SMP12 Pyranometer

The new SMP12 is fast response spectrally flat Class A pyranometer that combines solid-state dome heating, with no moving parts, and best-in-class surge protection to maximize accuracy and minimize maintenance.

The SMP12 combines proven sensor and diffuser technology from the RaZON+ PH1 and PR1 radiometers with an enhanced version of the Smart interface and the low maintenance of the SMP10.

The SMP12 has an internal drying cartridge that will last for at least 10 years if the housing is not opened. This further reduces maintenance significantly.

Additional features based on customer feed-back are:

- Tilt sensor to enable remote checks of whether the pyranometer mounting alignment has been disturbed.

- Internal humidity monitor to provide confidence that the sealing has not been compromised, for example by an accidental impact.

The SMP12 has a 2-wire RS-485 Modbus® RTU interface but, unlike the other SMP models, it does not have an analog output. The characteristics of the thermopile detector provide a fast response time of less than half a second. The wide power supply range from 10 to 30 VDC makes integration into solar energy plant performance monitoring stations easy. SMP12 has class-leading electrical protection: 2-stage surge and reverse polarity on the power input and 3-stage surge protection on the RS-485 data lines.

Like all SMP series pyranometers, the calibrated sensitivity is stored in memory and the Modbus® irradiance value is directly in W/m2. Pyranometers can be exchanged or recalibrated and no changes in the plant monitoring data logger or SCADA system are needed.

SmartExplorer Windows™ software provides: data logging on a PC, display of data,  changing RS-485 communication settings, setting the Modbus® address – and more. SmartExplorer is free and can be found under the ‘Downloads’ tab of this webpage.

FAQ

  • What type of pyranometer can I use for my fixed PV panels farm?
    • For this application the CMP10 and SMP10 are advised as they have an internal drying cartridge that will last for at least 10 years.

      Please note that the pyranometer needs to be mounted in the same angle (POA) as the PV panel. 

       

      For users that prefer the desiccant visible Kipp & Zonen offers the CMP11 and SMP11 with visible and user changeable desiccant.
