Description
The 21747-045-00 Proximeter Extension Cable is a specialized high-performance signal transmission component within the Bently Nevada transducer ecosystem. Specifically engineered for the 7200 and 3300 series proximity systems, the 21747-045-00 Proximeter Extension Cable acts as the critical bridge between the proximity probe and the Proximitor sensor. In modern industrial monitoring, the 21747-045-00 Proximeter Extension Cable is essential for maintaining the fidelity of eddy current signals, ensuring that the voltage output remains accurately proportional to the gap between the probe tip and the target conductive surface. This 4.5-foot (approximately 1.37 meters) cable is designed to provide the necessary reach for complex machinery installations while strictly adhering to the electrical impedance requirements of the monitoring system.
As a core part of the Proximeter Extension Cable category, the 21747-045-00 is built to withstand the rigors of heavy industrial environments. It features a miniature coaxial ClickLoc connector paired with a connector protector, which prevents accidental disconnection and shields the junction from moisture and contaminants. This 21747-045-00 Proximeter Extension Cable is fully compliant with CE (EMC) standards and is RoHS compliant, reflecting its high manufacturing quality and environmental safety. The cable's triaxial construction and specialized shielding effectively mitigate electromagnetic interference (EMI), which is vital for preserving the system's 2 mm linear range and preventing data corruption in electrically noisy areas like turbine halls or pump stations.
Applications
The 21747-045-00 Proximeter Extension Cable is primarily utilized in power generation and petrochemical facilities to link proximity probes with Proximitor sensors on large-scale rotating equipment. Its 0.5-meter (1.6 feet) length is specifically suited for compact installations where the sensor is mounted in a nearby junction box or on the machine casing itself. It provides a low-noise path for radial vibration and axial position signals, which is critical for the continuous monitoring of steam turbines, generators, and high-speed centrifugal compressors.
In environments where space is highly constrained, such as within the internal housings of pumps or small motor assemblies, the 21747-045-00 provides the necessary flexibility for signal routing. The miniature coaxial ClickLoc connector with a protector ensures a secure, vibration-resistant link that can be threaded through tight conduits. This makes it an ideal choice for machinery where the gap between the measurement point and the electronics is minimal but requires a high degree of signal integrity and mechanical durability.
This Proximeter Extension Cable is also a key component in Keyphasor and speed measurement setups across various manufacturing sectors, including steel and paper mills. Because it supports a wide operating temperature range from -45°C to +150°C, the 21747-045-00 can be safely deployed near hot bearing caps or in frigid outdoor settings. Its ability to maintain stable capacitance ensures that timing pulses for phase analysis remain sharp and accurate, facilitating precise balancing and diagnostic routines for critical production line assets.

Competitive Advantage
Enhanced Signal Integrity with ClickLoc Technology: The 21747-045-00 is equipped with a miniature coaxial ClickLoc connector system. This design provides a positive "lock" that prevents signal loss caused by mechanical vibration—a common failure point in standard threaded cables. The included connector protector further shields the interface from oil and moisture, ensuring that the Proximeter Extension Cable delivers consistent data even in the most demanding "wet" industrial environments.
Superior Thermal and Environmental Resilience: With an operational threshold spanning from -45°C to +150°C, this extension cable outperforms generic alternatives by maintaining its electrical properties under extreme thermal stress. The triaxial shielding and high-grade insulation materials prevent signal drift and insulation breakdown, allowing the 21747-045-00 Proximeter Extension Cable to be used in high-heat turbine zones without the risk of false alarms or system failure.
Optimized Electrical Stability and Compliance: The cable is precision-engineered to meet a typical capacitance of 68.5 pF/m, which is vital for maintaining the linearity of the entire transducer system. Being CE (EMC) and RoHS compliant, the 21747-045-00 guarantees that it will not introduce or be affected by electromagnetic interference in dense industrial wiring environments. This high level of electrical consistency ensures "plug-and-play" interchangeability, eliminating the need for time-consuming field calibrations.
