Versatility is a design attribute. Thus, four independent, field-adjustable, solid-state pressure switches are available as part of Barksdale's PS4G microprocessor-based open-loop pressure controller. Eight different models accommodate pressure ranges from 0-15 psi to 0-9,000 psi. An LCD display gives operating conditions or settings. The latter are adjustable by a large membrane keypad. Each switch is set to activate on rising or falling values by a dedicated key. An internal dip switch and simple key pad command both furnish tamper prevention. A differential-pressure model handles input from two transducers, as in monitoring flows before and after filters. A built-in memory stores set points, and high and low readings during power outages. Data may also be recorded via a PC serial port. Barksdale: Product Code 4309.
