Wireless Vibration Monitoring for Pumps and Motors: How a 90-Day PlusSmart Pilot Works in an ASEAN Plant

Why monthly handheld routes are not enough

Most plants in Thailand, Indonesia and Vietnam still rely on a technician walking a route with a handheld meter once a month – if the technician is available, the machine is running at normal load, and the measurement points are reachable. Between two visits a bearing can go from “good” to seized: a typical bearing fault on a 75 kW pump develops over 3–10 weeks, with the last, visible stage taking only days. Monthly data points also miss load-dependent faults that appear only at night shift or during a particular product run.

What a wireless sensor measures

• Velocity RMS (10–1,000 Hz) – the ISO 10816/20816 metric used for overall alarms.
• Acceleration and envelope spectra (up to 10 kHz) – early bearing and gear-mesh defects.
• Surface temperature – lubrication and alignment problems, cross-checked against vibration.
• Run-time and run status – operating hours for maintenance planning.

The i-ALERT sensor used in PlusSmart deployments is a triaxial, battery-powered unit (3–5 years battery life, IP67, ATEX option for hazardous areas) that attaches with a magnet or epoxy stud. No cable trays, no conduit, no permits for hot work.

Setting alarms that mean something

ISO 10816-3 gives zone limits by machine class – for a 15–300 kW motor on a rigid foundation roughly 2.8 mm/s (plan a repair) and 4.5 mm/s (danger). Use them as a starting point only. The practical method is to record a baseline during the first two weeks of healthy running, then set warning at 1.5× baseline and alarm at 2× baseline per axis, and let the analytics flag rate-of-change rather than absolute level. This avoids both nuisance alarms on rough-running but stable machines and silent failures on machines that normally run very smoothly.

What the 90-day pilot includes

1. Criticality survey (remote or on site, 1 day) – rank assets by downtime cost × failure likelihood; choose 10–20 points: cooling-water pumps, ID/FD fans, main compressors, kiln or mill drives, boiler feed pumps.
2. Installation (1 day) – sensors, one gateway (4G or plant LAN), dashboard activation, 2-hour training for the maintenance team.
3. Monitoring (90 days) – automatic alerts to WhatsApp/email, fortnightly review calls with a certified vibration analyst (ISO 18436 Cat. II/III), work-order recommendations.
4. Evaluation – documented findings, avoided-failure estimate, proposal for plant-wide or multi-site roll-out, subscription or CAPEX model.

Typical findings in ASEAN plants

Across pilots in Vietnam, Thailand and Indonesia the same patterns recur: misalignment after seasonal pump re-coupling, bearing damage from over-greasing, soft-foot on fans mounted on corroded bases, and belt-drive looseness. Humidity and monsoon-season condensation accelerate bearing corrosion, so trend monitoring is more valuable here than in temperate climates. A single avoided failure on a critical pump – typically 8–24 hours of lost production plus emergency logistics – usually exceeds the cost of a 20-point pilot.

Integration and data ownership

Dashboards are in English (Thai and Bahasa Indonesia reports available), alerts can be routed to CMMS or SAP PM, and data can be hosted regionally (Singapore) or on premise where corporate IT policy requires it. Customers own their data and can export it at any time.

How to start

Send us a list of 10–20 machines (power, speed, type) and your plant location. We propose sensor positions, a quotation and a pilot date, and coordinate with local partners in Thailand and Indonesia. For background on the standard, read our Thai and Indonesian ISO 10816 guides.
