    The Kapteos eoProbe measures one component of the electric field vector based on the electro-optic technology. This Ultra-Wide Band sensor allows accurate measurements in almost any location and environment (air, liquids, gases, vacuum) under harsh conditions. Each eoProbe is delivered with a Routine Test report valid for 2 years. This probe must be used with the eoSense converter.

    Types of eoProbes:

    Transverse type: the eoProbe measures the concerned E-field vector when it is orthogonal to the eoProbe

    Longitudinal type: the eoProbe measures the concerned E-field vector when it is in line with the eoProbe

    Main advantages

    Vector near and far E-field measurement

    KAPTEOS_SAS_Vector near and far E-field measurement
    Thanks to its high performances, the eoProbe can measure both near and far E-field.

    No impact on the measured E-field

    KAPTEOS_SAS_eoProbe No impact on the measured E-field

    The eoProbe construction does not include any metal parts, hence the measured electric field is not perturbated. The eoProbe measures the exact E-field.

    Fully insulated probe

    KAPTEOS_SAS_eoProbe_Fully insulated probe

    Without any metal elements inside the probe, eoProbe is fully insulated. It is then possible to measure E-field under very high potential (several kV).

     

    Ultra-Wideband

    KAPTEOS_SAS_eoProbe_Ultra-Wideband

    Thanks to its technology based on Pockels effect, the probe can measure E-fields from 10 Hz up to 50 GHz with an excellent linearity.

     

    High resolution and compactness

    KAPTEOS_SAS_eoProbe_High resolution and compactness

    Its high compactness and sub-millimetric spatial resolution allows to measure very precisely the E-field.

     

    Outdoor operation

    KAPTEOS_SAS_eoProbe_indoor-outdoor-measurement

    Even under outdoor conditions (0 to 50°C for the probe), E-field measurement can be performed with good results.

     

    Accessories for the eoProbeeoPod for eoProbe sensors

    KAPTEOS_SAS_eoPod for eoProbe sensors

     

    This accessory allows via its articulated arm to maintain the probe on a specific location. It is fully dielectric, hence it can be used near E-field sources.
    2 versions are available:
    • One for air and vacuum probes
    • One for bio probes

    EOP-SH Ring to maintain 2 or 3 probes in the same direction

    Kapteos EOP-SH Ring

    The EOP-SH Ring is attached to the eoProbe to allow 3 probes to measure all 3 axis (X, Y and Z) of an electric field.

    The EOP-SH Ring is clearly marked to identify the orthogonal components of the vector for the transverse probes. 2 transverse probes and 1 longitudinal probe can be used with this ring. The ring material does not perturbate the measurement.

    eoLink Fiber optic extension

    KAPTEOS_SAS_eoLink_Fibre optic extension

    The fiber optic extension is inserted between the eoSense converter and an eoProbe sensor to increase the distance up to a maximum of 100 meters. A rugged version for outdoor usage is available in standard.

    KAPTEOS_SAS_eoVac vacumm feed-through for eoProbe

    eoVac Standard Setup
    Kapteos removable vacuum feed-through eoVacTM allows you to use air line electric (E) field probes eoProbeTM in a vacuum chamber when low to medium vacuum down to 0.5 hPa (or mbar) is sufficient.

     

    eoVacTM presents the main following advantages:

    • no additional insertion loss,

    • easy to operate,

    • low cost in comparison with any other vacuum optical feed-through.
