Description

The 10 Gram Tube data logging equipment when used in conjunction with the Protected Laboratory Controller / Programmer and the Pressure Monitor Trip offer a complete system for 10 Gram Tube screening tests. A full system would also include a 2 Kilowatt Thermal Stability Oven, oven hood, framework with counter weights and Carius Tubes.

Associated Instrumentation.

Temperature Control

The rate of oven temperature rise is programmable and controlled by the M&C Laboratory Protected Controller. Over temperature trip facilities are an integral feature of the controller.

Pressure Monitoring

As the oven temperature rises, the pressure within the Carius tube may start to increase, this is monitored by the Pressure Trip Monitor Unit, via a transducer. An analogue output voltage proportional to the measured pressure is made available for logging purposes.

Data Acquisition

The system comprises of a DataScan acquisition module supporting eight thermocouple inputs, two of which are used for sample and oven temperature logging in this particular application. The DataScan module also supports up to 8 analogue inputs, one being used to log the pressure signal made available at the Pressure Monitor Unit. All data collected by the DataScan Module is transferred between the acquisition module and PC via a RS232 link.

Orchestrator Software

The DataScan module is supported by Orchestrator software. Orchestrator software is used to configure and calibrate individual Data Scan channels.

Orchestrator provides data trending, printing and logging. Logged data uses comma separated variables (CSV) format ready for automatic input to Excel. Text data may be printed via WordPad or Notepad while graphs can be printed via the Orchestrator software.
