Description
SHP1 Pyrheliometer by Kipp and Zonen
The Kipp and Zonen SHP1 pyrheliometer is a world-leading irradiance sensor for measuring direct normal irradiance.
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. The power input is protected against reversed polarity, over voltage and short-circuits.
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.
