Product Overview

The Bently Nevada 40113-02 is a specialized environmental sealing kit engineered to safeguard the electrical connections between proximity probes and extension cables. In industrial vibration monitoring, the connection point—typically a miniature coaxial ClickLoc connector—is highly susceptible to contamination from oil, moisture, and corrosive chemicals. The 40113-02 kit provides a hermetic-like seal using high-grade silicone rubber, preventing signal attenuation and "ground loops" caused by fluid ingress. This protection is a fundamental requirement for maintaining the high-fidelity data transmission necessary for Turbine Supervisory Instrumentation (TSI) and predictive maintenance programs.

Industrial Applications and Operational Use Cases

The 40113-02 Connector Protector is an essential reliability component in any facility utilizing Bently Nevada eddy current transducers. Its use is critical in the following scenarios:

• Steam and Gas Turbines Protecting sensor connections from high-pressure steam leaks and pervasive oil mist within the bearing housings.

• Cooling Tower Monitoring Preventing water ingress and mineral buildup at the connector interface in high-humidity environments.

• Petrochemical Refineries Shielding sensitive electrical contacts from corrosive process gases and chemical vapors.

• Submerged Applications Essential for any sensor installation where the connector may be temporarily or permanently exposed to lubricating fluids.

• Preventing False Alarms By eliminating intermittent signal "noise" caused by connector oxidation or moisture, the 40113-02 reduces the risk of false machinery trips.

By ensuring the physical integrity of the signal path, the 40113-02 kit helps maintain the accuracy of the 4-20mA or dynamic voltage signals sent to 3500 series monitoring racks, effectively extending the calibration intervals and service life of the entire transducer system.
