The combination of the CHP 1 sensor technology with smart interface advantages makes the SHP 1 even better, and with faster response.
The smart interface not only provides 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 +80°C. The standardized output makes it easy to interchange instruments for recalibration.
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.
Two versions are available: SHP 1-V with an analogue output of 0 - 1 V; SHP 1-A with an analogue output of 4 - 20 mA. Both have in addition 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.
SmartExplorer Windows™ software for data logging, display of data and Modbus® address setting, can be downloaded from the Kipp & Zonen / Ott HydroMet webpage.
