This high-precision sensor monitors the relative thermal growth of a machine casing relative to its structural foundation. Operating on a stable DC voltage interface, the assembly delivers real-time position measurements to prevent binding, structural deformation, or critical clearance losses during thermal transitions.\u003c\/p\u003e\n\u003cp\u003eDesigned to survive severe industrial environments, the \u003cspan style=\"color: #ff0000;\"\u003e\u003cstrong\u003e135613-01-00\u003c\/strong\u003e\u003c\/span\u003e converts physical displacement into a highly linear +1 to +6 Vdc analog output signal. The internal sensor architecture features an optimized 0.20 V\/mm scale factor operating over a 25.4 mm measurement envelope. It relies on robust internal components that maintain measurement repeatability despite continuous heat exposure, physical vibration, and aggressive industrial background noise.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eGlobal PLC Spare HUB's Insight\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eTurbine instrumentation engineers specify the \u003cspan style=\"color: #ff0000;\"\u003e\u003cstrong\u003e135613-01-00\u003c\/strong\u003e\u003c\/span\u003e due to its structural linearity and exceptional mechanical endurance. Large steam and gas turbines generate extreme ambient heat that can induce massive thermal drift in standard linear displacement sensors. This Bently Nevada assembly limits non-linearity to less than 0.25% of full scale while managing a temperature coefficient of 0.05%\/°C maximum. This high thermal stability ensures that structural tracking data remains accurate across severe heat cycles, allowing plant operators to execute cold start profiles without risking false displacement alarms.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: Bently Nevada\u003c\/li\u003e\n\u003cli\u003eModel: \u003cspan style=\"color: #ff0000;\"\u003e\u003cstrong\u003e135613-01-00\u003c\/strong\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eProduct Type: High Temperature Case Expansion Transducer Assembly (DC)\u003c\/li\u003e\n\u003cli\u003eInput Power Requirement: +13.5 to +26 Vdc unregulated, 30 mA minimum current draw\u003c\/li\u003e\n\u003cli\u003eAnalog Output Voltage Range: +1 to +6 Vdc linear output across all models\u003c\/li\u003e\n\u003cli\u003eLinear Measurement Range: 25.4 mm (1.00 inch) continuous stroke\u003c\/li\u003e\n\u003cli\u003eScale Factor Sensitivity: 0.20 V\/mm (5.0 V\/inch) constant output slope\u003c\/li\u003e\n\u003cli\u003eFrequency Response (-3 dB): 200 Hz typical dynamic tracking band\u003c\/li\u003e\n\u003cli\u003eMeasurement Stability: 0.125% full-scale retention\u003c\/li\u003e\n\u003cli\u003eNon-Linearity Metric: Less than 0.25% full-scale deviation\u003c\/li\u003e\n\u003cli\u003eTemperature Coefficient Rate: Maximum 0.05%\/°C (0.028%\/°F) thermal shift limit\u003c\/li\u003e\n\u003cli\u003eOutput Noise Baseline: Less than 10 mV peak-to-peak residual noise\u003c\/li\u003e\n\u003cli\u003eOperating Temperature Limits: -25 °C to +85 °C (-13 °F to +185 °F) operational ambient\u003c\/li\u003e\n\u003cli\u003eStorage Temperature Envelope: -55 °C to +125 °C (-67 °F to +257 °F) protected storage\u003c\/li\u003e\n\u003cli\u003eMechanical Shock Rating: 250 g peak deceleration pulse for 11 ms duration\u003c\/li\u003e\n\u003cli\u003eVibration Tolerance: 10 g peak structural acceleration across 0 to 2 kHz spectrum\u003c\/li\u003e\n\u003cli\u003eCore End Thread Specification: 6-40 UNF-2B precision thread layout\u003c\/li\u003e\n\u003cli\u003eMachine End Thread Specification: 1\/4-20 UNC-2A industrial mount thread\u003c\/li\u003e\n\u003cli\u003ePhysical Net Weight: 2.3 kg (5.0 lbs) structural weight\u003c\/li\u003e\n\u003cli\u003eEnclosure Outer Dimensions: 88.9 mm Height x 117 mm Width x 241 mm Length (3.50\" x 4.60\" x 9.50\")\u003c\/li\u003e\n\u003cli\u003eSensor Body Metrics: 171 mm Length, 19.2 mm Diameter, 65.4 mm from Body End to Null Center\u003c\/li\u003e\n\u003cli\u003eInternal Core Structural Length: 87.6 mm (3.45 inches) active core length\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eConfiguration Breakdown\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe alpha-numeric suffix structure of the \u003cspan style=\"color: #ff0000;\"\u003e\u003cstrong\u003e135613-01-00\u003c\/strong\u003e\u003c\/span\u003e designates the specific mechanical and physical options integrated into the transducer assembly:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e135613\u003c\/strong\u003e - Base Assembly Type: High Temperature Case Expansion Transducer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e01\u003c\/strong\u003e - Linear Range Option: 25.4 mm (1.0 inch) active displacement range paired with a 127 mm (5.00 inch) extension rod\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e00\u003c\/strong\u003e - Spring Mechanism Option: Standard assembly built without a spring return block\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eDiagnostic Capabilities \u0026amp;
