The PN-173123 is a critical hardware component designed for use within the Bently Nevada 3300 XL High Temperature Proximity System (HTPS).
SpringLoc spring-clamped terminal block
DIN rail compact horizontal mounting
Lateral mode analysis
The 3300 XL High Temperature Proximity System is used to protect and manage critical machines in your facility for increased safety and efficiency. It is also used for mode shape analysis when measurements are taken at the turbine mid-span location. Mode shape analysis is important for research and development of a new steam or gas turbine design or when troubleshooting an existing design. Mode identification probes provide lateral mode shape information which is extremely valuable for balancing rotating machinery and identifying faults such as shaft cracks, bearing failures, rotor-to-stator rubs and other machine problems.
This advanced transducer system protects and manages critical machines in your facility for increased safety and efficiency. It excels in making proximity measurements at hot bearing locations and severe high-temperature environments where conventional probes would fail. Furthermore, the system is widely utilized for lateral mode shape analysis at the turbine mid-span location, delivering valuable information for balancing rotating machinery and identifying critical faults such as shaft cracks, bearing failures, and rotor-to-stator rubs.

Thermal Power
Used for lateral vibration measurement and mode shape analysis at the mid-span of steam turbines, helping engineering teams optimize rotor balancing and identify shaft cracks early.
Gas Turbine Power
Installed at high-temperature bearing housing locations of heavy-duty gas turbines to continuously monitor shaft vibration and radial displacement under severe thermal radiation.
Nuclear Power
Monitors the continuous shaft vibration of critical high-pressure steam-driven boiler feedwater pumps in the conventional island to ensure uninterrupted cooling water delivery.
Natural Gas
Protects the gas turbines and centrifugal compressors at pipeline compression stations, operating reliably within external instrument enclosures from -51°C to +100°C.
Petroleum Refining
Tracks radial vibration and thrust displacement on high-temperature flue gas expanders to prevent catastrophic rotor-to-stator rubs caused by thermal expansion.
Coal Chemical
Monitors the main air compressors and oxygen/nitrogen boosters, where its SpringLoc terminals eliminate wire loosening caused by structural floor vibrations.
When installing and maintaining the PN-173123 Proximitor, ensure its housing operates strictly within the -51°C to +100°C range and remains completely isolated from the extreme thermal radiation of the probe end. To safeguard the sensitive internal signal circuitry, the system must be fully powered down before handling any coaxial connectors because hot-swapping is strictly prohibited.
A minimum clearance of 25 mm must be maintained around the housing and top connector to prevent sharp wire bends that could compromise signal integrity. Furthermore, the Proximitor model must strictly match the total system cable length configuration (5-metre or 9-metre specification). Mixing extension cables of mismatched lengths is strictly forbidden as it will cause immediate measurement sensitivity calibration errors.

Technical notes
Technical notes
Engineered for high-vibration industrial sites, the mounting pad features a compact horizontal DIN-rail configuration and integrates SpringLoc spring-clamped terminal blocks. These terminals replace traditional screw-type connectors to eliminate the risk of terminal loosening caused by continuous machinery vibration, thereby guaranteeing long-term wiring integrity and uninterrupted signal transmission. As a passive structural and wiring component, the pad provides reliable electrical isolation for the sensor and maintains stable physical properties across an ambient operating temperature range of -51°C to +70°C (-60°F to +158°F). This ensures that the overall HTPS system can dependably deliver its 3.9 V/mm (100 mV/mil) vibration and position signals from extreme +350°C turbine mid-span locations back to the master monitoring system.
PN-173123 is a hardware part number from Bently Nevada.
How do you physically install the PN-173123 proximitor sensor?
PN-173123 supports high-density, tool-free installation. It can be mounted directly onto a standard DIN rail or panel-mounted via its 4-hole mounting base.
How do you connect wires to the PN-173123 without screws?
PN-173123 features an advanced SpringLoc terminal block, which allows field wiring to be completed by simply inserting stripped wires without any special tools.
Does the PN-173123 housing require a separate isolation plate during installation?
No. The structural housing design of PN-173123 provides integral electrical isolation from the mounting plate, eliminating the need for separate isolator plates.
How does PN-173123 protect itself from electromagnetic or radio frequency interference?
PN-173123 features advanced RFI/EMI immunity and is fully CE compliant, meaning it requires no external metal conduit even when installed near high-power machinery.
