SenGenuity's ViSmart Viscosity Sensor Element Successfully Tested for Long-Term Reliability in Engine Oil Applications

ViSmart Sensor Element was successfully tested for Rotating Pressure Vessel Oxidation Test for Applications in Engines for Continuous, Real-Time Monitoring of Oil Condition

HUDSON, NH - January 28, 2008 - SenGenuity, a division of Vectron International, a leader in the design, manufacture and marketing of breakthrough sensor products and solutions, today announced that its ViSmart(TM) viscosity sensor element has successfully passed the Rotating Pressure Vessel Oxidation Test (RPVOT) for applications in engines for continuous, real-time monitoring of oil condition. The RPVOT is an ASTM 2272 test, which oxidizes the oil heavily, and is used to test the sensor's capability to survive oxidized oil conditions; these conditions are reflective of actual operating conditions in engines.

The RPVOT was conducted by OELCHECK GmbH, the world leader in lubricant analysis and related consultation. This activity is part of the working partnership between SenGenuity and OELCHECK. Under terms of that partnership, OELCHECK, as part of its overall oil condition monitoring and data analysis services, is conducting tests of the ViSmart sensor supported by their deep knowledge in tribology for customers in Europe.

"At OELCHECK, we are committed to providing our customers with information regarding leading edge technologies and products, as we work to help them effectively monitor the condition of their oil to reduce maintenance costs and improve productivity," said Paul Weismann, president, OELCHECK GmbH. "The RPVOT results show that the SenGenuity ViSmart viscosity sensor element itself can withstand the conditions of excessively aged modern engine oil without significant formation of deposits on the sensor surface. It is also not getting damaged at atmospheric pressure conditions at temperatures up to 150°C."

The ViSmart(TM) sensor element, manufactured in accordance with standard semiconductor practices and packaged in a standard T0-8 housing, was placed in a determined oil quantity after the oil was aged and oxidized used pressurized oxygen at 150°C. The test is carried out in a tightly controlled temperature environment and the sensor and oil are placed in a rotating vessel for 24 continuous hours. The sensor was analyzed at 4 hour intervals for surface coating integrity and packaging robustness. The successful test outcome clearly demonstrated that no significant sensor element surface degradation or material buildup had occurred in the excessively aged engine oil.

"SenGenuity is dedicated to providing our customers disruptive solutions which survive harsh environments," said Kerem Durdag, director of business development, SenGenuity. "The fact that our ViSmart(TM) viscosity sensor element successfully passed the RPVOT test is a testament to the sensor products' ability to satisfy stringent requirements in a wide array of oil condition monitoring applications."

SenGenuity's ViSmart viscosity sensor is designed to provide instantaneous sample and/or continuous, real-time, in-process viscosity measurements for embedded real-time, in-line environments requiring high resolution and accuracy in low- to mid-range viscosity fluids. The ViSmart viscosity sensor uses robust and reliable semiconductor technology, has no moving parts, and is sealed for complete immersion. It is unaffected by vibration or flow conditions, does not need field calibration and is packaged in a very portable, lightweight size. The ViSmart sensor measures a wide range of viscosity of fluid and is rated for temperatures up to 125˚C in a threaded bolt package for quick installation, with custom options and configurations available for specific industry applications and process requirements.

The ViSmart model series can be connected to any computer or control platform via the standard protocols and the forthcoming CANBUS and 4-20 mA options to provide a continuous audit trail for process monitoring markets to control operating costs and maintain quality standards. Additionally, leveraging SenGenuity's Starter Kit bench-top viscometer data station, the customer can acquire multiple channels of continuous viscosity and temperature data.
