1. A monitoring system for a pressure relief device, comprising:
- a release sensor configured to provide an indication when the pressure relief device activates;
a first communication device connected to the release sensor and configured to send a wireless transmission having an activation signal when the indication is provided by the release sensor and configured to send a wireless transmission having a status signal when a first predetermined period of time elapses without the release sensor providing the indication; and
a second communication device configured to receive the wireless transmissions from the first communication device and to generate a warning signal when the activation signal is identified, the second communication device further configured to send an interrogation signal to the first communication device when the period of time elapses without receiving the wireless transmission having the status signal.

Abstract
A system and method for monitoring a pressure relief device are provided. The system includes a release sensor that provides an indication when the pressure relief device activates. A wireless transmitter is connected to the release sensor and sends a wireless transmission having an activation signal when the indication is provided by the release sensor. A receiver receives the wireless transmission from the transmitter and generates a warning when the activation signal is identified.
