Computer controlled ductility machine

The apparatus consists of a constant temperature bath capable to work in the range from -10 to 40 °C (thanks to a built-in cooling compressor) with an electrically powered tractor that pulls apart at an selectable speed the two ends of two briquet specimens: a load cell records continuously the force applied to the briquets transmitting them plus the bath temperature and the carriage speed to a PC through the RS-232 serial interface or USB port (converter required): a data acquisition software permits to display data on graphs, store them on the hard-disk, obtain printed reports and calibrate temperature, force and elongation sensors

Enamel finished steel case, floor mounted with swivelling castors.
Stainless steel bath, thermally insulated, with drain valve.
Chromium plated brass pump: it provides an adequate stirring of the liquid in the bath. Switch to turn it off during the test.
Stainless steel heater.
Microprocessor thermoregulator with PID action: built-in digital display 0.1°C accuracy. Probe: Pt100 RTD. Working range: from -10 to 40°C.
Safety device against overheating and low level with alarm lamp.
Built-in hermetic cooling compressor.
Acrylic hinged cover: it helps to maintain a constant temperature in the bath providing a clear view of the inside.
Traction carriage with variable speed motor: the carriage can contain 2 briquet molds. Automatic stop safety switch that stops the carriage when the maximum elongation has been reached. Traction length: 50, 100 or 150 cm.
White PTFE screen fixed to the bottom of the bath: it permits a better vision of the test while in execution.
Two load cells mechanically connected to the briquet molds. Range: 0 - 200 Newton: accuracy: 0.5 Newton.
RS-232 serial interface for the connection to a PC: we can supply the instrument with a traditional desktop PC or the user can use one of his PC’s with the requirements reported in the “accessories” section here below.
Data acquisition software running under Windows Xp/Vista/7: the software provides to record and show on graphs the force applied to the briquet molds, the elongation and the temperature of the bath. Data can be stored on a hard disk and printed. Software routines for calibration of temperature, force and elongation sensors.
Easy access control box containing all the electronics: anodized aluminium control panel with english written indications.
English written user manual with installation instructions.
For 220 V/50 Hz connections: 1800 W power consumption.
