Bar30 operating temperature

[EliotBR (Eliot)]

@EliotBR

I’ve brought it up again and will hopefully have a more concrete response soon

Update on this,

@BrianBR

We haven’t tested the Bar30 (or Bar02) to the sensor’s temperature extremes at pressure, so [you] would need to try at your own risk.

I would avoid freezing the sensor in water as it might damage the assembly (e.g. I’m not sure what will happen when water is frozen in the o-ring glands - it might cause the design to fail when the ice expands).

I think we have had customers use the sensor in [liquid water in] freezing temperatures, so that might be ok.

I’m unsure whether @Marruger was using a Bar30 or Bar100 in their antarctic testing, but this (and the rest of their notes) may be worth a read:

@Marruger

Anyone operating in sub-zero conditions can take note that I would often store the unit in the water turned on, rather than on the ice as it was warmer (-2 compared to -20 C). I only had one situation with frozen props on a battery change, which freed themselves in short order once in the water. Each time I lifted the unit out of the water I would tilt it around to drain water from the props, and this worked fine. I had no issues with condensation and did nothing other than putting new desiccant bags in once prior to the trip.
