Description
SHP1 Pyrheliometer from Kipp and Zonen.
The SHP1 pyrheliometer takes the accuracy of the analogue CHP1 sensor technology and adds a smart interface (RS485 Modbus). As a result, the SHP1 has a faster response time and can be integrated with a SCADA system. It is the ideal sensor for measuring Direct Normal Irradiance in meteorological and utility-scale solar farm prospecting.
With integrated temperature sensor and digital polynomial functions, the SHP1 pyrheliometer provides individual correction for the temperature sensitivity of the detector from -40 °C to +80 °C.
SHP1 pyrheliometers have extremely low power consumption so that internal heating does not affect the detector performance. They operate from a wide range of supply voltages, making them ideal for power-critical applications, and the power input is protected against reversed polarity.
Serial Output
Two versions are available, SHP1-V has an analogue output of 0-1 V, SHP1-A is 4-20 mA. Both have a 2-wire RS-485 serial interface with Modbus® RTU protocol that provides a range of instrument status and configuration information, with user-selectable options.
The analogue outputs allow easy connection to virtually any data logger without the need for sensitive mV inputs. Modbus® interfaces directly to PLC and SCADA systems, industrial networks and controllers. A recalibrated instrument keeps the same analogue and digital measurement ranges, saving time by eliminating re-scaling of data collection equipment.
