Description

330850-91-05: 3300 XL 25 mm Proximitor Sensor configured for a 9.0-metre system length with integrated DIN-mount support (Option 91) and multiple hazardous area agency approvals (Option 05).

This Proximitor sensor is calibrated to pair with a 3300 XL 25 mm proximity probe and a matching extension cable to form a complete 9.0-metre transducer system. Compared to panel-mount configurations or shorter 5.0-metre systems, this model features a pre-installed DIN-mount pad that allows secure installation onto standard 35 mm DIN rails, simplifying industrial enclosure layouts. It is calibrated by default for AISI 4140 steel targets, serving large-target eddy-current displacement measurements such as steam turbine thrust position and differential expansion.

Features

Option 91 provides 9.0-metre total system length calibration, matching the combined electrical length of the probe and extension cable.
DIN-mount mounting pad (Option 91) facilitates rapid installation onto standard 35 mm DIN rails.
Option 05 Multiple Approvals package offers certified protection for installation in Class I Division 1/2 and Zone 0/1/2 hazardous areas.
SpringLoc terminal strips provide reliable, tool-free terminal wiring, securing 0.2 to 1.5 mm2 (16 to 24 AWG) field cables.
Active RF shield design minimizes interference from nearby high-frequency radio signals, preserving sensor accuracy.

Applications

Steam turbine thrust position monitoring
Differential expansion measurement on high-capacity rotating machinery
Large shaft target axial displacement tracking
Rod-drop monitoring in reciprocating compressors

Installation Guidelines

Mount securely on standard 35 mm DIN rail inside an IP54 or better protective enclosure.
Ensure a minimum clearance of 3.05 mm (0.120 in) is maintained for DIN rail insertion and removal.
Avoid routing field wiring parallel to high-voltage power cables to mitigate electromagnetic interference.
Apply self-fusing silicone tape or connector protectors over coaxial connections to prevent moisture contamination.
Connect the field wiring shield exclusively at the monitor end to eliminate potential ground loop issues.
