Always Monitoring

24/7/365

Your machines don’t sleep.
Neither should your sensors.

Industrial Monitoring Sensors—rugged, hermetically sealed, hazardous-area approved. Built for permanent installation on rotating machinery in the harshest plant environments.

How It Works

From sensor to decision

01

Install

Mount industrial sensors directly on bearing housings, motor frames, or machine casings. Stud mount, adhesive, or magnetic—stainless steel housings survive oil, water, and vibration.

02

Monitor

Continuous 4–20mA or ICP® signals feed directly into your existing PLC, DCS, or condition monitoring system. No special software required—the data flows into what you already use.

03

Alert

Set alarm thresholds in your control system. When vibration trends upward, your team gets notified. Vibration switches can trigger automatic shutdown to protect critical machinery.

04

Act

Schedule maintenance on your terms. Replace bearings during planned outages, not emergency shutdowns. The data tells you what needs attention and how urgent it is.

Continuous Protection

Your machines are running. Are you listening?

We’ll help you design a monitoring system that fits your plant, your machines, and your existing infrastructure.
