Fluke 802EN Vibration Meter

802EN Vibration Meter – One-Button Machine Vibration Screening

Know Which Machines Need Attention Before They Stop the Line

Most rotating equipment gives plenty of warning before it fails. A bearing wears, a coupling drifts, a mount works loose, and vibration climbs well before anyone hears a problem. The trouble is that many maintenance teams have no fast way to check for it. Full vibration analysis takes specialist gear and a trained analyst, and neither can get around every pump and fan on the site each week. So the walkaround often comes down to a hand on the housing and an experienced ear.

That method depends on who’s on shift, and it leaves nothing to compare next month.

The Fluke 802EN vibration meter fills that gap. It’s a handheld screening tool for overall machine vibration, built for the technician doing the rounds rather than the reliability specialist back at the desk. You get a number you can record, repeat and act on, and you can use it to decide whether a machine keeps running, goes on the watch list or gets booked in for further diagnosis.

What the Fluke 802EN Does

The 802EN pairs a built-in piezoelectric accelerometer with a very simple operating routine. Fluke quotes around six seconds to an assessment result. There are no machine profiles to set up and no route to load before you can start.

It measures three vibration parameters:

Readings are metric, which suits Australian maintenance records and severity charts without any conversion.

How a Vibration Check Works

1. Power on. Hold the power button for just over a second. The meter opens on the unit you last used.
2. Choose your unit. In standby, cycle through LO m/s², HI m/s², mm/s and mm.
3. Position the sensor. Press the tip against the test surface at 90°. An angled tip affects accuracy.
4. Measure. Hold the measure button until the reading settles, then release. The value holds on screen automatically.
5. Save it. The screen prompts you to save, and one press stores the result as a numbered record.

Fluke’s tip for the acceleration range: the meter doesn’t measure frequency, so you won’t know in advance which band your vibration sits in. Take a reading on both LO and HI, and if they differ, use the higher value to judge the machine’s condition.

Three Ways to Reach the Measurement Point

Machines are rarely laid out with the tester in mind. Guards, tight plant rooms and awkward mounts can all get in the way, so the 802EN supports three measurement set-ups:

With an external sensor connected, the screen shows ACCY and the internal sensor switches off automatically, so it’s clear which one you’re reading from.

Listen to the Machine as Well

The 3.5 mm audio output lets you plug in your own headphones and listen for unusual machine noise. It’s a handy second opinion when a number looks borderline, or when you want to compare a suspect machine with a healthy one nearby. Headphones aren’t supplied.

Making Sense of the Reading

A number only helps if you’ve got something to compare it with. The 802EN gives you the reading, and you interpret it against a reference. Two approaches work well.

Compare against ISO 10816-1. Fluke’s datasheet includes a severity chart based on this standard, which gives general guidelines for vibration measured on non-rotating machine parts. Compare your mm/s reading with the column for your machine class:

As a rough guide to the classes:

• Class I: smaller machines, such as production electric motors up to 15 kW
• Class II: medium machines, typically 15 to 75 kW motors without special foundations, or rigidly mounted machines up to 300 kW on special foundations
• Class III: large prime movers and rotating machines on rigid, heavy foundations
• Class IV: large machines on relatively soft foundations, such as turbo generator sets and gas turbines over 10 MW

Track your own baseline. For many sites, the trend is more useful than any single figure. Take readings at the same marked point, in the same unit, under similar load. A machine that’s still rated acceptable but has climbed steadily over three months deserves more attention than one that’s sat at the same level for years.

Where the Fluke 802EN Earns Its Keep

• Plant and manufacturing maintenance: screen motors, gearboxes, compressors and conveyor drives during routine rounds.
• Food and beverage processing: check production-line machinery between runs, keeping the meter away from wet and washdown areas.
• Power generation and process plants: give operators and fitters a consistent first check on auxiliary pumps and fans, within the limits of the site’s hazardous-area rules.
• Building services and HVAC: check cooling tower fans, air handling plant, chillers and circulation pumps before a noisy fan turns into a tenant complaint.
• Water and pumping stations: compare duty and standby pumps, and record readings before and after a bearing change or repair.
• Training: the simple controls and clear units make it a practical teaching tool for vibration basics.

Built for the Daily Rounds

At 220 g, the 802EN is easy to carry all shift, and its soft case keeps it protected in the toolbag. Two AAA batteries provide up to 25 hours of measurement time, so a spare set is cheap insurance and easy to find. The built-in flashlight helps in dim plant rooms and under guards, and the unit powers itself off after five minutes of inactivity to save battery.

Up to 99 readings stay in memory for review on the meter. Once the memory is full, the oldest record is overwritten, so transfer anything you want to keep into your maintenance log regularly.

