The Helios Pro - Profinet short exposure sensor (P/N 7Z07146) measures high power industrial lasers of up to 12 kW by measuring the energy of a short time exposure to this power. The laser is set to a pulse of from 0.3 to several seconds. It measures the energy and exposure time of this sample of the power, and from this calculates the power. By keeping the pulse energy under 5 kJ, there is no need for water cooling and the Helios power sensor can be kept to a compact size. The Helios Pro - Profinet is a version of Helios that has Profinet and RS232 communications, AIDA compatible connectors for power and data.
