Mettler Toledo ISM technology

ISM (Intelligent Sensor Management) technology from Mettler Toledo is designed to allow users of process analytical equipment to reduce the maintenance costs of loops, while increasing the safety of the production process. Sensors equipped with ISM are continuously monitored for defects and wear to anticipate failure before it happens.

By delivering online sensor status data to the transmitter, an ISM measurement loop is more reliable and generates less maintenance costs than a conventional equivalent loop. For pH loops, the adaptive calibration timer calculates the time to the next calibration based on the actual sensor load and the real-time wear of the sensor. It also enables electronic documentation of the sensor operation, thereby reducing errors and time-consuming paperwork.

ISM-enabled sensors are digital, with integrated electronics for signal conditioning in the sensor head. The fully digital and low-impedance signal transmission secures a trouble-free, humidity-insensitive communication with the transmitter.

The ISM technology is available on a wide range of parameters such as pH, ORP, conductivity, dissolved and gaseous oxygen, TOC and ozone.

In order to fully exploit the benefits of ISM, the iSense Asset Suite allows the user to maximise the performance of ISM sensors over their entire lifetime. Connect an ISM sensor via USB port to a PC or laptop and gain access to various analysis, calibration and documentation applications. ISM can also be integrated into a process control system with Profibus and FOUNDATION Fieldbus digital communication.