It has also passed a 1 m drop test. That’s useful protection for an accidental knock, but treat it as a safety margin rather than a licence for rough handling. The piezoelectric sensor is the heart of the meter, and Fluke cautions against hitting, shaking or dropping it.

Is the 802EN the Right Vibration Meter for You?

The 802EN is a screening meter, and it does that job well. It won’t diagnose the root cause of a fault for you. If your team needs automated bearing assessment or connected data, a higher-tier Fluke model is likely a better match.

Need to pinpoint why a machine is vibrating? The [Fluke 810 Vibration Tester] is designed to identify and prioritise mechanical problems. Many teams screen first, then send only the machines that need it for deeper analysis.

Technical Specifications

What is the Fluke 802EN vibration meter?

The Fluke 802EN is a handheld vibration meter for screening the overall vibration of machines such as motors, pumps, fans and gearboxes. It measures acceleration, velocity and displacement using a built-in piezoelectric accelerometer, and it stores up to 99 readings. Maintenance teams use it for quick checks that show which machines need further attention.

How do you use the Fluke 802EN?

Turn the meter on, choose a unit, and press the sensor tip against the machine at 90°. Hold the measure button until the reading is stable, then release it. The value holds on screen and can be saved with one press. Compare the result with a severity chart or the machine’s previous readings.

What can the Fluke 802EN measure?

The Fluke 802EN measures acceleration from 0.1 to 199.9 m/s² peak, velocity from 0.1 to 199.9 mm/s rms, and displacement from 0.001 to 1.999 mm peak-peak. Its sensor has a typical frequency response of 10 Hz to 15 kHz. It can’t measure the frequency of the vibration.

What vibration level is acceptable for an electric motor?

It depends on the machine’s size and mounting. On the ISO 10816-1 chart in Fluke’s 802EN datasheet, a small Class I machine such as a motor up to 15 kW is rated Good at 0.71 mm/s rms, Satisfactory at 1.12 to 1.80 mm/s, Unsatisfactory at 2.80 to 4.50 mm/s and Unacceptable from 7.10 mm/s.

What is the difference between a vibration meter and a vibration analyser?

A vibration meter gives a quick overall reading of how much a machine is vibrating, which helps you decide whether it needs attention. A vibration analyser looks deeper into the vibration signal to help identify the likely cause. The Fluke 802EN is a screening meter, so a further diagnostic step may be needed once it flags a machine.

Frequently Asked Questions

What is the Fluke 802EN used for? It’s used to screen the overall vibration of machinery such as motors, pumps, fans, compressors and gearboxes. Maintenance technicians use the reading to decide whether a machine can keep running or needs further investigation.

Does the Fluke 802EN tell me if a machine is good or bad? The 802EN gives you a vibration value to compare with a reference. Fluke’s datasheet includes an ISO 10816-1 severity chart and suggested limits for common equipment types, or you can compare the reading with that machine’s previous results.

Can the Fluke 802EN diagnose bearing faults? No. The 802EN measures overall vibration and doesn’t offer a dedicated bearing assessment or identify the root cause of a fault. Fluke’s 805 FC adds a Crest Factor+ bearing assessment, and the Fluke 810 is designed to help identify mechanical problems.

What is the difference between the LO and HI acceleration settings? LO covers 10 Hz to 1 kHz and HI covers 1 kHz to 10 kHz. Because the meter can’t measure vibration frequency, Fluke recommends taking a reading on both settings and using the higher value if they differ.

Does the Fluke 802EN come with an external sensor? No. The external sensor is part of the optional 802ES accessory kit, along with an extender, magnet base and M12 RF connector spring cable assembly. The meter comes ready to use with its built-in sensor.

Are headphones included? No. The meter has a 3.5 mm stereo audio output, but you’ll need to supply your own headphones.

How many readings can the Fluke 802EN store? It stores up to 99 readings. When the memory is full, the meter automatically deletes the earliest reading to make room for the new one.

Can I transfer readings to a computer? The specifications for the 802EN don’t list a USB or wireless data connection, so plan on reviewing readings on the meter and entering them into your maintenance records by hand. If you need connected data, consider the Fluke 805 FC.

Can the Fluke 802EN be used in wet or hazardous areas? No. Fluke warns against using it around explosive gas or vapour, or in damp or wet environments. It’s rated IP40, so it isn’t protected against water.

What warranty does the Fluke 802EN have? The meter has a 1-year limited warranty from Fluke, starting from the date of shipment. Parts, product repairs and services are covered for 90 days. Exclusions apply, including disposable batteries and damage from misuse.
