The sensor represents the modern trend in radiation sensing using photodiodes, sometimes referred to as a silicon pyranometer. This requires less compensation and less maintenance.
The photodiode measurement head has a optical filter which also acts as a cosine corrector.
Screws with stainless steel springs and a built-in spirit level allow for correct sensor positioning.
The sensor is built ruggedly for long durability and lengthy inter-service intervals. All exposed parts are made of corrosion resistant material like hard anodized aluminium or UV resistant engineering plastic. Teflon top measurement tip reduces chances of dust collecting on the sensor.
High quality two core screened teflon coated cable is supplied in standard or custom lengths.
Mounting is by way of three mounting holes which provide a way of bolting the baseplate onto a secure fixture.
The sensor sports a wide supply voltage range. Outputs other than the standard can be considered in appropriate cases and are offered in customized versions.
