Description Générale
The Computer Controlled Thermal Conductivity of Liquids and Gases Unit, "TCLGC", has been designed by EDIBON to allow the students to appreciate and understand the heat transfer process through any gas or liquid locked in a solid.
By the realization of the practices the student can determine the thermal conductivity of any gas or compatible liquid with the construction materials.
The Computer Controlled Thermal Conductivity of Liquids and Gases Unit, "TCLGC", consists of an aluminum cylinder, that forms the body of the unit, which has inside a variable power heating element and temperature sensors, one of them inside the own heating element. It also has a brass jacket that contains the test fluid and the refrigeration water.
The fluid, whose thermal conductivity is to be determined, fills the small distance of radial security between the body of heated aluminum and a jacket with cooled water. This space is small enough to avoid the natural convection of the fluid.
The aluminum body and the water jacket are concentric thanks to two "o" ring joints which seal the distance of security, and which allow easily and quick dismantling for cleaning.
The unit incorporates a water regulation valve, which allows the flow of water to be varied (a water flow sensor) and temperature sensors at the water inlet and outlet.
The connection and disconnection of the sensors have been made to be easy and comfortable.
This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
