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 eoProbe

 

eoPod 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.

EOP-HLD holder to maintain 2 or 3 probes at 90° to measure the 3 axis (X, Y and Z) of the electric field when using 3 longitudinal eoProbe. The holder 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.

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.
