3300 XL Proximity Transducer System Introduction

The 3300 XL 25 mm Proximitor Sensor has the same advanced features as our previous 3300 XL Proximitor Sensors.  Its thin design allows it to be mounted in either a high-density DIN-rail installation or a more traditional panel mount configuration. Improved RFI/EMI immunity allows the 3300 XL Proximitor Sensor to achieve European CE mark approvals without any special mounting considerations.  This RFI immunity also prevents the transducer system from being adversely affected by nearby high frequency radio signals.  SpringLoc terminal strips on the Proximitor Sensor require no special installation tools and facilitate faster, highly robust field wiring connections.

The correct operation of the transducer system must be verified during installation, and periodically after installation, by physically moving it to simulate the motion of the shaft collar.  This requires a mounting bracket that allows the transducer system to slide relative to the shaft rotor and collar. An optional 3300 XL Sliding Bracket can be ordered for the 25 mm Differential Expansion Transducer for both single transducer and complementary input applications.  This mounting bracket makes it easy to accurately verify the transducer system and gap the probes by allowing you to slide the transducer system throughout its linear range.  The base plate of the sliding bracket is installed on the inner surface of the turbine case near the differential expansion collar.  Probes are installed in the applicable probe adapter, which attaches to the sliding carriage. The sliding carriage slides onto and is secured to the base plate with bolts and safety wire.  To verify and install the transducer, loosen thebolts securing the sliding carriage to the base plate and move the sliding carriage and probes.  A Dial Indicator Verification Kit accessory provides a reference by measuring the movement of the sliding carriage.  The 3300 XL Sliding Bracket helps ensure that the transducer system remains aligned with and perpendicular to the rotor.
