Features:
- Proximity Measurement Interface for Harsh Steam Turbine DE Environments
- Integrates High-Temperature FluidLoc Cable with Dual-Seal Moisture Protection
- Functions Within the 3300 XL 50 mm Proximity Transducer System and Compatible Monitors
The 330876-02-90-00-00 operates as the 3300 XL 50 mm Proximity Probe in a 3300 XL proximity transducer system, providing reliable displacement measurement to all compatible monitors within the system. It continuously operates and maintains its accuracy in high temperatures up to 200°C (392°F), and can withstand intermittent high temperatures up to 250°C (482°F). The probe features a total length of 9.0 meters (29.5 feet) with a straight exit M14x1.5 metric thread case style, an overall case diameter of 1.99 inches, High Temperature FluidLoc cable armor as standard, and carries no agency approvals. Seamless moisture protection is provided by the 330876-02-90-00-00 through both a front and rear seal which, combined with the High Temperature FluidLoc cable, prevent moisture from entering the probe tip. Special high-temperature ClickLoc connectors are also standard on the 330876-02-90-00-00, featuring a removable collar that facilitates routing the cable through tight clearances, and each probe comes with connector protectors and a disposable connector protector installation tool to ensure that the connectors remain free of contamination.
The 330876-02-90-00-00 provides essential sensing functions common to the entire transducer system, and is a critical component of the monitoring path, directly affecting the proper, normal operation of the overall machinery protection system. One 330876-02-90-00-00 probe is required per measurement channel depending on the desired monitoring point.
FFor complete transducer system applications, the 3300 XL 50 mm system requires a compatible extension cable and proximity monitor connected to the 330876-02-90-00-00 probe. In addition to standard single probe operation, the complete configuration also performs continuous position and vibration monitoring. The 3300 XL transducer system executes measurement using the internal circuitry specified in the probe options. Using this method, the monitoring system continually tracks the position and vibration of the rotating machinery. If the system detects that shaft displacement exceeds configured tolerance levels, it will automatically generate an alarm and place an event in the System Event List.
The 330876-02-90-00-00 Bently Nevada 3300 XL 50 mm Proximity Probe may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
