The Bently Nevada 135613-01-01 is a High Temperature Case Expansion Transducer Assembly (dc) for Turbine Supervisory Instrumentation (TSI) applications. Case expansion (sometimes referred to as shell expansion) is the thermal growth of the machine case as it expands during machine startup and on-line operations. The transducer system uses an LVDT (linear variable differential transformer) housed in a weatherproof, protective housing to measure this thermal growth. A rod on the LVDT connects to the machine case; as the case grows, the rod moves inside the LVDT, and the transducer electronically conditions the signal for output to a monitor for display and alarming.

The 135613-01-01 Bently Nevada Case ExpansionTransducer Systems may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).
Bently Nevada 135613-01-01 Case ExpansionTransducer Systems Manuals, Datasheets, Drivers, Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
The 135613 high temperature design is engineered to meet TYPE 4 requirements. The system is typically mounted on the foundation at the opposite end from where the turbine casing is attached to the foundation, providing information about the growth of the machine case relative to the foundation. Case expansion measurements enable operators to determine whether machine conditions are exceeding expected temperature growth differentials and whether the machine casing and rotor grow thermally at nearly the same rate during startup.
 
  • Gas & Steam Turbines: Relays vital casing vibration metrics during rapid thermal and speed transitions
  • Centrifugal & Reciprocating Compressors: Insulates delicate sensor telemetry against high-frequency vibration and flow turbulence
  • Industrial Pumps & Motors: Identifies localized unbalance, structural misalignment, and early bearing defects
  • Fans & Blowers: Collects raw velocity data used for prognostic balancing and structural health validation
  • Chemical Processing: Fits environments requiring resistance to aggressive chemical vapors, corrosive oils, and solvents

Orientation: Mount the protective, weatherproof enclosure onto the machine foundation at the opposite end from where the turbine casing is anchored to the foundation. This ensures you capture the maximum relative thermal growth.Footprint Dimensions: The physical footprint spans 88.9 mm (3.50 in) in height, 117 mm (4.60 in) in width, and 241 mm (9.50 in) in length.Fasteners: Secure the main housing using the four supplied 1/4-20 UNC bolts, flat washers, and lock washers. Mount the base to a clean, flat, vibration-free plate or bracket.

FAQs

  • What is the Bently Nevada 135613-01-01?+
    The Bently Nevada 135613-01-01 is a high-temperature DC Linear Variable Differential Transformer (LVDT) case expansion transducer designed to monitor thermal growth in heavy-duty machinery.
  • Does this model include an internal spring return?+
    The standard "-00" suffix version does not feature a spring return, meaning the core must be physically attached to the machine casing to track movement in both directions.I
  • What is the primary function of this transducer?+
    It measures the absolute thermal growth (case expansion) of a machine casing relative to its foundation. This monitoring prevents mechanical stress, binding, or misalignment as a turbine heats up to operating temperatures.
  • What is the difference between the 135613-01-01 and 135613-01-00?+
    What is the difference between the 135613-01-01 and 135613-01-00?The final two digits dictate the spring option. The -01 version includes an internal spring return for continuous rod extension, while the -00 (or "-10") designates a model without a spring return.
