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).

Description
The Bently Nevada 330876-02-90-00-00 is a 3300 XL 50 mm Proximity Probe specifically engineered as a high-temperature proximity sensor for extreme industrial monitoring applications. As an integral component of the 3300 XL proximity transducer system, the 330876-02-90-00-00 delivers continuous, accurate measurement capabilities specifically designed to survive the harshest steam turbine Direct Environment (DE) conditions where thermal stress and moisture ingress compromise standard sensing equipment.

This 330876-02-90-00-00 proximity probe is specifically designed to solve critical measurement challenges in high-temperature rotating machinery environments. The 330876-02-90-00-00 maintains its accuracy while continually operating in continuous high temperatures up to 200°C (392°F), and can withstand intermittent high temperatures up to 250°C (482°F). The probe solves moisture penetration issues through both a front and rear seal architecture, which—combined with the standard High Temperature FluidLoc cable—prevents moisture from entering the probe tip. Additionally, the 330876-02-90-00-00 incorporates special high-temperature ClickLoc connectors as standard equipment on both the probe and extension cable, accompanied by connector protectors and a disposable connector protector installation tool to ensure the connections remain free of contamination. The ClickLoc connector on the probe lead features a removable collar that facilitates routing the cable through tight clearances.

The 330876-02-90-00-00 features a Probe Case Type with M14x1.5 Thread and a Total Length of 9.0 meters (29.5 feet). The Armor Option utilizes High Temperature FluidLoc Cable as the standard configuration across all 50 mm probes. The 330876-02-90-00-00 carries No Agency Approvals. For mechanical mounting, this straight exit probe includes a locknut with predrilled safety wire holes, and the overall case diameter measures 1.99 inches.

The 330876-02-90-00-00 is primarily applied in steam turbine DE (Direct Environment) monitoring systems, where extreme thermal exposure and potential moisture contamination present significant operational challenges to measurement reliability. This 330876-02-90-00-00 serves essential protection and monitoring functions in high-temperature industrial rotating machinery, including steam turbine shaft vibration monitoring, position measurement, and machinery protection systems requiring thermal resilience up to 200°C continuous operation. The probe addresses critical needs in power generation and heavy industrial environments where steam turbine integrity depends on accurate, continuous proximity sensing under thermal duress.
