The PSW-190 cylindrical pressure switch has an epoxy-sealed electrical termination. This rugged design enables the switch to withstand harsh environments.
SPECIFICATIONS Switch: SPDT, 5 amps at 250 Vac or 30 Vdc gold clad silver contacts for loads down to 5 mA at 6 Vdc, 2 mA at 12 Vdc and 1 mA at 24 Vdc Operating Ambient Range: Buna-N construction: -20 to 75°C (-4 to167°F) FKM construction -20 to 80°C (-4 to 176°F) Media Temp: Buna-N construction: 70°C (158°F) FKM construction 120°C (248°F) Wetted Parts: Brass, O-ring and diaphragm Repeatability: PSW-191, 192, 195 and 196: ±1% PSW-193, 194, 197 and 198: ±1.5% Shock: Setpoint repeats after 50 g's 10 msec duration Vibration: Setpoint repeats after 10 g's, 5-500 cps Enclosure and Cover: Aluminum with irridite finish rated for 100 hr salt spray; potted and gasketed for outdoor use Pressure Connection: PSW-191, 192, 195 and 196: 1/8 NPT PSW-193, 194, 197 and 198: 1/4 NPT Weight: 128 g (4.5 oz)
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.
