Measuring system EPSILON+ for the determination of dielectric fluid properties

Unser Dielektriksensor EPSILON+

 

New Challenges in the field of fluid research and electric driveline development

Due to the advancing electromobility, lubricant and operating liquids need to meet new requirements regarding their dielectric properties. Modern synthetic or gear oils are not perfect isolators – even most of the oils used for the classic combustion engine are already characterized by a minimum level of electrical conductivity. This helps to decrease tension once overvoltages occure which are for example caused by static charging within gears.

Electric drives is now literally creating a new field of tension for oils. In the presence of high voltages and high frequencies, knowledge of the complex fluid impedance is useful in order to assess the performance of the fluid.

In addition to e-mobility, there are numerous other application areas for the EPSILON+. The knowledge of dielectric characteristics such as the relative permittivity or the dissipation factor tan δ is also relevant for the development and operation of transformers and electro-technical large-scale applications in which for example oils are used as coolant.

With EPSILON+, flucon presents a powerful measuring system for capturing the essential dielectric parameters of fluids.

 

flucon's latest innovation:

The dielectricity sensor EPSILON+

EPSILON+ is a compact laboratory measuring device that is used for the precise measurement of the complex fluid impedance, based on DIN EN 60247. The system determines the following parameters:

  •  electrical conductivity
  •  relative permittivity / dielectric constant   ε r
  •  dielectric loss factor tan δ

 

EPSILON+  //  Measurement

EPSILON+ is characterized by its operator convenience. Less than 10ml fluid quantity are sufficient for the measurement set-up of the screw-in sensor. The sample is filled into the supplied stainless steel container and brought to the desired test temperature with the help of a thermostat (optionally available). A full temperature gradient can then be executed automatically by the system according to your set limit values.

EPSILON+  //  Features

  •  determination of the complex fluid impedance
  •  high accuracy and repeatability
  •  wear-free stainless steel screw-in sensor
  •  integrated temperature measurement (PT100)
  •  evaluation electronics in compact table housing with LC Display
  •  EPSILON+ PC software for control and measurement evaluation included

 

E is for enhancement.
