The 330380-90-00 is a 3300 XL 16mm Temperature-rated Proximitor Sensor that functions within industrial vibration monitoring networks. This specific 330380-90-00 model operates with a total system cable length of 9 meters, which accommodates installation routing configurations across large-scale rotating machinery setups requiring extended cable range.
Threaded and smooth case styles for various types of probe mounting
Ceramic tip and stainless steel construction resists heat, moisture and corrosion
Hardline cable available in lengths of 1, 2 and 5 metres for routing cable through hot sections of the machine
The 3300 High Temperature Proximity System (HTPS) is designed to withstand the extreme temperatures found inside gas turbines, steam turbines and other types of rotating machinery. The 330380-90-00 functions as a temperature-rated proximity component to perform displacement measurement within thermal industrial environments where standard proximity sensors do not maintain operation.
In terms of application scenarios, the 330380-90-00 monitors shaft vibration and position variations within the temperature zones near steam turbine casings to output displacement data. It also monitors compressor thrust bearing positions to track proximity metrics in turbomachinery protection systems, and serves in gas expander and boiler feed pump frameworks subject to thermal environments.
Through these applications, the 330380-90-00 supplies data for rotor dynamics assessment and machinery health diagnostics across petrochemical processing, power generation, and heavy industrial facilities that require thermal management and machinery protection capabilities.

The operation of the 330380-90-00 requires strict compliance with mechanical installation, electrical routing, and thermal environment protection specifications. Mechanically, the proximitor must be securely fixed to control panels or enclosures using its panel-mount configuration, maintaining proper electrical isolation between the housing and the grounding rail.
Electrically, its 9-meter total system cable length imposes strict impedance requirements, meaning field cutting or splicing of the cable is strictly prohibited, and the bend radius must remain within specified limits to prevent signal distortion.
Lastly, although this component is temperature-rated, technicians must periodically clear dust and localized moisture from the terminal blocks and check the tightness of the miniature coaxial connectors to prevent signal fluctuations caused by a drop in insulation resistance.
The Bently Nevada 330380-90-00 is a 3300 XL series 16mm industrial temperature-rated proximitor sensor that employs a panel-mount structure and a standard configuration requiring no agency approval, featuring a 9-meter total system cable length. This component performs displacement measurement based on non-contact eddy current principles and functions in thermal industrial environments where standard sensors do not operate, serving in shaft vibration and axial position monitoring for steam turbines, compressors, gas expanders, and boiler feed pumps to supply data for machinery protection across power generation and petrochemical sectors.
