BENTLY 133396-01
Product introduction
The BENTLY NEVADA 133396-01 is a high-performance Keyphasor sensor cable assembly, engineered to transmit precise rotational position signals between Keyphasor proximity transducers and 3500 series Keyphasor monitor modules like the 3500/25 149369-01. As a critical link in machinery monitoring systems, it ensures the integrity of Keyphasor signals—essential for synchronizing vibration, speed, and position measurements in rotating machinery.
This shielded cable assembly is designed to minimize signal degradation and electromagnetic interference (EMI), which can corrupt the high-frequency Keyphasor signals used to track shaft rotation. Its robust construction and precise impedance matching make it ideal for industrial environments where reliable signal transmission is vital for accurate machinery diagnostics. Whether in power plants, refineries, or manufacturing facilities, the 133396-01 plays a key role in maintaining the performance of 3500 series monitoring systems.
Core advantages and technical highlights
Superior signal integrity: The 133396-01 features a 50Ω impedance-matched design that ensures optimal signal transmission between Keyphasor sensors and monitor modules. This minimizes signal reflection and attenuation, even over the full 3-meter length, preserving the accuracy of phase and speed measurements critical for machinery diagnostics. In applications like turbine monitoring, where phase angles must be measured within ±0.2 degrees, this signal integrity is indispensable.
Advanced EMI shielding: Equipped with double shielding (foil + braid) with 95% coverage, the cable effectively blocks electromagnetic interference from nearby motors, power lines, and industrial equipment. This shielding is grounded at both ends to create a continuous barrier against noise, ensuring that the weak Keyphasor signals (typically millivolt-level) remain uncorrupted. In electrically noisy environments like steel mills, this prevents false speed readings or phase shifts that could lead to incorrect diagnostic conclusions.
Extreme environment durability: The cable’s jacket and insulation are rated for operation from -55°C to +125°C, allowing it to perform in cryogenic or high-temperature industrial settings. It resists oils, fuels, and common solvents, making it suitable for use in refineries, chemical plants, and offshore platforms. Unlike standard cables, which may crack in cold temperatures or soften in heat, the 133396-01 maintains flexibility and electrical performance across its entire temperature range.
Precision connectors: The BNC connectors on the 133396-01 are precision-machined to ensure secure, low-loss connections with both Keyphasor sensors and 3500/25 series modules. They feature gold-plated contacts to minimize corrosion and signal resistance, even in humid or salty environments. The connectors’ locking mechanism prevents accidental disconnection, a critical feature in vibration-prone areas like pump rooms or compressor bays.
Typical application scenarios
In small-scale power generation facilities using the 3500/25 149369-01 Keyphasor monitor, the 133396-01 cable connects proximity transducers on turbine shafts to the monitor module. Its shielding protects against EMI from generator alternators, ensuring accurate speed measurements that enable the 3500/33 149986-01 vibration monitor to perform reliable order analysis. This helps detect rotor imbalance or bearing wear in biomass or solar thermal plant turbines.
Within water treatment plants, the 133396-01 links Keyphasor sensors on pump shafts to the 3500/25 149369-01 module. Its chemical resistance makes it suitable for installation in areas with exposure to water treatment chemicals, while its EMI shielding prevents interference from variable frequency drives (VFDs) used to control pump speed. This ensures precise tracking of pump rotational speed, critical for detecting cavitation or impeller wear.
In food and beverage processing facilities, the cable connects sensors on mixer and conveyor shafts to Keyphasor monitors. Its compliance with RoHS standards and resistance to cleaning agents makes it safe for use in hygienic environments. The secure BNC connections prevent contamination from moisture or debris, ensuring reliable speed monitoring that maintains product quality and processing consistency.

Relationship with 3500/25 149369-01 and other modules
The 133396-01 is specifically designed to complement the 3500/25 149369-01 Keyphasor monitor module, serving as the critical signal link between Keyphasor sensors and the monitor. Its impedance matching and shielding properties are optimized for the 1Hz – 20kHz frequency range of the 3500/25 149369-01, ensuring that the module receives clean, accurate signals for speed and phase calculations.
Beyond the 3500/25 149369-01, the cable is fully compatible with other 3500 series Keyphasor monitors like the 4-channel 3500/25-01-01-00. It also works seamlessly with 配套的 Keyphasor sensors such as the 330103-00-05-10-02-00, forming a complete signal chain from sensor to monitor. When paired with vibration monitors like the 3500/33 149986-01, the 133396-01 ensures that the synchronized data required for order analysis remains accurate and reliable.

Installation, handling and maintenance instructions
Installation preparation: Before installing the 133396-01, power off the 3500 series rack and Keyphasor sensors to prevent signal damage. Ensure the installation path is free of sharp edges, excessive bending, or contact with high-voltage cables (which can induce noise). Required tools include a BNC torque wrench (set to 0.5Nm) and cable ties for secure routing.
Installation steps: Connect one end of the 133396-01 to the Keyphasor sensor’s BNC port, tightening with the torque wrench to ensure a secure seal. Route the cable along a path that minimizes exposure to EMI sources (e.g., motor cables) and avoid tight bends (minimum bend radius: 50mm). Connect the other end to the 3500/25 149369-01 module’s BNC input, again using the torque wrench. Secure the cable with non-metallic ties to prevent movement in vibration-prone areas.
Maintenance suggestions: Inspect the 133396-01 quarterly for signs of damage, including jacket cracks, connector corrosion, or shielding exposure. Clean connectors with isopropyl alcohol and a lint-free cloth to remove dirt or oxidation. Check that shielding grounds are secure at both ends. If signal degradation is detected (e.g., erratic speed readings on the 3500/25 149369-01), test the cable with a network analyzer to verify impedance continuity. Replace damaged cables immediately to maintain monitoring accuracy.
