提高测量精度延伸清洁间隔可减少零偏移防水零抵消为IP68 5年保修CVF4通风单元通风太阳辐射仪器通过减少灰尘和污垢减少圆顶污染的测量可靠性和准确性。通过热潜水堆的粘性仪和Pyrgeometomers通风稳定辐射计的温度并减少热偏移。集成的加热器可以通过可防止露珠形成,分散沉淀和熔体霜,圆顶上的冰或雪。使用通风和加热最大限度地提高了良好质量数据的上一时间,并延长了清洁间隔。CVF4是低功耗,低维护通风装置。需要维护的唯一部分是进气滤清器,应以规则的间隔检查并在必要时清洁或更换。没有任何工具,该装置提供了5个备用过滤器。有一个5 V脉冲信号,以便可以监控风扇速度。CVF4创造的空气流是独一无二的;它旋转以改善圆顶顶部的分布。 This has now been further improved using an optimally shaped air duct and a new fan that has higher air flow and is waterproof. The interface electronics have also been redesigned. As a result, the improved CVF4 now comes with a 5-year warranty and it is protected to IP68. CVF4 is designed to be used with Kipp & Zonen’s: CMP / SMP pyranometers CGR / SGR pyrgeometer CUV5 / SUV5, SUV-A, SUV-B and SUV-E ultraviolet radiometers CVF4 can be mounted on our SOLYS2 and SOLYS Gear Drive sun trackers and the CM121C shadow ring.
