Linesense

Linesense Health

Know which machine is about to fail before it stops the line. Linesense Health watches vibration and temperature on motors, pumps, fans and gearboxes, and raises an alarm while there is still time to plan the repair.

Failures start long before the stop

A bearing doesn't fail in a moment. It gets worse in stages, and the first stage is visible in the vibration long before anyone can hear or feel it. Linesense looks for that first stage.

Early vibration change

Wear and looseness change the vibration pattern. Your ears and hands can't tell yet. A sensor can.

Noise and heat

Now the machine sounds rough or runs hot. A good technician notices, but the repair is already urgent.

Breakdown

The machine stops, often mid-shift, often with collateral damage. Spares and people are found in a hurry.

Illustration of a typical pattern, not a measurement. How early the first alert comes depends on the fault, the machine and its load. A pilot shows it on your own machines.

Alarms that follow an international standard

Overall vibration is graded into the four zones of ISO 20816. Everyone in maintenance can read a zone, and an auditor recognises it.

Pump 3 bearing, example
Lower vibrationHigher vibration
Zone A

A new machine. Vibration of newly commissioned equipment normally falls here.

Zone B

Acceptable. The machine can run for long periods without restriction.

Zone C

Act soon. Not fit for long-term running. Plan the repair at the next convenient stop.

Zone D

Damage is likely. Vibration is severe enough to harm the machine.

The limits between zones depend on machine class: size, speed and how the machine is mounted. A large pump and a small fan have different limits. You set the class for each machine and Linesense applies the matching limits.

Two sensor grades, and what each one catches

Not every motor needs the same sensor. Use the simple one widely, and the detailed one where a failure would hurt most.

Alarm grade

Measures overall vibration and temperature, and grades them against the ISO zones. It answers one question: is this machine getting worse?

  • Imbalance, for example a fouled fan blade
  • Looseness, such as a slack foot bolt
  • Misalignment between motor and pump
  • Overheating of the bearing or motor
Best for
Many motors, fans and pumps at a low cost per point
Tier
Health Watch and up

Diagnostic grade

Also records the frequency spectrum. Each fault has its own signature, so it can say what is wrong, not only that something is.

  • Bearing faults at an early stage
  • Gear tooth wear and damage
  • Everything alarm grade finds, with the cause named
  • Fault indicators for imbalance, misalignment and bearing wear
Best for
Critical assets: large motors, gearboxes, compressors, main fans

From a reading to a repair

An alarm only matters if someone acts on it. Health carries each alert through to the job.

A health score for every asset

Vibration, temperature and their trend combine into one status per machine. Open the list and the machines that need attention are at the top.

Trends over days and months

See how each machine has behaved against its zone limits, and watch a slow rise long before it crosses into zone C.

Baselines and anomaly alerts

Linesense learns what normal looks like for each machine at its own speed and load, then alerts when it drifts, even before a zone limit is reached. Health Pro.

Spectrum view

Look at the frequency spectrum behind an alarm, with fault indicators for imbalance, misalignment and bearing wear. Your analyst, or ours, can confirm the diagnosis. Health Pro.

Work orders

Turn an alarm into a work order with the machine, the reading and the trend attached, and track it until it is closed. Health Pro.

SAP PM notifications

On Enterprise, Linesense creates the maintenance notification in SAP PM for you, and can feed other maintenance systems as well.

Where the sensor goes decides what it sees

A sensor on the wrong spot misses the fault. These rules apply to every machine we install on.

On the bearing
On the bearing housing, as close to the bearing as you can get. Not on the fan cover or the sheet-metal guard.
On bare metal
Fixed to clean, bare metal with a stud or epoxy pad. Magnets are for surveys only, not for permanent monitoring.
In the load direction
Aimed along the direction the machine pushes on its bearing, usually radial and often vertical.
Both ends
On a critical motor, one point at the drive end and one at the non-drive end. A pump gets one on its own bearing housing.

Three tiers, one platform

Priced per monitored point, which is one sensor on one bearing. We quote after we know your machines.

Questions maintenance teams ask

Do I need Linesense OEE to use Health?

No. Health works on its own. Running both on the same machines adds the link from a stop to the alarm that preceded it, and one login for production and maintenance.

How much warning will I get?

It depends on the fault, the machine and its load, so we don't promise a fixed number of weeks. Bearing faults on diagnostic-grade sensors tend to show earliest. A pilot shows what you get on your own machines.

Which machines can it monitor?

Rotating equipment with bearings: motors, pumps, fans, compressors and gearboxes. Very slow machines and non-rotating equipment need a different approach, and we tell you so on the survey.

Which sensor grade should I start with?

Alarm grade on the many ordinary motors, fans and pumps, and diagnostic grade on the few machines that would hurt most if they failed. You can mix both on one site.

What happens when the internet drops?

The edge device keeps recording at the plant and sends the readings when the link returns. Connections are outbound only, so nothing opens on your firewall.
