[dsg-hallb_gas] ALERT DC Gas Pressure Sensor

[Patrick Achenbach]

Thank you so much, Brian.
With this lead time we can have it installed before the start of the run.

Since there seems to be some questions with the existing pressure sensors I've gone ahead and submitted a PR for three of these (0 - 1.6 Bar Absolute) sensors:

The price went up a few dollars, but luckily lead time is down to 10 days now.

Since they want to hold it at an absolute pressure we should eventually switch to a sensor that outputs in absolute rather than a gauge one.

Naturally there isn’t one that has a great range for what they want. 0-15 psia is too low, the next size up is 0-30 psia. I think the 0-1.6 Bar Absolute one will have to make due.

They are $172.95 ea and have a 20 day lead time.

For now we’ll just have to use the existing gauge sensors.
