Quick Detail

Description

The 16925-12 Sensor Proximity Probe Cable is a high-precision interconnection component designed specifically for Bently Nevada's legacy and specialized proximity transducer systems. As a critical Sensor Proximity Probe Cable, the 16925-12 ensures the seamless transmission of high-frequency eddy current signals between the proximity probe and the Proximitor* sensor. This 12 ft (3.7 m) extension cable is engineered to maintain signal integrity in demanding industrial environments, facilitating accurate measurement of vibration, axial position, and speed on rotating machinery. The 16925-12 Sensor Proximity Probe Cable is characterized by its low-loss design and precise characteristic impedance, which are essential for minimizing signal attenuation and phase shifts that could compromise machinery protection data.

Designed for durability and reliability, the 16925-12 Sensor Proximity Probe Cable features a robust insulation layer that is resistant to common industrial contaminants such as lubricating oils, moisture, and chemical vapors. This Sensor Proximity Probe Cable utilizes factory-installed threaded connectors that provide a secure, vibration-resistant link, preventing accidental disconnections in high-frequency oscillation zones. The 16925-12 is particularly valued in retrofit applications and specialized monitoring setups where specific cable lengths and impedance matching are required to maintain API 670 standard compliance. Its 50 Ω characteristic impedance ensures that the Sensor Proximity Probe Cable operates with minimal signal reflection, providing a clean data path for critical machine health diagnostics.

Applications

The 16925-12 Sensor Proximity Probe Cable is primarily used in the monitoring of fluid-film bearing machinery, such as large centrifugal compressors and steam turbines in power generation facilities. Its 12-foot length allows for flexible routing from the probe mounted inside the bearing housing to a junction box or Proximitor sensor located on the machine's exterior. It is essential for transmitting accurate radial vibration and axial position signals, enabling real-time detection of rotor instability and thrust bearing wear.

In the petrochemical industry, this cable is vital for monitoring high-speed pumps and gearboxes in hazardous areas. Given its CSA and ATEX certifications, the 16925-12 can be safely deployed in Zone 0 or Zone 1 environments where explosive gases may be present. Its resistance to oil and chemical exposure ensures that the vibration signal remains pure even in the presence of synthetic lubricants or process leaks, supporting predictive maintenance and reducing the risk of unplanned downtime in critical production loops.

The 16925-12 also serves as an indispensable timing and speed measurement link in complex machinery setups. When paired with a Keyphasor* probe, the cable facilitates the transmission of precise timing pulses to diagnostic instruments. This allows engineers to perform sophisticated phase analysis and shaft centerline plotting. The cable’s ability to withstand temperatures up to +200°C makes it particularly effective for monitoring high-temperature equipment where standard cables might melt or degrade, ensuring consistent data throughout the machine's thermal cycle.

Specifications

Competitive Advantage

1. Exceptional Thermal Resilience for High-Heat Zones

Unlike standard proximity cables that are limited to lower temperatures, the 16925-12 is rated for operation up to +200°C. This superior thermal tolerance allows it to be installed in extreme environments, such as inside gas turbine housings or near steam-carrying components, without the risk of insulation failure or signal drift. This capability reduces the need for expensive heat shielding and extends the cable's service life in harsh thermal conditions.

2. Specialized 50 Ω Impedance Matching

The 16925-12 Sensor Proximity Probe Cable is engineered with a precise 50 Ω characteristic impedance to ensure perfect matching within legacy Bently Nevada transducer loops. This meticulous design prevents signal reflections and ensures the highest possible linearity across the transducer's full measurement range. This level of signal integrity is a significant advantage over generic cables, as it guarantees the accuracy of vibration data used for safety-critical machine trips.

3. Certified Safety for Global Industrial Standards

Equipped with both CSA and ATEX approvals, the 16925-12 provides a "universal" solution for hazardous area deployments worldwide. The factory-installed threaded connectors are designed to maintain a gas-tight seal and resist loosening under mechanical vibration. This certified safety profile eliminates compliance risks for plant managers and ensures that the monitoring system meets the highest international safety standards for explosive and volatile atmospheres.
