RYC-TAG. Water Flow Temperature Control Module.

The “RYC-TAG” Water Flow Temperature Control module has been designed to study a practical

control system, through the control of water flow temperature.

The “RYC-TAG” module consists of two main components: the “RYC-TAG” apparatus and the “RYCTAG” interface box. The “RYC-TAG” apparatus contains all the sensors and actuators such

as temperature sensor, flow meter, water pump, etc. and the “RYC-TAG” interface box

contains all necessary components for power supplying, signal conditioning, etc.

The components are used in conjunction with the “RYC” unit to control the water temperature

of the cold water circuit, through the control of the water flow of the hot water circuit. Both

circuits are related by a heat exchanger.

The system allows to insert disturbances manually, through a manual valve that change the

water flow of the cold water circuit.

Specifications:

 Metallic structure.

 Reservoir Tank: 15 l.

 Level switch: level float switch sensor with an ON/OFF output.

 Water Pump: max. water flow 8 l./min.

 Manual valve to generate disturbances.

 Regulation valve control de the cold circuit flow value.

 Electronic Proportional Valve:

 Control input voltage: 0 to 3V.

 Aperture range: 0 to 100%.

 Analog flow meter:

 Range of measurement: 0-2 l./min.

 Temperature sensors:

 Transducer type: “J” type thermocouple.

 Output: 0.1 V/ºC.

 Heating element:

 Power consumption: 1500W.

 Control input voltage: ±10V.
