- Computer controlled solenoid valve to evacuate the Unit: ATENG 11575
condensed steam in the condenser.
Three regulation valves to regulate the steam inlet, the condensed outlet and the refrigeration water.
- Instrumentation:
- Two pressure sensors: one sensor situated in the steam inlet line, range: 0 – 10 bar and other
- sensor situated in the upper side of the condenser, range: -1 – 1.6 bar.
- Force sensor (load cell) to measure the force of the brake, range: 0 – 20 N.
- Speed sensor to measure the speed of the turbine shaft, range: 0 – 20000 rpm.
- Flow sensor to measure the refrigeration water flow, range: 0.25 – 6.5 l/min.
Level sensor to measure the condensed steam volume in the condenser.
Five “J” type temperature sensors. They are situated in the steam inlet line, in the upper and lower
side of the condenser and in the condensation water inlet and outlet lines.
The instrumentation allows to measure the braking torque, turbine power, steam mass flow and
specific heat (kg required to obtain a kW).
- The unit is equipped with safety devices: a pressure switch, a safety valve for the condenser and
PMMA protection screens.
- The complete unit includes as well:
Advanced Real-Time SCADA.
Open Control + Multicontrol + Real-Time Control.
Specialized Control Software based on LabVIEW.
National Instruments Data Acquisition board (250 KS/s, kilo samples per second).
Calibration exercises, which are included, teach the user how to calibrate a sensor and the
importance of checking the accuracy of the sensors before taking measurements.
Projector and/or electronic whiteboard compatibility allows the unit to be explained and
demonstrated to an entire class at one time.
Capable of doing applied research, real industrial simulation, training courses, etc.
Remote operation and control by the user, as well as remote support from technical
support, are always included.
Totally safe, utilizing 4 safety systems (Mechanical, Electrical, Electronic & Software).
Designed and manufactured under several quality standards.
Optional ICAI software to create, edit and carry out practical exercises, tests, exams,
calculations, etc. Apart from monitoring user's knowledge and progress reached.
This unit has been designed for future expansion and integration. A common expansion is
the Scada-Net (ESN) System which enables multiple students to simultaneously
operate many units in a network.
- Required elements (Not included):
- ATENG 12019. Steam Generator (6 kW) (for high pressures and high temperatures).
