Monitoring relays can be used in any application where a change in voltage, current, phase or another factor is a threat or where it provides valuable feedback. For instance, relays are used in alarm systems where a change in voltage indicates that a door or window has been opened or broken. The most advanced Monitoring relays are usually found on factory floors, however, Some of these relays are adjustable. They can be used to monitor different variables and to react in different ways when specific tolerances are exceeded. For example, immediately shutting down a machine may be more dangerous to the device than letting the voltage get over or under norms by a certain amounts, so the relay can be set to react only if it reaches a threshold that is well outside of tolerances. This ensures that conditions that are less than optimal, but hardly catastrophic, don’t result in an automatic and potentially catastrophic shutdown of a machine.
Monitoring relays can be used to protect electronic and mechanical equipment with equally good results.
The following industries are only a few that make use of these devices in various capacities:
- Commercial Kitchens
- Manufacturing Plants
- Electrical Stations
- Elevators and Escalators
- Pumping Stations
There are many more. The technology that has been developed in the last 20 years has made relays even more sensitive and flexible than they have been in the past. This has made industry more efficient and helps to ensure that the highest safety standards can be maintained in factories, power plants and other locations around the world.
