K70502 Oxidata™ Data Acquisition Software Package


 

Test Method
The RBOT procedure employs severe oxidation conditions to rapidly determine oxidation stability. Suitable for both new and in-service oils, the RBOT method is applicable to many types of petroleum oils. The sample is oxidized in the presence of water and a copper catalyst in a stainless steel pressure vessel under an initial pressure of 90psi (620kPa). Pressure inside the vessel is recorded electronically or mechanically while the vessel is rotated at 100rpm at constant temperature, and the amount of time required for a specified drop in pressure is the oxidation stability of the sample. A variation of the RBOT method is the “Thin Film Oxidation Uptake Test” (TFOUT) for gasoline automotive engine oils.

Features and Benefits
• Electronic pressure measurement systems exclusively designed for RBOT, TFOUT and other ASTM oxidation test methods

• Powerful Oxidata™ software for Windows® environments

• Monitors up to twelve pressure and four temperature channels

• Real-time average bath temperature display

Can be installed to most manufacturer’s RBOT/TFOUT test apparatus


 

K70502 Oxidata™ Data Acquisition Software Package
Complete electronic measurement systems for plotting pressure versus time and temperature in RBOT and TFOUT testing. Each system includes transducers, bomb couplings, RTD probe assembly, multiplexer, data acquisition card, software, and mounting and connecting hardware. Systems are available in two, three and four pressure vessel configurations, and additional channels can be added for up to a total of twelve pressure and four temperature channels.

Koehler pressure measurement systems for RBOT and TFOUT feature Oxidata™, a high accuracy pressure measurement software package designed exclusively for ASTM oxidation test methods. Designed to run in a Windows® environment, Oxidata™ monitors up to twelve samples simultaneously, with graphical or tabular display of results. Each channel can be independently configured for any of the applicable ASTM standard test methods without compromising the independence or accuracy of the other channels. Independent start and stop times and user programmable end points add even greater flexibility.

The software plots your data on screen on line, real time, and automatically saves your data on disk or to the hard drive during the test to prevent loss of valuable data. Multiple display options include the ability to view the status of all twelve pressure channels on screen simultaneously and then click on any one channel for a graph display; or to view four channels in graphical format simultaneously. Powerful program features allow you to change axes, have colored plot lines and zoom in on a specific plot sector to view data in greater detail.

Oxidata™ Features and Specifications
• On-line, real time monitoring of up to twelve samples simultaneously - results plot directly to the screen for instant monitoring or printout of results

• Menu options for RBOT or TFOUT testing, as well as for other ASTM fuel and lubricant oxidation tests

• Programmable automatic end point detection with graphical and tabular representation

• Each channel can be configured and operated independently with different start/stop times and different ASTM test methods

• Zoom in feature allows for magnification of any plot sector on any channel for a more detailed study

• Monitors and reports temperatures of as many as four baths simultaneously using accessory RTD’s, and calculates and displays average temperature for each bath. Exports data to spreadsheet programs such as Microsoft Excel®, Lotus 1-2-3®, etc.

• Temperature and pressure calibration capability

• Data is saved directly to the disk or hard drive during testing to prevent loss of valuable data

• Operates in Windows® environments

• Simple upgrade from existing Koehler data acquisition systems
