SR11-TR pyranometer

First class pyranometer with 4-20 mA transmitter

Back to overview

SR11-TR is a solar radiation sensor that is applied in general high accuracy observations. SR11-TR pyranometer complies with the first class specifications of the ISO 9060 standard and the WMO Guide. It houses a 4-20 mA transmitter for easy read-out by dataloggers commonly used in the industry.

SR11-TR measures the solar radiation received by a plane surface from a 180o field of view angle. This quantity, expressed in W/m2 is called “hemispherical” solar radiation. SR11-TR pyranometer can be employed outdoors under the sun, as well as indoors with lamp-based solar simulators. Its orientation depends on the application and may be horizontal, tilted (for plane of array radiation) or inverted (reflected radiation).

Using SR11-TR is easy. The pyranometer can be connected directly to commonly used data logging systems. The irradiance in W/m2 is calculated by using the transmitter’s output. In SR11-TR’s standard configuration, the 4 to 20 mA output corresponds to a transmitted range of 0 to 1600 W/m2. This range can be adjusted at the factory upon request.

SR11-TR pyranometer design

SR11-TR pyranometer employs a thermal sensor with black coating, two glass domes and an anodised aluminium body, which also houses the transmitter.
