The 27465-01 Valve Position Transducer utilizes field-proven, non-contact eddy current technology to continuously measure the mechanical stroke of steam turbine governor valves and control valves. Housed within integrated protective enclosures like the PROXPAC system, it operates by detecting the precise gap variance relative to a metal target block attached to the valve stem.
True Non-Contact Eddy Current Principle, Eliminating Mechanical Wear
High Linearity and Extreme Environmental Tolerance
The transducer system eliminates the need for physical connecting rods, thereby preventing mechanical wear and friction. The impedance changes captured by the probe are linearly converted into analog signals and routed to the Bently Nevada 3500/45 Position Monitor or 3300 rack for real-time closed-loop control and machinery protection. The electrical architecture of the 27465-01 maintains pristine signal integrity across long-distance cable runs between the turbine deck and the central control room.
Utilizing a specialized low-noise, dual-shielded coaxial integral cable, the transducer inherently suppresses common-mode noise, radio frequency interference (RFI), and electromagnetic interference (EMI) generated by high-power generator fields and nearby heavy-duty switchgear. The internal wiring provides precise impedance matching with Bently Nevada’s standard Proximitor sensors. This exact balancing guarantees that the high-frequency carrier signal remains free from phase shifts or attenuation, delivering an ultra-pure analog negative DC voltage loop where every millivolt corresponds accurately to fractions of a millimeter of physical valve movement.

Technical notes
Technical notes
The Bently Nevada 27465-01 Valve Position Transducer utilizes field-proven, non-contact eddy current technology. Safely housed within valve actuator assemblies or integrated enclosures like the PROXPAC system, it continuously measures mechanical travel. As the valve actuates, a metal target block linked directly to the valve stem moves relative to the probe tip, causing variations in the transducer's high-frequency electromagnetic field. These impedance changes are linearly converted into analog millivolt signals by a Proximitor sensor, which are then routed to a Bently Nevada 3500/45 Position Monitor or 3300 monitoring rack for high-precision, real-time closed-loop control and asset trip protection.
The 27465-01 is a high-precision, non-contact eddy current valve position transducer manufactured by Bently Nevada, primarily used to detect the mechanical stroke of critical industrial valves.
What is the primary purpose of the 27465-01?
Its primary purpose is to monitor the opening and stem displacement of critical valves, such as steam turbine control valves and regulating valves, in real time, linearly converting mechanical travel into electrical signals for the protection system.
How do you properly install and use the 27465-01?
The 27465-01 is typically installed within the valve actuator assembly or a PROXPAC integrated enclosure. To use it, position the probe tip facing a metal target block linked to the valve stem, and adjust the initial gap voltage to establish the measurement benchmark.
What operating principle does the 27465-01 utilize?
It operates on the principle of non-contact eddy current sensing. As the valve stem moves the metal target closer to or further from the probe tip, the alternating electromagnetic field changes, which the Proximitor captures and converts linearly into a voltage signal.
Which Bently Nevada monitoring systems is the 27465-01 compatible with?
It is fully compatible with legacy Bently Nevada 3300 systems as well as current 3500 condition monitoring systems, typically connecting to the 3500/45 Position Monitor module.
