Proximity Probe
The 3300 5mm probe improves upon previous
designs. A patented TipLoc* molding method
provides a more robust bond between the probe
tip and the probe body. The 3300 5mm system is
orderable with Fluidloc cable options for
preventing oil and other liquids from leaking out of
the machine through the cable’s interior.
Connectors
The 3300 5mm probe and 3300 XL extension cable
have corrosion-resistant, gold-plated brass
ClickLoc* connectors. These connectors require
only finger-tight torque (connectors will "click"),
and the specially engineered locking mechanism
prevents the connectors from loosening. The
connectors require no special tools for installation
or removal.
3300 5mm Probes and XL Extension Cables can be
ordered with connector protectors already
installed, or we can supply the connector
protectors separately for installation in the field
(such as when the cable must be run through
restrictive conduit). We recommend connector
protectors for all installations to provide increased
environmental protection7.
Notes:
1. A 5mm probe uses smaller physical packaging and
provides the same linear range as a 3300 XL 8mm
probe (ref 141194-01). The 5mm probe does not,
however, reduce the sideview clearances or tip-to-
tip spacing requirements as compared to an XL
8mm probe.Use the 5mm probe when physical (not
electrical) constraints preclude the use of an 8mm
probe, such as mounting between thrust bearing
pads or other constrained spaces. When your
application requires narrow sideview probes, use
the 3300 XL NSv* probe and extension cable with
the 3300 XL NSv Proximitor Sensor (refer to
Specifications and Ordering Information p/n
147385-01).
2. XL 8mm probes provide a thicker encapsulation of
the probe coil in the molded PPS plastic probe tip to
produce a more rugged probe. The larger diameter
of the probe body also provides a stronger, more
robust case. We recommend the use of XL 8mm
probes when possible to provide optimal
robustness against physical abuse.
3. A 3300 XL Proximitor Sensor is available and
provides many improvements over the non-XL
version. The XL sensor is electrically and
mechanically interchangeable with the non-XL
version. Although the packaging of the 3300 XL
Proximitor Sensor differs from its predecessor, its
design allows for the use of a 4-hole mounting base
to fit it in the same 4-hole mounting pattern and to
fit within the same mounting space specifications
(when the application observes the minimum
permissible cable bend radius). Consult
Specifications and Ordering Information (p/n
141194-01) or our sales and service professional
for more information.
4. Use of XL components with 3300 5mm Probes will
limit system performance to the specifications for
the non-XL 3300 system.
5. The factory supplies Proximitor Sensors that are
calibrated by default to AISI 4140 steel. Calibration
to other target materials is available upon request.
6. When using this transducer system for tachometer
or over-speed measurements, consult
http://www.GEmeasurement.com for the
application note regarding the use of eddy current
proximity probes for over-speed protection.
7. We provide silicone tape with each 3300 XL
extension cable. Use this tape instead of connector
protectors. We do not recommend silicone tape in
applications which will expose the probe-to-
extension cable connection to turbine oil.
