Food & beverage

Food and beverage production relies on continuous operation to meet population demands while minimizing variation. Line stops directly impact food quality, yields and potentially contribute to contamination. Monitoring cooling systems and other critical equipment minimizes potential downtime and ensures high levels of operation to meet the growing demand across the globe.

Beyond the main generators at energy plants is a supporting network of equally critical motors and equipment. Downtime in this equipment will impact on the overall power output of the plant. By continuously monitoring this equipment, manual maintenance routines can be removed, costs reduced and efficiency process improved.

Water utilities

Droughts occur more and more frequently in today's world. As a consequence, water resources need to be managed more effectively. The Smart Motor Sensor provides a cost efficient and reliable solution for your remote pump operation. For example, it allows a better use of aquifers. It can also benefit other activities such as the proliferation of wastewater treatment, water purification, desalination and transfers between basins.

In the paper industry, the proper functioning of paper machine motors is vital. The failure of one of the motor that drive the different rollers or pumps of the process will be enough to cause a production stop and loss of material. ADI OtoSense SMS facilitates monitoring of these motors along with others on critical machines that drive pulpers, ensuring production uptime.


Trusted by experts

With the technology of ADI Otosense and in particular with the SMS, we manage to eliminate manual routes of predictive maintenance guaranteeing the reading of data of critical equipment that are not always working, we obtain very detailed and reliable information of the state of the machine, and we are more efficient with our maintenance staff dedicated to accurate diagnostic fault repairs.
