ISM™ is a digital technology for process analytics. Measurements from ISM sensors are highly reliable and help you maintain process consistency. Data and ISM's advanced sensor diagnostics can be easily transferred to wherever needed and support true predictive maintenance planning.

ISM solves all these problems.
If sustaining process consistency is your goal, you need analytical instrumentation that you can fully rely on. ISM sensors are extremely valuable in this regard.
You want sensor data from measurement point to control room to remote location. Integrating ISM into your facility's infrastructure is fast and straightforward.
Labor is a scarce resource, and you need to prioritize efforts. Sensors should be maintained only when needed and never too late. With ISM, you'll perform the right maintenance at the right time.

Intelligent Sensor Management, or ISM, is a platform developed by METTLER TOLEDO that uses digital technology to improve the performance of our analytical sensors and simplify how sensor data such as measurement results or predictive diagnostics information can be integrated into production facilities, how sensors are handled, and how they are maintained.
In process analytics, sensor management refers to how sensors are utilized, maintained, handled, and monitored. Sensor management could include scheduling and conducting sensor maintenance, and ensuring replacement sensors are always available.
An analog sensor and an ISM sensor for measuring an analytical parameter are very similar. They will both have many of the same components and will measure the parameter in the same way. However, whereas an analog sensor outputs an analog signal that is converted into a displayed measurement by the transmitter it is connected to, ISM sensors contain a microchip that makes the calculation and outputs the measurement as a digital signal. Because the signal is digital, it is very robust and is immune to electromagnetic noise and interference. This makes the measurement more accurate than for analog sensors. As well as calculating the measurement, the microchip contains advanced diagnostics tools that predict when sensor maintenance or replacement should be performed.
A digital process analytical sensor is one in which the measurement (e.g., pH level or oxygen concentration) is calculated within the sensor and converted from an analog signal to a digital signal. This is achieved through use of a microchip within the sensor.
Intelligent sensors such as ISM sensors are able to carry out a number of functions that analog sensors cannot. This includes the ability to monitor themselves for maintenance needs, store calibration data, and output other information such as their sensor type and serial number.
In digital sensors, the principle for measuring analytical parameters is identical to that of analog sensors; however, the inclusion of a microchip in the sensor provides numerous features and benefits that are not possible with analog sensors.
