The SMP11 smart pyranometer combines class leading sensor technology with industry standard digital and analogue amplified outputs. Based on the proven CMP11 technology, the SMP11 adds Modbus® interface, improved response time and temperature corrected measurement data.Enquire about this product
- RS-485 Modbus® RTU interface
- 0 – 1 Volt or 4 – 20 mA analogue output
- 5 year warranty (*)
- Active temperature correction from -40°C to +80°
The wide and low power supply range from 5-30 VDC makes integration in meteorological stations easy. The SMP is protected against over voltage, reversed polarity and short circuiting. Because all SMPs have identical sensitivity and connections, exchanging instruments for recalibration is easy.
PC Software for data logging, display of data and Modbus® address setting is provided as standard.
SMP11 measures incoming global solar radiation with a 180° field of view. Ideal for solar radiation measurements in both Meteorological and Solar Energy applications that require the Modbus protocol or amplified outputs.
