The 3300 5 mm transducer system is intended for noncontacting measurements where direct observation of shaft motion is required. Bently Nevada identifies vibration and position measurement on fluid-film bearing machines as primary applications.
Provides noncontacting dynamic vibration measurement of rotating shafts.
Supports static position measurement within machinery monitoring systems.
The 3300 5 mm system can be used for Keyphasor measurement applications.
Suitable for specified speed and tachometer measurement applications.
When a proximity probe signal becomes unavailable, unstable or inconsistent with the expected machine condition, the probe and associated transducer chain can become an important inspection point. Loss of reliable shaft vibration or position information can reduce the ability of the monitoring system to identify developing machinery conditions and may increase the operational risk of critical rotating equipment.
Eddy-current proximity technology measures the distance between the probe tip and a conductive target without physical contact.
The 3300 XL probe, extension cable and Proximitor sensor are designed as an interchangeable transducer system.
Gold-plated ClickLoc connectors use a locking mechanism designed to prevent loosening and require no special installation tools.
Our team focuses on hard-to-find automation and machinery-monitoring components, helping maintenance teams identify the required part quickly and arrange efficient international delivery.
The 3300 5 mm transducer system supports noncontacting static position and dynamic vibration measurements, with applications also including Keyphasor and speed measurement.
Bently Nevada identifies the smaller 5 mm physical package as useful where physical mounting constraints prevent the use of an 8 mm probe, such as restricted spaces around thrust-bearing pads.
The specified recommended gap setting is 1.27 mm (50 mils), with a linear range extending approximately from 0.25 to 2.3 mm.
The official ordering structure identifies option 02 as a miniature coaxial ClickLoc connector with standard cable.
The factory calibration default for the Proximitor Sensor is AISI 4140 steel. Calibration for other target materials is available as specified by the manufacturer.
Check the complete transducer chain, including probe installation, connector condition, extension cable and Proximitor sensor, before treating the signal as a machinery-condition change.

The 3500/22M 138607-01 Transient Data Interface (TDI) is the interface between the 3500 monitoring system and compatible software (System 1 Condition Monitoring and Diagnostic software and 3500 System Configuration software). The TDI combines the function of a 3500/20 Rack Interface Module (RIM) with the data collection capability of a communication processor such as TDXnet.

The 3500/33 16-Channel Relay Module is a full-height module that provides 16 relay outputs. You can place any number of 16-channel relay modules in any of the slots to the right of the Transient Data Interface (TDI) Module. Each output of the 3500/33 16-Channel Relay Module can be independently programmed to perform voting logic.
The 3500/60 & 61 modules provide six channels of temperature monitoring and accept both Resistance Temperature Detector (RTD) and Thermocouple (TC) temperature inputs. The modules condition these inputs and compare them against user-programmable alarm setpoints. The 3500/60 and 3500/61 provide identical functionality except that the 3500/61 provides recorder outputs for each of its six channels while the 3500/60 does not.

The 3500/72M Recip Rod Position Monitor meets API 618 requirements for reciprocating compressors. It measures: l Rod position l Rod drop l Hyper-compressor The four-channel 3500/72M Recip Rod Position Monitor accepts input from proximity transducers, conditions the signal to provide dynamic and static position measurements, and compares the conditioned signals with userprogrammable alarms. Each channel, depending on how you configure it, typically conditions its input signal to generate various parameters called measured values.
The 3500/62 Process Variable Monitor is a 6-channel monitor for processing machine critical parameters that merit continuous monitoring, such as pressures, flows, temperatures, and levels. The monitor accepts +4 to +20 mA current inputs or any proportional voltage inputs between -10 Vdc and +10 Vdc. It conditions these signals and compares the conditioned signals to user-programmable alarm setpoints.
