Датчик приближения Bently Nevada 330850-50-00 3300 XL 25 мм

Description

330850-50-00 specifies a 3300 XL 25 mm Proximitor Sensor configured with a 5.0-metre system length, flat-surface panel mounting, and no agency approvals. This sensor functions as an analog signal conditioner within a 3300 XL 25 mm Proximity Transducer System, generating a continuous voltage output directly proportional to the distance between a paired 25 mm probe tip and a target material.

Unlike DIN-mount configurations or variants built with intrinsic safety approvals, this unit is designed specifically for general-purpose, non-hazardous area panels. It supports large-target displacement monitoring applications, such as steam turbine thrust position and differential expansion. The system is designed to provide stable performance over extended temperature ranges when paired with 330851 probes and 330854 extension cables.

Features

• System length of 5.0 metres (Option 50) is matched for calibration with standard five-meter probe and cable assemblies.
• Panel-mount mounting style (Option 50) comes complete with four 6-32 thread-forming mounting screws.
• No agency approvals (Option 00) simplifies installation in standard general-purpose plant areas.
• SpringLoc terminal strips provide reliable, direct field wiring connections without requiring specialized crimping or landing tools.
• A380 aluminum housing is constructed to resist environmental corrosion and shield inner circuitry from electromagnetic noise.
• Active voltage regulation maintains high stability with less than 2 mV output drift per volt of supply input fluctuation.

Applications

• Steam turbine thrust position monitoring
• Differential expansion measurements on large utility turbine shafts
• Reciprocating compressor rod-drop and displacement tracking
• Large-diameter rotor mechanical position and vibration analysis

Installation Guidelines

Mount the Proximitor on a flat metal panel or enclosure surface using the four supplied 6-32 thread-forming panel screws. Strip external field wire insulation to reveal conductors from 0.2 to 1.5 mm2 (16 to 24 AWG) and insert directly into the SpringLoc terminal blocks. Thread coaxial connections finger-tight to ensure robust contact, not exceeding the maximum recommended torque limit of 0.565 Nm (5 in-lb). Maintain environmental conditions within the operating temperature limits and protect coaxial connectors with self-fusing silicone tape if moisture exposure is possible.
