Acromag offers a full line of process alarms for many applications. These units monitor your setpoint limits for various process parameters and trip a relay to govern actions under alarm conditions. Typical uses involve triggering warning lights, audible alarms, or data loggers. Alarms can also turn devices on/off or open/close valves. Advanced applications are able to detect a significant deviation between two signals, a rapid change in measured values, or even capture a peak value for a process.
