Thermopile Detector, 5 kW, 50 mm, 0.19- 11 µm, Water Cooled

The 919P-5kW-50 Water Cooled Thermopile Sensor is a general purpose thermal sensor measuring optical power up to 5000 W. It's BB absorber type is spectrally flat and covers the wavelength range 190 nm to 11 µm. It has a large active diameter of 50 mm and can measure continuous optical power from 20 to 5000 W. 3/8" QuickConnect fittings are;mounted on the sensor head for convenient connection of cooling water tubes. At full power, minimum 5 liter/min water flow rate is required and 8 liter/min is recommended (water temperate 18 to 30 C, with < 1 °C/min variation). It has a 1/4-20 tapped hole for post or plate mounting and includes a 2.25 inch long 1/2 inch diameter post with a 1/4-20 tapped hole on both ends.
