RH5X Mounting Height

Recommended Posts

Hi All

 

Are there any obvious advantages or disadvantages to mounting the RH5X closer to the sensor heights? Particularly in cold and elevated climates?

 

If I were to extend my RH sensor to 80m (for argument's sake), what spec of cabling would I need to use with a standard iPack?

 It is possible to extend the RH-5X cable length for elevated mounting.  As with any of the standard sensors used with Symphonie be sure to use 20 or 18 AWG cables. There is more info on extended cables here: http://www.nrgsystems.com/TechSupport/KnowledgeBase.aspx?id=8&category=7

 The only advantage I see of raising the mounting height of an RH sensor would be to protect it from snowpack and animal rubbing/chewing. While temperature gradient measurement (delta T) is becoming more common in wind resource assessment, I do not know of anyone measuring RH gradients. I think they tend to be pretty consistent at a tower location.

Thanks for the reply. Agreed, the RH gradient is probably minimal across a tower, but regardless I was thinking more of taking my only RH measurement as close to the hub height as possible. I haven't read anything that suggests this is done very often (if ever), but I'm operating in a mountainous climate with harsh winters and the idea was to collect atmospheric data under sensor positions closely resembling those outlined in this paper on turbine icing losses:
