Condition monitoring with Vexron

Online vibration monitoring system for Indian plants

Continuous vibration monitoring for motors, pumps, fans and gearboxes. Vexron works with the sensors and PLC data you already have, or sensors you add, and runs on an edge gateway inside your plant.

What is an online vibration monitoring system?

An online vibration monitoring system measures machine vibration all the time, instead of once a month with a handheld meter. Sensors on the bearings feed an edge device. Software compares each reading with ISO zones and the machine's own normal pattern, and your team gets an alert when a fault starts to develop.

The system

What a vibration monitoring system includes

Four parts, from the bearing to the person who fixes it. Vexron is the edge gateway, the software and the alerts. It reads the sensors; we do not make them.

  1. 01

    Sensors

    Vibration sensors on bearing housings, plus temperature and motor current where available. Use the ones you have and add more only on critical machines.

  2. 02

    Edge gateway

    Collects data from sensors, PLCs and SCADA over Modbus, Siemens S7, OPC-UA or EtherNet/IP. Works out vibration metrics on site and stores 100,000+ readings if the network drops.

  3. 03

    Software and models

    Compares each reading with ISO 10816 / ISO 20816 zones and with the machine's own normal pattern. VMI-1 names the likely fault.

  4. 04

    Alerts and actions

    Alerts ranked by severity, sent by SMS or WhatsApp or passed to SAP S/4HANA, your MES or MQTT, so a warning becomes a job.

Machines

Which machines it monitors

Electric motors

Bearing wear, imbalance and looseness, read from vibration together with bearing temperature and motor current.

Pumps

Bearing wear and misalignment on process and utility pumps, where a failure stops a line.

Fans and blowers

ID, FD, cooler and bag-house fans. Imbalance and bearing faults show up early as a change in the vibration signature.

Gearboxes and drivetrains

Gear-mesh and bearing defects in critical drivetrains, caught before they damage the rest of the gearbox.

Compressors and chillers

Vibration trends plus power draw, so idle running is counted in rupees as well as flagged.

Kiln drives and mills

Motors, gearboxes and pinion bearings on kiln and mill drives. Slow-turning kiln parts need temperature and power trends instead.

Fault detection runs on our VMI-1 model, which separates bearing, alignment, imbalance and looseness signatures instead of raising one generic alarm. For a cement line, see what to monitor on the kiln, mills and fans.

Alerts

Alerts based on ISO zones and each machine's baseline

ISO 10816, now largely replaced by ISO 20816, sorts a vibration reading into four zones. The limits depend on machine size and how it is mounted, so one site-wide threshold is almost always wrong.

Vexron alerts on both: the ISO zone, and a change from the machine's own normal pattern. A machine can sit in zone B and still be getting worse week by week.

  • Zone A

    Good

    Typical of a newly commissioned machine.

  • Zone B

    Acceptable

    Fine for long-term running.

  • Zone C

    Plan a repair

    Not acceptable for long-term running. Schedule the work.

  • Zone D

    Act now

    Severe enough to cause damage to the machine.

Monitoring, not protection. Vexron watches machines and predicts faults. It is not an API 670 machinery protection system, so keep your existing protection relays and trip circuits in place.

Online or route-based?

Do you need continuous monitoring at all?

Not on every machine. Handheld route readings are cheap to start and fine for machines where a failure is not costly. Their weakness is the gap between rounds: a fault that develops quickly can go from fine to failed before the next walk.

Continuous online monitoring pays off on critical machines, where one failure between rounds is expensive. Most plants use both.

A fair, side-by-side look at both approaches, including when route-based checks are the better choice.

Getting started

How a rollout works

01

Pick the critical machines

List the machines whose stop costs you the most. Start with a handful, not the whole plant.

02

Short assessment

We check what data you already have (PLC tags, SCADA, sensors) and what needs adding.

03

Install and learn

The edge gateway goes in and VMI-1 learns each machine's normal running pattern.

04

Alerts, review, expand

Your team gets alerts, checks them against the baseline, and adds machines once they prove useful.

What it costs

There is no fixed list price. The cost depends on how many machines you monitor, the data you already have and the sensors you need to add. We quote per plant configuration after a short assessment. To size the problem first, put a rupee figure on one hour of downtime.

FAQ

Common questions

About vibration monitoring with Vexron. More on the Vexron product page.

Yes, where the data can be reached. Vexron reads sensors wired into your PLCs or SCADA, and devices that speak Modbus, Siemens S7, OPC-UA or EtherNet/IP. Where a critical machine has no sensor, one can be added through the Vexron platform.
