Product Description RK200-03 Class B First Class Pyranometer with 4-20mA/RS485 Output for Solar Farms Product DescriptionRK200-03 Pyranometer Crafted with precision, the RK200-03 Pyranometer harnesses cutting-edge thermoelectric principles, featuring sophisticated sensing elements meticulously fashioned from winding-plated thermopiles enriched with multiple contact points. The surface is adorned with an advanced black coating optimized for maximum absorption efficiency. Ingeniously designed, the sensor's hot contacts grace the exterior while the cold junction resides internally. This differential in temperature engenders an electromotive force, echoing the thermoelectric effect directly aligned with solar radiation. Ingeniously incorporated, a temperature compensation circuit minimizes ambient temperature influences, safeguarding the product's performance integrity.RK200-03 Pyranometer Features:Designed to meet and exceed WMO standards, ensuring unparalleled reliability.Engineered to operate seamlessly in even the harshest environments.Exhibits exceptional sensitivity for precise solar radiation measurement.Equipped with a horizontal bubble for effortless alignment.Features robust double transmission glass for durability and accuracy.Includes a clear visual desiccant window for easy maintenance monitoring.Designed for straightforward installation, saving time and effort.RK200-03 Pyranometer Applications:Perfectly suited for solar energy and photovoltaic power generation systems.Ideal for agriculture and forestry monitoring applications.Essential for precise crop growth monitoring.Versatile for tourism eco-environmental assessments.An indispensable tool for weather station setups.1. Select a 0-20 mv signal output for a power supply-free operation.2. Opt for RS485 output signal to engage the external signal conversion module (98*66*49mm). RK200-03 Pyranometer Output Characteristic:0-20mV Calculate solar radiation values (W/m2) by dividing the voltage output value (μV) by the sensitivity coefficient (μV*W-1*m2). Each unit comes labeled with its unique sensitivity coefficient.0-5V Determine solar radiation values (W/m2) by using the equation (V/5)*2000, where V is the output voltage value in volts.4-20mA Ascertain solar radiation values (W/m2) using (I-4)/16*2000, with I representing the output current value in mA.RS485 Utilizes MODBUS-RTU protocol for efficient data communication.Output CharacterRadiation output (W/m2) is determined by dividing the voltage output value (μv) by the sensitivity coefficient (μv*w-1*m2).Each unit comes with a distinct sensitivity coefficient, clearly stated on the product's label.SPECIFICATIONSItemTechnical SpecificationISO9060:2018Class BISO9060:1990First classSpectral range280~3000 nmOutput0-20mV4-20mA,RS485Supply/12-24VDCRange0-2000W/m2Sensitivity7-14μV/(W/m2)Non-linearity±1%(100~1000W/m2)Response time≤30s(95%)Zero drift( temperature drift:5k/h)<±4W/m2Stability<±1.5%/yearDirectional response±20W/m2Temperature effect<4%(-10~40oC)Operating temperature-40oC-+80oCRecalibration interval2 yearsCalibration basisISO9847Weight(unpacked)0.8kgDimension154*101.5mmTransmission module4-20mA: external,RS485:built-inDesiccantBuilt-inInstallation bracket(optional)Horizontal bracket or adjustableIngress protectionIP67Storage condition10oC-60oC@20%-90%RH Detailed PhotosTo ensure we recommend the right products for your needs, kindly provide us with the following information: 1.
