Description

The anti-soiling system which can be applied to the MS-56 Pyrheliometer will keep the Quartz window free of sand, dust, rain and snow. In desert environments soiling sometimes becomes an issue as the Irradiance measurement can be affected.

The MS-56 front window has a standard integrated heating system to prevent any snow, ice or condensation.  In combination with the BPI Air-Shield best possible measures can be taken for reliable unattended operation. 

The working principle, an effective "Air-Shield" created by a high flow of filtered air in front of the sensor window to protect against dust, insects and dirt buildup. The air is filtered with a 3-stage high efficiency particle filter and then accelerated in an air turbine. From the turbine, a flexible hose supplies the air trhough the injector head in front of the pyrheliometer window.

The system can be easily attached and retrofitted to any installed MS-56 pyrheliometer. The AirShield system can be either grid-connected or operated through a solar power battery system to allow remote off-grid operation.
