Water Temperature Control Bench

Water Temperature Control Bench

Description of:

Water Temperature Control Bench

• 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.

Dimensions

• 1150 x 670 x 1470 mm

Essential requirements

• Electrical power supply: single phase 230 V+T 16A.
