The Helios Pro - EtherCAT short exposure sensor (P/N 7Z07144) 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. 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 sensor can be kept to a compact size. Helios Pro - EtherCAT is a version of Helios that has EtherCAT and RS232 communications, AIDA compatible connectors for power and data. For Profinet communication please see Helios Pro - Profinet. For EtherNet/IP communication please see Helios Pro - EtherNet/IP or Helios Pro EtherNet/IP-M
