7200
PROXIMITY FAMILY The 7200 family includes different probe constructions and mounting configurations so that probe diameter, mounting style, cable arrangement and installation geometry can be matched to the machinery location.
|
|
|
Rotating Equipment
The proximity measurement principle is suited to machinery where shaft movement must be observed without physical contact. Typical monitoring applications include radial vibration and shaft-position measurements on rotating machinery.
|
Machinery Protection
When connected to the appropriate 7200-series electronics and monitoring chain, the probe provides the physical sensing element required to convert changes in probe-to-target gap into an electrical measurement used for machinery condition assessment.
|
|
Installation-Related Risk
Incorrect probe positioning, unsuitable mechanical clearance, damaged cable routing or an inappropriate mounting configuration can produce unstable or misleading measurements. The probe should therefore be installed with correct mechanical alignment and gap.
|
Signal-Chain Risk
A healthy probe alone does not guarantee a valid monitoring channel. Probe, cable, Proximitor electronics and monitor settings must be compatible. Cable or connector damage should be considered when a channel develops intermittent or abnormal behavior.

|
01
8 mm Sensing Tip
The larger 8 mm probe platform is intended for the standard 7200 mounting arrangement.
|
02
Standard Mount
The 3/8-24 configuration supports conventional English-thread installation requirements.
|
03
Integrated Cable
The selected code provides a 1.0 m cable length as part of the probe configuration.
|
04
Mini Coax Connection
The final code position specifies a miniature male coaxial connector.
|
| 01 |
Why should I verify the 21504-00-48-10-02 case length before replacing an installed probe?
Because the “48” configuration corresponds to a 4.8-inch overall case length. Matching the existing mechanical geometry helps prevent a replacement probe from interfering with surrounding hardware or sitting at an unsuitable sensing position.
|
| 02 |
Is the 21504-00-48-10-02 a suitable choice when the machine already uses a 3/8-24 standard probe mounting arrangement?
Yes, the 21504 family is the 8 mm standard-mount configuration using 3/8-24 threads. The existing installation should still be checked for the required case length, cable arrangement, connector and sensing geometry before ordering.
|
| 03 |
What does the 10 in 21504-00-48-10-02 mean for maintenance planning?
The “10” identifies the 1.0 m cable configuration. This is important when replacing a probe because cable reach and routing can affect whether the replacement can be installed without changing the established field wiring arrangement.
|
| 04 |
Does the 21504-00-48-10-02 include a connector that should be checked against the existing signal chain?
Yes. The “02” configuration specifies a miniature male coaxial connector. The mating connection and associated 7200-series electronics should be verified before purchasing, particularly when replacing an older probe with a different connector arrangement.
|
| 05 |
What should I compare first when replacing a 21504-00-48-10-02 with another 7200-series probe?
Compare the probe diameter, mounting thread, unthreaded length, overall case length, cable length, connector and lead-armoring configuration. Two probes from the same family are not automatically mechanically interchangeable simply because their base model is similar.

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 3500/33 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.
