Description

Measure albedo

What is an albedometer?

An albedometer is an instrument that measures both global and reflected solar radiation and, by calculation, the solar albedo, or solar reflectance for a particular ground surface. An albedometer is composed of two pyranometers, both installed horizontally, the downfacing one measuring reflected solar radiation. 

Using the albedometer is easy. The irradiance in W/m2 is transmitted via the Modbus protocol over 2-wire RS-485. The working principle and specifications of the pyranometers can be found in the pyranometer user manuals. The pyranometers can be connected directly to commonly used data logging and SCADA systems.

To create an albedometer, two sensors are combined with one AMF03 albedometer mounting kit. AMF03 includes a fixture with a rod for mounting purposes and a glare screen. The user assembles these modular components into an albedometer. The modular design facilitates maintenance and calibration.

SRA100-D1: industrial-grade, high-accuracy and reliable

SRA100-D1 consists of two identical pyranometer models SR100-D1, one facing up, one facing down. SR100-D1 complies with – Industrial-grade – Immunity, Emission, Electrical, Environmental and Safety requirements for use in these outdoor and industrial environments, greatly improving measurement reliability. Ease of operation is further enhanced through extended functionality and diagnostics.  

If you need a heated albedometer with an onboard tilt sensor, please consider the SRA300-D1 model.

Immunity to high voltages and currents - surges

SR100-D1 is tested and classified for Industrial Environments according to IEC 61326-1 and IEC 61000-6-2. When designing a measuring system, pyranometer users may reach several levels of immunity. With the optional Surge Protection Device SPD01 this immunity can be increased to 4 kV. 

Suggested use

  • PV monitoring with bifacial solar modules
  • high-accuracy meteorological observations
  • extreme climates (tropical / polar)
