PRODUCT DESCRIPTION
Proximity signal conditioning sensor
Bently Nevada 330780-91-CN is a Proximitor Sensor. The sensor conditions the signal from its compatible probe and extension cable. The complete calibrated chain supplies a voltage related to conductive-target position for machinery monitoring, with the selected electrical length, target material and monitor configuration checked together.
The selected configuration specifies 9 m calibration and din mounting. Match the complete probe and cable combination to this calibration before commissioning. Unresolved mounting, length, approval or modification fields must be confirmed against the delivered assembly; enclosure similarity is not evidence of interchangeability.

ACTUAL APPLICATIONS
Applications for 3300 XL 11 mm proximity transducer system
These applications describe manufacturer-documented family use. They do not establish that this exact ordering code was installed at a named customer site.
-
01 · THRUST POSITION
Longer-range turbine shaft measurements
The 11 mm family supports axial thrust-position measurements where its documented measuring range suits the target. The sensor conditions the compatible probe signal. -
02 · DIFFERENTIAL EXPANSION
Steam-turbine ramp measurements
The manufacturer identifies ramp differential-expansion measurements on steam turbines. Match the complete 11 mm sensing chain and ramp geometry to the configured monitor; do not transfer an 8 mm calibration to this application. -
03 · RECIPROCATING MACHINERY
Compressor rod-position monitoring
The manufacturer lists rod-position and rod-drop measurements on reciprocating compressors. The complete transducer chain and target arrangement must suit the configured channel rather than being chosen by a shared connector alone.

PROXIMITY SIGNAL CONDITIONING SENSOR
Integrating 330780-91-CN
The sensor conditions the signal from its compatible probe and extension cable. The complete calibrated chain supplies a voltage related to conductive-target position for machinery monitoring, with the selected electrical length, target material and monitor configuration checked together.
Use a matching 3300 XL 11 mm probe, extension cable and Proximitor Sensor. Upgrading a 7200 11 mm or 14 mm system requires all three sensing components and the appropriate monitor update; an existing 3300 monitor may require modification.
Install the correct electrically isolating mounting arrangement and connect the documented field wiring. Observe the sensor temperature range and appropriate barrier or non-barrier supply requirements. Operation at a supply more positive than -23.5 Vdc may reduce the available linear range.
Features:
- Match probe family, electrical length, target geometry, mounting and monitor configuration
- Follow the applicable installation instructions
- Confirm unverified configuration details
The 330780-91-CN Proximitor Sensor requires appropriate configuration before system integration and commissioning.
INTERCHANGEABILITY
Verify the complete replacement identity before commissioning
Replacement of 330780-91-CN requires comparing probe family, electrical length, target geometry, mounting and monitor configuration. A shared base family or similar appearance does not establish a drop-in replacement for the complete ordered assembly.
Use a matching 3300 XL 11 mm probe, extension cable and Proximitor Sensor. Upgrading a 7200 11 mm or 14 mm system requires all three sensing components and the appropriate monitor update; an existing 3300 monitor may require modification.
No verified exact-order discontinuation date, product revision or designated successor is asserted. Document revisions identify the reference literature, not hardware changes to the supplied product. Unconfirmed replacement options must be resolved before substitution.
Features:
- Preserve the complete ordering identity
- Compare the installed electrical and mechanical interfaces
- Do not infer hardware revisions or successor models
The 330780-91-CN Proximitor Sensor requires replacement verification against the complete installed configuration and current manufacturer documentation.

FREQUENTLY ASKED QUESTIONS
Questions buyers ask about 330780-91-CN
Direct answers about identity, compatibility, stock, warranty, payment and shipping.
-
What does 330780-91-CN identify?
The selected configuration specifies 9 m calibration and din mounting. Match the complete probe and cable combination to this calibration before commissioning. Unresolved mounting, length, approval or modification fields must be confirmed against the delivered assembly; enclosure similarity is not evidence of interchangeability. -
What is the role of this Proximitor Sensor?
The sensor conditions the signal from its compatible probe and extension cable. The complete calibrated chain supplies a voltage related to conductive-target position for machinery monitoring, with the selected electrical length, target material and monitor configuration checked together. -
Which sensing chain is compatible with 330780?
Use a matching 3300 XL 11 mm probe, extension cable and Proximitor Sensor. Upgrading a 7200 11 mm or 14 mm system requires all three sensing components and the appropriate monitor update; an existing 3300 monitor may require modification. -
Which machinery application is documented for this family?
The manufacturer identifies ramp differential-expansion measurements on steam turbines. Match the complete 11 mm sensing chain and ramp geometry to the configured monitor; do not transfer an 8 mm calibration to this application. -
What installation checks are required for this configuration?
Install the correct electrically isolating mounting arrangement and connect the documented field wiring. Observe the sensor temperature range and appropriate barrier or non-barrier supply requirements. Operation at a supply more positive than -23.5 Vdc may reduce the available linear range. -
Can the probe temperature rating be applied to the sensor?
No. The sensor operates from -52 to +100 deg C, with storage from -52 to +105 deg C. Probe and extension-cable environmental limits are separate and must not be used as the sensor limit. -
Does a matching enclosure prove this is a drop-in replacement?
No. Check probe family, total electrical length, target calibration, mounting and the monitor configuration. Use a matching 3300 XL 11 mm probe, extension cable and Proximitor Sensor. Upgrading a 7200 11 mm or 14 mm system requires all three sensing components and the appropriate monitor update; an existing 3300 monitor may require modification.
