Endress+Hauser adds Heartbeat Technology to its Micropilot FMR5X free-space radar and FMP5X Levelflex guided radar level transmitters. Heartbeat Technology is an on-board diagnostics and instrument verification system that continuously monitors the status of mechanical, electromechanical and electronic components in the sensor, and sends alerts when it detects a problem. Alerts are sent in accordance with NAMUR recommendation NE 107 and are displayed at the device. The built-in diagnostics can detect process problems such as build-up or foam before failure occurs. Verification information, reports, diagnostics alerts and instrument data can be viewed at the control and monitoring system.
