1.1.2.7 High Power Thermal Sensors 1.1.2.7.4 Very High Power Water Cooled Thermal Sensors 10kW to 120kW Features ֺ ֺ Highest powers ֺ ֺ Water cooled ֺ ֺ Up to 120kW ֺ ֺ Ø200mm aperture Laser Beam Absorbing Chamber and Power Measuring Unit Laser Beam Path Measuring Highest powers to 120kW Measurement Type Water cooled beam absorber chamber with deflecting cone. Separate power measuring unit monitoring input and output cooling water flow and temperature 0.9 –1.1µm (a) Ø200 10kW – 120kW ±20W with stable water temperature Less than 1% Designed for near Gaussian beam. Beam to be focused with 500 - 1000mm FL lens and meter placed so that the 1/e2 beam diameter on reflecting cone is Ø100mm in diameter (see sketch above) Beam to be centered on deflecting cone ±5mm and parallel ±2degrees 40s at flow rate 60 liter/min and 60s at flow rate 20 liter/min 5 (a) Water flow rate, 60 liters/min at max power. Inlet temperature 15-20degC. Inlet water temperature rate of change <0.3degC/min at full power, proportionately less at lower power (b) Consult Ophir representative 4 bar at 60 liter/min flow rate Up to 4 meters in each direction of 1” OD 13/16” ID flexible nylon tubing 1. Cable terminated in DB9 plug with RS232 ASCII output reading power, flow rate and temperature on PC. Cable lengths 10 meters (recommended for access to full data). 2. Cable terminated in DB15 Ophir smart plug reading power. See drawing below Beam Absorber 50kg. Power measuring unit 10kg Spectral Range µm Aperture mm Power Range for Calibrated Reading Power Noise Level Backscattered Power Limitations on Beam Beam Centering Requirements Response Time Power Accuracy +/-% Cooling Requirements Fiber Adapters Water Pressure Drop across Beam Absorber Water Connections Outputs Dimensions Weight kg Version Part number Calibrated for 1.07 µm Minimum flow rate should not be below 20 liter/min. It is recommended that the user install a safety interlock flow switch on the return water line (after beam dump) to immediately shut down the laser if flow rate drops 100K-W sensor is available as well as a Customized Solutions (OEM) sensor upon request. The accessories and graphs referring to 120K-W sensor are also relevant to the 100K-W sensor 120K-W FITTING 2 - for 1" Nylon Hose (Connected to Measuring Unit) (2x) 7 Mounting Holes (2 sides) FITTING 1 - for 1" Nylon Hose (Connected to Measuring Unit) Fitiing for 1" Nylon Hose from Sensor (Connected to FITTING 2) USB-B Connector Beam Dump Fitting for 1" Nylon Hose to Sensor (connected to FITTING 1) Fitting for 1" Nylon Hose from Chiller (HOT WATER OUT) (2x) Mounting Holes For M4 Flat Screws 2 sides 335 (4x) Rubber Feet (Glued with Adhesive Transfer Tape) Fitting for 1" Nylon Hose from Chiller (COLD WATER IN) For latest updates please visit our websi
