Intended Use
SensoGate® WA 130 H Retractable Fitting
Intended Use
The SensoGate® WA 130 H pneumatic retractable fitting is used for installing a sensor for mea-
surements in liquids. The sensor can be cleaned, calibrated or replaced under process conditions
(pressure and temperature).
The modular concept allows simple installation, operation and maintenance.
The operator can exchange process adaptations or convert the fitting for the use with gel sensors
or liquid-electrolyte sensors.
The retractable fitting is suitable for sensors with an outer diameter of 12 mm:
• with gel electrolyte, length 225 mm, sensor head with PG 13.5
• with liquid electrolyte, length 250 mm
The SensoGate® WA 130 H retractable fitting allows:
• inserting and retracting the sensor under process pressure (retractable fitting)
• calibrating or adjusting the measuring system and cleaning the sensor in the running process
(different options available)
• replacing the sensor in the running process (in SERVICE position)
• variable process adaptation by the operator at any time
Take account of the influences of humidity, ambient temperature, chemicals and corrosion.
Safe use
If you are not sure whether the retractable fitting can be safely used for your intended
application, please contact the manufacturer.
To ensure safe use of the equipment, you must follow the instructions given in this manual and
observe the specified temperature and pressure ranges.
The SensoGate® WA 130 H retractable fitting has been developed and manufactured in compli-
ance with the applicable European guidelines and standards. Compliance with the European
Harmonized Standards for use in hazardous locations is confirmed by the EC-Type-Examination
Certificate. Compliance with the European guidelines and standards is confirmed by the EC
Declaration of Conformity.
Hygienic Design
With regard to hygienic design and sterilizability, the retractable fitting complies with the recom-
mendations of EHEDG. This was established and verified in the TNO report V7942 dated February
25, 2008. If required, the TNO report can be viewed or obtained from the manufacturer.
For hazardous-area applications, the sensors used must ensure proper separation of the ATEX
zones. When the retractable fitting is in SERVICE position and the SensoLock ring has been locked,
the sensor may be replaced within a Zone 0 hazardous location.
There is no particular direct hazard caused by the operation of the device in the specified
environment.
