Apogee silicon-cell pyranometers feature a silicon-cell detector. — Accurate and stable global shortwave radiation measurement in W m^-2.

Apogee Instruments' silicon-cell pyranometers feature a silicon-cell detector. The sensors are accurate, stable, durable, and cost-effective, the results of continual refinement of design.

Accurate Measurements - ISO 9060:2018 Class C

Calibration in controlled laboratory conditions is traceable to the World Radiometric Reference in Davos, Switzerland. The upward-looking model is cosine corrected, with directional errors less than 20 W m^-2 at 80° solar zenith angle. Long-term non-stability determined from multiple replicate pyranometers in accelerated aging tests and field conditions is less than 2 % per year.

Rugged, Self-cleaning Housing

Patented domed shaped sensor head (diffuser and body) facilitate runoff of dew and rain to keep the diffuser clean and minimize errors caused by dust blocking the radiation path. Sensors are housed in a rugged anodize aluminum body and electronics are fully potted.

Heated Option

A heated pyranometer (SP-230 All-season) is available with a 0.2 W heater to keep water (liquid and frozen) off the sensor and minimize errors caused by dew, frost, rain, or snow blocking the optical path.

Typical Applications

Applications include shortwave radiation measurement in agricultural, ecological, and hydrological weather networks. Sensors are also used to optimize photovoltaic systems.

Mounting

The AL-120 Solar Mounting Bracket with Leveling Plate facilitates mounting the sensor to a mast or pipe. The AL-100 Solar Sensor Leveling Plate is designed to level the sensor while sitting on a flat surface or mounting to a surface.

Output Options

Handheld Meter Options:
MP-100
MP-200

Pigtail Analog Outputs:
0 to 400 mV
0 to 2.5 V
0 to 5 V
4 to 20 mA

Digital Outputs:
Modbus (pigtail)
SDI-12 (pigtail) USB

µCache Package:
PP-100 Package: SP-110 model works with Apogee's µCache Bluetooth Micro Logger.

High Quality Cable

Pigtail-lead sensors feature an IP68, marine-grade stainless-steel cable connector approximately 30 cm from the head to simplify sensor removal for maintenance and recalibration. Cable is shielded-twisted pair wire with a TPR jacket for high water resistance, UV stability, and flexibility in cold conditions.

Warranty and Support

All Apogee products are backed by an industry-leading four year warranty and outstanding customer support.
