Safety Information
SensoGate® WA 130 H Retractable Fitting
Operation in Explosive Atmospheres
The SensoGate WA130H-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 WA130H-X with care and apply suitable mea-
sures, e.g., use covers and pads.
The metallic parts of the SensoGate WA130H-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 WA130H-X. The operating
company must assess and document this deviation.
Electrostatic charging
The drive unit of specific versions of the SensoGate WA130H-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 WA130H-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.

NOTICE!
Observe the general requirements of protection devices to prevent pollution of potable water
(EN1717) when drawing water from drinking water pipes.
We recommend installing a check valve on the water supply to protect the drinking water from
pollution.
We recommend installing a check valve on the water inlet e.g. on the water valve provided by the
customer or on the rinse connection of the retractable fitting (inlet to calibration chamber) to pre-
vent backflow of rinse or process medium or compressed air into the water pipe.
Suitable check valves made from different materials are available from Knick.

Function Description
SensoGate® WA 130 H Retractable Fitting
The pneumatically operated retractable fitting allows calibrating or adjusting the measuring
system and cleaning the sensor in the running process. For that purpose, the retractable fitting
can be moved between two positions using compressed air:
• PROCESS position: Sensor located in the process medium.
• SERVICE position: Sensor located in the calibration chamber.
In SERVICE position you can clean, maintain, calibrate or adjust the measuring system.
A control unit, such as the Unical® 9000, moves the probe to SERVICE or PROCESS position and
leads different calibration and/or cleaning liquids to the sensor located in the calibration chamber.
For operation of the SensoGate®, you must connect control air, rinsing or calibration media, and
the electrical check-back signal for display of the probe position with the SensoGate®.
There are two basic options for this.
In conjunction with the UNICAL® or UNICLEAN® electro-pneumatic controllers and the PROTOS®
measuring system, air pressure, rinsing, or calibration media, and the check-back cable are com-
bined in a single hose with just one plug connection (multiplug, in the following referred to as
media connection).
This media connection is installed on the SensoGate® together with the outlet hose.
When you do not use a probe controller (UNICAL® or UNICLEAN® and the PROTOS® measuring
system), you can connect the supply lines for control air, rinsing or calibration media and elec-
trical check-back with a free hose connection via an adapter (ZU 0742 / ZU 0733 / ZU 0734, see
Accessories Page 41).
These liquids leave the calibration chamber through an outlet hose, i.e. they are displaced from
the calibration chamber by following liquids or by compressed air.
To replace the sensor, you must move the retractable fitting into SERVICE position.
With Unical® 9000 probe controller, all media, control air and the check-back cable for position
indication of the probe are connected to the retractable fitting through a compact connector
(multiplug).

SensoLock
Optionally, the WA 130 H is equipped with a SensoLock ring. SensoLock securely blocks the
retractable fitting in SERVICE position. Turning the SensoLock ring to “LOCK“ position mechanically
locks the internal lift piston and thus prevents the retractable fitting from moving to PROCESS
position.
The SensoLock ring can only be turned in SERVICE position. In PROCESS position and all
intermediate positions the SensoLock ring is blocked.
This prevents operation errors. Before starting maintenance work or replacing a sensor,
you must activate SensoLock (LOCK) to:
• make sure that the retractable fitting is in SERVICE position.
• prevent that the retractable fitting is accidentally moved to PROCESS position.
Turning the SensoLock ring to
“LOCK“ position prevents the
immersion in the process when
the sensor has been removed.
(blocking the travel function,
safety function)
After the sensor has been
installed, you can unlock the
travel movement by turning the
SensoLock ring to “UNLOCK”.
