Safety Instructions
SensoGate WA 132
Process-Related Risks
Knick Elektronische Messgeräte GmbH & Co. KG assumes no liability for damages
caused by process-related risks known to the operator, which would in fact not permit
the use of the retractable fitting.
For your own safety, be sure to observe the following precautions:
Work on the retractable fitting shall only be performed by personnel authorized by the
operating company and specially trained for handling and operating the retractable
fitting.
Be sure to take account of the influences of humidity, ambient temperature, chemicals,
and corrosion on the safe operation of the retractable fitting.

The SensoGate WA 132 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 EU Type Examination
ean direCertificate. Compliance with the Europ ctives and standards is confirmed by the
nformity an E markiEUDeclaration of Co d the C ng.

Safety Instructions
SensoGate WA 132
Operation in Explosive Atmospheres
The SensoGate WA132-X is certified for operation in explosive atmospheres.
• EU-Type Examination Certificate KEMA04ATEX4035X
Exceeding the standard atmospheric conditions within the manufacturer’s specifications, such as ambient tem-
perature, process pressure and temperature, does not impair the durability of the retractable fittings.
Related certificates are included in the product’s scope of delivery and are available at www.knick.de in the cur-
rent version.
Observe all applicable local and national codes and standards for the installation of equipment in explosive at-
mospheres. For further guidance, consult the following:
• IEC60079-14
• EU directives 2014/34/EU and 1999/92/EC(ATEX)
Possible Ignition Hazards During Installation and Maintenance
To avoid mechanically generated sparks, handle the SensoGate WA132-X with care and apply suitable measures,
e.g., use covers and pads.
The metallic parts of the SensoGate WA132-X must be connected to the plant’s equipotential bonding using the
metallic process connection and the grounding connection provided for that purpose.
When components are replaced with genuine Knick spare parts made of other materials (e.g. O-rings), the infor-
mation given on the nameplate may deviate from the actual version of the SensoGate WA132-X. The operating
company must assess and document this deviation.
Electrostatic charging
The drive unit of specific versions of the SensoGate WA132-X contains housing components made of non-con-
ductive plastic. Due to their surface, the housing components may build up an electrostatic charge. To prevent
this charge from becoming an effective ignition source in Zone0, ensure that the following conditions are met:
• Highly efficient charge generating mechanisms are excluded
• Non-metallic components are cleaned with a moist cloth only
Mechanically generated sparks
Single impacts on metal parts or collisions between metal parts of the SensoGate WA132-X are not a potential
ignition source only if the following conditions are met:
• Possible impact velocity is less than 1 m/s
• Possible impact energy is less than 500 J
If these conditions cannot be ensured, the operating company must reassess single impacts on metal parts or
collisions between metal parts as potential sources of ignition. The operating company must implement suitable
risk minimization measures, e.g., by ensuring a non-explosive atmosphere.
Possible Ignition Hazards During Operation
When using non-water-based cleaning, rinsing, or calibration media with a low conductivity of less than 1nS/m,
electrostatic charging of internal, conductive components may occur. The operating company must assess the
associated risks and implement appropriate measures.
The sensors that are used must be approved for operation in hazardous locations. Further information can be
found in the sensor documentation.
Electrostatic charging
The wetted components of the SensoGate WA132-X process unit are made of non-conductive PTFE plastic. The
components can build up an electrostatic charge. To prevent this charge from becoming an effective ignition
source, ensure that the following conditions are met:
• Efficient charge generating mechanisms are excluded
• Process media are grounded and have a minimum conductivity of 10 nS/cm
If these conditions cannot be ensured, operation in Zone0 and Zone1 is not permitted.

Intended Use
SensoGate WA 132
Intended Use
The SensoGate WA 132 is a pneumatically operated retractable fitting. It allows sensors to be
immersed in and retracted from liquid media, e.g., for process analytics.
The SensoGate WA 132 retractable fitting allows:
•immersing and retracting the sensor under process pressure (retractable fitting)
•calibrating or adjusting the measuring system under process conditions
(pressure and temperature)
• cleaning the sensor in the running process (optional)
• replacing the sensor in the running process (in Service position)
•variable process adaptation by the customer
The retractable fitting is suitable for sensors with a sensor diameter of 12 mm and a PG 13.5
thread. The following sensors can be installed:
• sensor with solid electrolyte, 225 mm long
•sensor with liquid electrolyte, 250 mm long
Safe Use
If you are not sure whether the retractable fitting can be safely used for your
intended application, always contact Knick!
To ensure safe use of the equipment, you must observe the temperature and
pressure ranges given in the Specifications of this user manual.
