A signal peaks or falls and you need to know; it is the ultimate in ensuring a safe process.

That is why a limit alarm trip can trigger the response needed to maintain normal, and safe, operations. A limit alarm trip monitors a process signal (such as one representing temperature, pressure, level or flow) and compares it against a preset limit. If the process signal moves to an undesirable high or low condition, the alarm activates a relay output to warn of trouble, provide on/off control or institute an emergency shutdown.
