order to perform the four types of control loops with different actuators and sensors to give the students a complete understanding of process control theory.

The "FLPTU" unit allows to use the industrial controller, included in the supply of the unit to perform the level, pressure, temperature and flow control loop. The PID parameters of the industrial controller can be modified through the front panel of the device. During the practical exercises the student will understand the procedure to perform all the stages of a PID control loop, measure of the physical measurement with a sensor, signal conditioning, program the controller device, configure the set point value and adjust the PID parameters to perform an appropriate control of the process.

The "FLPTU" also allows to perform the control of the level, temperature, pressure and flow with the optional EDIBON PLC unit, not included in the "FLPTU" supply. There are available the PLC models of different manufacturers: PANASONIC, SIEMENS, OMRON, MITSUBISHI, ALLEN BRADLEY, etc.
