INSTALLATION
Side-exit configuration
The 04 case option uses a smooth 1.06 in diameter body with a side cable exit, making the configuration suitable for installation arrangements where cable routing behind the probe is restricted. SST ARMOR
The 01 armor option adds stainless-steel protection to the probe cable assembly. |

3300 XL 25 mm SYSTEM ARCHITECTURE
The probe is one part of a matched transducer chain
For a replacement installation, the probe, extension cable and Proximitor Sensor configuration should be treated as a complete transducer system. The 3300 XL 25 mm architecture was designed to provide compatibility across the probe, extension and Proximitor components.

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.
3500/22M is a Transient Data Interface Module manufactured and designed by Bently Nevada as part of the 3500 Series used for monitoring seismic activity. The 3500/22M 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.
