Can a 9012GAR5 be used on water systems?
9012 Pressure Switches
Yes, all components are compatible with water systems. However, salt water may attack standard flange material and may work best with 9013F Form Q. It is important to note that these switches are control rated devices. An interposing starter, or contactor must be used for switching a pump motor . Low level signals to PLCs or computers requires the use of an interposing low level switching relay.
