- Fast response time
- RS-485 Modbus®
- 5 year warranty (*)
- Temperature corrected
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 +70 °C. The improved response time and the standardised output make it easy to interchange instruments for recalibration. Thanks to the Modbus® protocol, a range of instrument status and configuration information is available, with user-selectable options.
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. All the inputs and outputs are protected against reversed polarity, over voltage and short-circuits.
The SHP1 pyrheliometer is available in two versions, one has an analogue output of 0-1 V, the other is 4-20 mA. Both have a 2-wire RS-485 interface with Modbus® (RTU) protocol.
The analogue outputs allow easy connection to virtually any data logger without the need for sensitive mV inputs. Modbus® interfaces directly to RTUs, PLCs, 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. The SHP1 is supplied with a comprehensive, traceable, calibration certificate.
