Introduction; Principle Of Operation - SKF TMEH 1 Mode D'emploi

1. Introduction

The SKF Oil Check Monitor TMEH 1 measures the effect of contamination
and electro-chemical changes that occur in synthetic and petroleum
based oils. It is especially developed for engine oils but is also suitable for
gear and lubrication oils. The OilCheck is a portable instrument, which
offers a two-minute alternative to lengthy laboratory investigations.

1.1 Principle of operation

The SKF TMEH 1 detects and measures the dielectric constant of an oil.
By comparing the measurements obtained from used and unused oils
of the same brand, the SKF TMEH 1 is able to determine the degree of
change in the dielectric constant of the oil. Dielectric change is directly
related to the degradation and contamination level of the oil and helps the
user to optimise intervals between oil changes and to detect increased
mechanical wear and loss of the oils lubricating properties. To facilitate
trending the instrument is equipped with a numerical read-out.
