Application Note: Improve Your Processes with ISM
An advance in sensor technology
Many years of experience in the field of industrial measurement systems form the basis of METTLER TOLEDO’s competence. Now, with the groundbreaking Intelligent Sensor
Management (ISM) concept, we combine our accumulated knowledge with digital technology and processing power for advanced sensor diagnostics and improved process safety.
The digital solution
Specific to ISM sensors is that signal processing takes place within the probe head itself. Measurements are then sent digitally to the transmitter. Digitizing the analog signal where the
sensing element is is a logical idea because the low impedance digital signal is much less prone to electromagnetic interference, or degradation due to cable length ormoisture in the environment.
ISM sensors continuously perform their own “health check” and monitor critical parameters to provide early warning of maintenance. This invaluable diagnostic data is displayed in a clear manner on the transmitter. Knowing when calibration, maintenance and sensor replacement are required greatly improves process safety and allowsmaintenance to be planned in advance.
