3300 XL 11 mm Proximity Transducer System Introduction

Transducer System

The 3300 XL 11 mm Proximity Transducer System consists of:

1.3300 XL 11 mm probe

2. 3300 XL 11 mm extension cable

3. 3300 XL 11 mm Proximitor Sensor

The 3300 XL 11 mm Proximity Transducer System has a 3.94 V/mm (100 mV/mil) output for non-contacting vibration and displacement measurements on fluid film bearing machines. The large 11 mm tip enables this transducer system to have a longer linear range compared to our standard 3300 XL 8 mm Transducer System. It is primarily used in the following applications where the longer linear range is necessary:

1. Axial (thrust) position measurements

2. Ramp differential expansion measurements on steam turbines

3. Rod position or rod drop measurements on reciprocating compressors

4. Tachometer and zero speed measurements

5. Phase reference (Keyphasor) signals

The 3300 XL 11 mm Proximitor Sensor is designed to replace the 7200-series 11 mm and 14 mm Transducer Systems. When upgrading from the 7200-series system to the 3300 XL 11 mm system, every component must be replaced with 3300 XL 11 mm components. In addition, the monitoring system must be updated. If using a 3500 Monitoring System, an updated version of the configuration software that lists the 3300 XL 11 mm Transducer System as a compatible option is required. Existing 3300 Monitoring Systems may need a modification.

Proximity Probe and Extension Cable

The 3300 XL 11 mm probe comes in varyingprobe case configurations, including armored and unarmored ½-20, 5⁄8 -18, M14 X 1.5 and M16 X 1.5 probe threads. The reverse mount 3300 XL 11 mm probe comes standard with either 3⁄8-24 or M10 X 1 threads. All components of the transducer system have gold-plated brass ClickLoc connectors. ClickLoc connectors lock into place, preventing the connection from becoming loose. The patented TipLoc molding method provides a robust bond between the probe tip and the probe body. The probe cable is securely attached to the probe tip utilizing our patented CableLoc design that provides 330 N (75 lb) pull strength.

3300 XL Probes and Extension Cables can also be ordered with a FluidLoc cable option. This option prevents oil and other liquids from leaking out of the machine through the cable’s interior. The connector protector option provides additional protection of the connectors in a humid or moist environment. Connector protectors are recommended for all installations and provide increased environmental protection2. Additionally, the 3300 XL 11 mm probe comes standard with a locknut with pre-drilled safety wire holes.
