Pressure gauge with alarm

[blown motor]

The situation: Our corn planter has an airbag on each row unit that is responsible for down pressure to make sure that it penetrates the ground properly. All 16 rows are on a common system so any leak in the system effects all rows. This spring one of the airbags became dislodged and got punctured. Luckily we caught it before we went to far but we aren't always looking at the gauge. Is there a gauge with an adjustable alarm setting that we can install so if the pressure drops below a certain point the alarm goes off to warn us?

Here are some examples of what looks like would work for what you want.

Seed planting & harvesting is going robotic in the near future.

Company near me in Sunnyvale is already underway with planting & harvesting equipment.

Yup, soon I'll just have to watch from my e-body on the side of the road and take the cheque to the bank.
