3.2 General description i-ALERT®2 Equipment Condition Monitor
Description
The i-ALERT®2 Equipment Condition Monitor is a compact, battery-operated monitoring device that con-
tinuously measures the vibration and temperature of the pump power end. The i-ALERT®2 sensor uses
blinking red LEDs and wireless notification to alert the pump operator when the pump exceeds vibration
and temperature limits. This allows the pump operator to make changes to the process or the pump be-
fore a catastrophic failure occurs. The Condition Monitor is also equipped with a single green LED to in-
dicate when it is operational and has sufficient battery life. (i-ALERT®2 Bluetooth Equipment Condition
Monitor option available. The i-ALERT®2 monitor allows customers to identify potential problems before
they become costly failures. It tracks vibration, temperature and run-time hours and wirelessly syncs the
data with a smart phone or tablet the i-ALERT®2 mobile app. More information available on
