Retractable Process Adaptions (Housings)

Retractable housings from METTLER TOLEDO are available in a variety of models to suit specific process and user requirements. They allow easy and safe insertion and withdrawal of electrodes/sensors without interruption of the ongoing process. Particularly suitable for processes which tend to cause sensor contamination or which run over extended periods.

Features and Benefits

• Intelligent sensor locking system – If no sensor is installed, no action is possible, preventing unwanted operation.
• Highly efficient cleaning chamber and large bore size design ensures particle/ dirt is flushed away.
• The complete retractable housing conforms with ATEX (94 / 9 / EC) directive requirements.
• Timesavings due to electrode/sensor maintenance and replacement without process downtimes.
• Versions with manual or pneumatic operation, as well as automated cleaning and calibration.
• Models for fully hygienic/sterile operations for process reliability.
• Versions with integrated sensor detector for enhanced safety.
• Process-independent maintenance, replacement and cleaning/(re-)calibration of electrodes/sensors without jeopardizing process safety, sterility/hygiene.

Various construction materials, process connections, and insertion lengths are available for the different housing product lines, providing excellent installation flexibility at the measurement point.

Housing design allows retraction of the sensor without interrupting the process: routine sensor maintenance, i.e. cleaning and calibration, can be performed anytime. The housings can be operated with EasyClean systems for programmable automatic sensor cleaning, flushing and calibration.

The housings are compliant with major international standards e.g. ATEX or FM approvals. An intelligent sensor locking system in InTrac781 and InTrac784 prevents unintentional housing operation without a sensor being present.
