This page covers the vibration monitoring hardware available from LOGGON TECH for condition-based maintenance on pumps, motors, fans, gearboxes and similar rotating machinery. The range includes wireless sensor nodes with integrated batteries, a gateway that collects data from up to 64 nodes, and a multi-channel instrument for remote-diagnosis work. The sensors measure triaxial vibration in the 10–5000 Hz band and are intended for continuous or periodic machine vibration monitoring in industrial plants.
Vibration monitoring: what this category covers and where it is used
A vibration monitoring system converts machine surface motion into a digital signal, either as an overall level (acceleration or velocity RMS), as a time waveform, or as a frequency spectrum. Overall levels are simple to trend against alarm thresholds; spectra separate individual frequency components so that bearing defect frequencies, gear mesh frequencies and running-speed harmonics can be identified. In practice most plants use both: overall levels for day-to-day alarms and spectra for diagnosis after an alarm is raised.
Typical applications for the products on this page include:
- Pumps and motors on process lines, where bearing degradation and misalignment are the common failure modes.
- Fans and blowers, where imbalance and looseness produce strong 1× running-speed components.
- Gearboxes, where gear mesh frequencies and their sidebands are the primary indicators.
- Assets in Ex-rated areas, since the LOGGON-401/401B sensors carry the published Exia IICT4Ga marking and the LOGGON-410 gateway a flameproof enclosure.
- Remote or hard-to-access equipment, where battery-powered wireless nodes avoid cable runs.
Which machines should be instrumented first is a reliability decision rather than a hardware decision. A common approach is to rank assets by consequence of failure and by failure history, then instrument the highest-ranked machines first and extend coverage as experience is gained.

The LOGGON-400 system consists of wireless sensor nodes and a gateway. Two sensor variants are available:
| Model | LOGGON-401 |
|---|---|
| Frequency range | 10–5000 Hz |
| Vibration range | ±16 g peak, triaxial |
| Temperature range | −40 to +125 °C |
| Protection | IP67 |
| Explosion-protection marking | Exia IICT4Ga (manufacturer-published) |
| Battery life | > 2 years |
| Model | LOGGON-401B |
|---|---|
| Vibration range | ±16 g, triaxial |
| Frequency range | 10–5000 Hz |
| Data provided | Acceleration, velocity, spectrum |
| Operating temperature | −40 to +85 °C |
| Explosion-protection marking | Exia IICT4Ga (manufacturer-published) |
| Power | Battery |
The LOGGON-410 gateway collects data from the nodes:
| Model | LOGGON-410 gateway |
|---|---|
| Node capacity | Up to 64 nodes |
| Enclosure | IP67, flameproof |
| Operating temperature | −20 to +60 °C |
| Supply | 100–265 V or 8–24 V |
LOGGON-V1 multi-channel instrument
The LOGGON-V1 is a multi-channel instrument supporting 64 nodes, with a typical data rate of 200 kbps and Ethernet connectivity plus optional 4G. It operates from −40 to +60 °C and can be powered from a rechargeable battery or mains supply. It is supplied with the standard wireless sensor LOGGON-401D:
| Sensor model | LOGGON-401D |
|---|---|
| Vibration range | ±16 g peak, triaxial |
| Frequency range | 10–5000 Hz |
| Data provided | Acceleration, velocity, spectrum |
| Temperature range (body) | −40 to +85 °C |
| Temperature range (sensor) | −40 to +125 °C |
| Power | Rechargeable battery |
The LOGGON-V1 configuration also includes remote expert diagnosis, so spectra recorded in the plant can be reviewed by specialists without a site visit.
How to select
Selection starts with the measurement task. If the requirement is periodic trending of overall levels on a large number of assets, the LOGGON-400 system with LOGGON-401 or LOGGON-401B nodes and a LOGGON-410 gateway is the simpler architecture. If spectra are needed continuously, or if remote diagnosis support is required, the LOGGON-V1 with LOGGON-401D sensors provides the documented 200 kbps transmission rate and the diagnosis service.
- Check the temperature at the mounting point against the sensor rating. The LOGGON-401 and the LOGGON-401D sensor element reach +125 °C; the LOGGON-401B and the LOGGON-401D body are rated to +85 °C.
- Confirm the hazardous area classification. The LOGGON-401 and LOGGON-401B sensors carry the manufacturer-published Exia IICT4Ga marking; the LOGGON-410 gateway uses a flameproof IP67 enclosure.
- Count the nodes per gateway or instrument. Both the LOGGON-410 and the LOGGON-V1 support up to 64 nodes.
- Decide on power. The LOGGON-410 accepts 100–265 V or 8–24 V; the LOGGON-V1 runs from mains or its rechargeable battery.
- Set alarm thresholds from baseline data recorded on the machine in good condition, and review them after the first months of operation.
Integration and communication
The LOGGON-410 gateway aggregates node data; its uplink interface is confirmed per project. The LOGGON-V1 provides Ethernet as standard and optional 4G, which allows a machine vibration monitoring installation to report to a remote server without a dedicated plant network connection. Plan the physical layout so that nodes remain within radio range of the gateway or instrument; the IP67 and flameproof enclosure ratings of the gateway allow it to be mounted in the production area rather than in a control room. Where data is exported to a CMMS or historian, agree the tag naming and sampling interval with the maintenance team before commissioning.
FAQ
Do I need spectra or are overall levels sufficient?
Overall levels are sufficient for alarm generation on many machines, but they do not identify the cause of a change. Spectra allow bearing, gear and imbalance problems to be separated. The LOGGON-401B and LOGGON-401D provide acceleration, velocity and spectrum data.
How many sensors can one gateway handle?
The LOGGON-410 gateway supports up to 64 nodes. The LOGGON-V1 instrument also supports 64 nodes.
Can the sensors be used in hazardous areas?
The LOGGON-401 and LOGGON-401B sensors carry the manufacturer-published Exia IICT4Ga marking. The LOGGON-410 gateway is housed in an IP67 flameproof enclosure. Verify the classification of your specific area against these ratings before installation.
What battery life should I expect?
The LOGGON-401 is specified with a battery life of more than 2 years. Battery life depends on sampling interval and radio conditions, so confirm the expected figure for your configuration with the manufacturer.
