The Control Cabinet is equipped with a PAC unit (Programmable Automation Controller) and Touch-Screen Control System with specific software designed in order to comply with different standards.
Recording and Data Logging of all main system variables is available on external memory drive (USB).
All the messages, alarms and information on the status of the system are displayed on the Touch Screen unit.
The Touch Screen Unit is directly connected to the I/O Unit where all the signals, coming from the measuring instruments, are collected and processed.
The main Page (Home Page) displays the complete information about the status of the system and the following process variables:
- Sample temperature
- Sample weight
- Sample height
- Differential pressure on sample bed
- Degree of reduction Rt
- Oven temperature
- Nitogen (purge gas) flow rate
- Reacting gas Mix flow rate
- Loading pressure over the sample
- Total Test time from the start of the reaction
All these variables are available also in a graphic format in which all parameters are displayed vs. time.
The system is equipped with an Electric Vertical oven of about 12 kW maximum power. The oven design includes 3 horizontal heating zone. Each heating zone is constituted by silicon carbide heating elements electrically connected in series.
A quartz tube is placed inside the oven to avoid any contact between the reaction tube and the heating elements. An external alarm thermocouple is placed in the refractory wall to monitor the oven temperature.
This thermocouple is connected to the safety temperature circuit in order to avoid any over temperature. The maximum allowed temperature is set to 1200 °C. The vertical electric oven is equipped with a precision weighing system with a resolution of 0,1 g and a full scale value of 32 kg.
Printing Tool - PC Software
At the end of the test procedure, a new file is stored in the external memory USB stick.
