Combining the SHP 1 sensor technology with smart interface advantages makes the SHP1 the best commercially available pyrheliometer. The smart interface not only offers versatile outputs, the integrated temperature sensor and digital polynomial functions also provide individual correction for the temperature sensitivity of the detector from -40°C to +70°C.
The increased response time and the standard output help interchange instruments for recalibration. Due to the Modbus protocol, a range of instrument status and configuration information is available, with user-selectable options.
SHP1 pyrheliometers have very low power consumption so that internal heating does not affect the detector performance. SHP1 pyrheliometer is available in two versions, one has an analogue output of 0-1V, the other is 4-20mA. Both have a 2-wire RS-485 interface with Modbus® (RTU) protocol. The analogue outputs enable easy connection to virtually any data logger without the need for sensitive mV inputs.
