Description

The principle of the bench is to study the axial and radial conduction.

The axial conduction can be studied on different diameters and different materials such as brass and stainless steel.

The radial conduction is studied on a disc

The robust design of this equipment makes it perfectly suited for use in schools.

Its anodized aluminum structure on multidirectional wheels with brakes makes it extremely robust as well as a great flexibility of integration into your premises. The manufacturing of this equipment meets the European machine directive.

A: PCT010 axial conduction unit

The unit is installed on a steel plate with handles equipped with four anti-slip feet.
It consists of a cold source consisting of an insulated D25 mm brass cylinder equipped with cold water circulation and a hot source consisting of an insulated D25 mm brass cylinder equipped with electrical resistance. Each source is instrumented by 3 thermocouple type temperature probes.
The module offers the possibility to test different samples:
-a D25mm brass cylinder insulated and instrumented by 3 thermocouple type temperature probes
-a brass cylinder D15mm insulated and instrumented by 3 temperature probes thermocouple type
-a stainless steel cylinder D25mm insulated and instrumented by 3 temperature probes type thermocouple

B: Radial conduction unit PCT011

The unit is installed on a steel plate with handles equipped with four anti-slip feet.
It consists of a brass disc with a diameter of 110 mm and a thickness of 3 mm, isolated from the outside.
The disc is heated in its center by an electrical resistance and cooled on the outer perimeter by a circulation of water.
The disc is instrumented by 6 thermocouple temperature probes distributed over its radius.

C: Measurement and control module with data acquisition PTC001

The module is installed on an aluminum profile structure equipped with four anti-slip feet.
It has safety features: general power disconnector and 30mA differential circuit breaker.
On the side, connectors are used to connect the conduction test modules (probes, resistance control output, etc.).
The front panel includes the buttons for starting the system and a 7" touch screen for displaying all measurements (element temperatures, heating power, etc.). the module has a WIFI router for connection to a computer. Data acquisition software is provided and is license-free.
