Features and Benefits

Advanced ISM for low cost of ownership and higher reliability

• Keep your process under control with real-time status information from the sensor for true predictive maintenance.
• The Dynamic Lifetime Indicator (DLI) tells you when the sensor needs to be replaced.
• Only calibrate when necessary: The Adaptive Calibration Timer (ACT) monitors the time to next calibration.

Versatility thanks to mixed-mode input

• The M400 can input either any analog or innovative ISM sensor. You decide which sensor type is best suited for each application.

Minimized maintenance costs

• The Plug and Measure feature allows measurement readiness within seconds.
• Simplified commissioning minimizes risk of installation problems.
