Stray Energy Indicator for Pyrotechnic Applications

A compact and portable system is used to monitor and store real-time measurements of stray energy through a pyrotechnic firing circuit using infrared technology. The infrared sensor is mated to the NASA Standard Initiator simulator, and is calibrated such that the current input through the bridgewire can be determined through measurement of the temperature. Because the sensor is noncontact, if the bridgewire melts during the test, the sensor may be reused.
