I am unsure if this will work for my application. I need a switch that can handle 3000 psi and will close contacts when pressure drops to 200 psi.

Thanks for your question. The PSW-194 will handle the range and you can set the set-point to trigger anywhere between 180 to 3000 psi, the dead band is 50 to 400 but is NOT adjustable - so it will open and close at any psi to maintain the set-point. Our Tech Support agent has also emailed you to provide further assistance. Please email us back anytime if you have any more questions.
