WATER TEMPERATURE CONTROL BENCH HTBE-C

This system consists of an operative part and an electrical cabinet integrated to the frame:

HTBE C

- The operative part permits to heat and to cool a water tank,
- The electrical cabinet receives the control plate wired by the student.

This system is water self contained and only need a main power supply 230V.
The bench allows to study, then to wire by the student, a complete temperature control system.
Following the version of the electrical plate it allow to study :
- Instrumentation (transmitter, thermostat, controller,...)
- Power modulation (static relay, wave train, dimmer...)
- Electric and thermal measurement.
The bench is conformed to the last securities standards.

 

Teaching objectives

- Setting and functioning checking,
- Wiring of an heating system,
- Measurement of electric and physical sizes: current, voltage, temperature,
- Control of characteristic sizes of the installation: voltage, current,
- This system can be used for electrical authorization,
- Setting of the loop control parameters,
- After wiring the electrical plate, the student interconnect the electrical plate to the system, then configure and check the good working of the whole control system.

 

Technical specifications

 

OPERATIVE PART :
The bench is made out of an aluminium frame on castors including:
- A 25 litres tank
- A immersed electrical heater
- A temperature sensor,
- A " low level" sensor,
- A security thermostat,
- A stainless steel centrifugal circulation pump,
- An aero-refrigerant.

The cooling circuit is made out of a circulation pump and an aero-refrigerant allowing to increase the exchange of calories between the water and the ambient air. It permits to be water self contained. Its purpose is double:
- To disturb the temperature control loop,
- To cool the water tank in order to restart a new experiment (without having to wait for the natural water cooling).

OPTION : data acquisition system
The data acquisition system is proposed in option. It is made out of a data acquisition card to place into a PC computer and a software functioning under Windows ®. This software allow to visualize the sizes in real time and to record them. The card is linked to the bench by the help of a plug on the front side of the electrical cabinet door.
