Page 6: Identification
1. IDENTIFICATION 1.1. General The Fike Explosion Pressure Detectors are designed to continuously measure the pressures inside the protected hazards. The extremely fast response time of the Ceramic pressure detector allows the Explosion Protection Controller (EPC) to take more than one million samples every second. Using the same instantaneous speed, this information is then processed to determine if the pressure change is that of a developing explosion. -
