The Helios-Profinet measures high power industrial lasers of up to 12kW 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. The Helios-Profinet 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 sensor can be kept to a compact size. Helios-Profinet is a version of Helios that has Profinet and RS232 communications. For EtherNet/IP communication please see Helios-EtherNet/IP
