An oil sample valve can be added to the installation to provide a point to sample the oil while the sensor is installed. See the pictures below for more information.
The attachment removes 80mm from the effective length of the probe. This is in addition to the ETE adapter which removes 40mm. So this would mean that:
- Short probe effective length =110mm
- Medium probe effective length = 195mm
- Long probe effective length = 280mm

Please take this into consideration when planning the installation. See EcoStruxure Transformer Sensor Planning Guide.
