A new sensor which accurately measures the Direct Normal Irradiance (DNI) without the requirement of a sun-tracker. It features a rotating mirror, which only reflects the sunbeam onto a thermal detector. The pulsed analog output can work with dataloggers with a pulsed analog input or peak hold function. The analog pulse (0-5V) is proportional to the DNI.  

It can be used in combination with any pyranometer to measure the DNI and Global Horizontal Irradiance (GHI). Hence the Diffuse Horizontal Irradiance (DHI) can be calculated. 

A revolutionary method to capture the direct sunbeam. MS-90 is a reinvention of the MS-093 sunshine duration meter, which is a reliable and accurate sunshine duration meter, which has been deployed within the AMeDaS network in …
