Pyranometer RK200-03

Jual Alat Uji Pemantau Cuaca, Weather Station, AWS, Data Logger, Sensor Kecepatan Angin

Deskripsi

The RK200-03 Pyranometer diproduksi berdasarkan prinsip thermoelectric; elemen penginderaan dibuat dengan thermopiles berlapis-lilitan dengan kontak ganda. Permukaannya dilapisi oleh lapisan hitam dengan tingkat penyerapan tinggi. Kontak panas pada permukaan sensor, sementara persimpangan dingin terletak di dalam tubuh, perbedaan suhu antara sambungan panas dan dingin menghasilkan gaya gerak listrik, efek termoelektrik sebanding dengan radiasi matahari. Untuk mengurangi efek suhu sekitar, sirkuit kompensasi suhu dirancang di sini untuk mengurangi efek pada properti produk.

 OUTPUT CHARACTERISTICS

 0-20mV
Solar radiation values(W/m2)= Voltage output value(μV)/sensitivity coefficient(μV*W-1*m2),
Each product is with one sensitivity coefficient respectively (It is mentioned on the product’s label)
 0-5V
Solar radiation values(W/m2)=(V/5)*2000(Where V is output voltage value,unit:V )
 4-20mA
Solar radiation values(W/m2)=(I-4)/16*2000(Where I is output current value,unit:mA )
 RS485
MODBUS-RTU

 DIMENSION

 MOUNTING & MAINTENANCE

 The sensor should be installed in the open air without any shield above the sensing surface .
 The sensor connector should be faced to the north, fix it after the horizontal position is well adjusted.
 Please check the filter cover regularly & make sure it is clean.
 Please do not remove or loose the filter cover,otherwise the accuracy will be affected.
 Please make sure the desiccant to be dry (If the color of desiccant is changed from blue to red, it should be replaced)
 Protection cover is not necessary in general rainfall, but if prolonged heavy rains or hail, the protective cover is recommended to be installed.
 The sensitivity is recommended to be re-calibrated after two years use.
