Product questions
What does Murphy 05700386 measure and what is its range?
The 20DP-15 indicates differential pressure from 0 to 15 psi (approximately 0 to 103 kPa). It has a 2-inch dial and a diaphragm sensing element.
Can the 20DP-15 monitor filter restriction and trigger an alarm?
Yes. It is intended to indicate restriction in oil, fuel or water filters. Its adjustable contact can be used in a suitably designed alarm or equipment shutdown circuit.
How does the 05700386 switch contact work?
The gauge pointer completes a pilot-duty circuit when it touches the adjustable limit contact. The contact is grounded through the steel case. The manufacturer rates the adjustable contact at 2 A at 30 V AC/DC for pilot duty only.
Will Murphy 05700386 replace the gauge on my equipment?
Fitment cannot be confirmed from equipment type alone. Provide the equipment model and serial number and the existing gauge part number; verify the pressure range, connections and electrical requirements before ordering.
