Intrinsically Safe Pressure Pilots Control
Series 90
For more than 40 years, Danfoss has been developing state-of-the-art components and systems for mobile machinery used in off -highway operations around the world. We have become a preferred supplier by offering the best of what really matters: The hardware inside your vehicle application.
This line of Intrinsically Safe Pressure Control Pilots receives a low current input signal from a variety of machine controllers and converts the current signal into a proportional differential pressure signal suitable to control larger hydraulic equipment in hazardous locations. The intrinsically safe controls can be added to a Series 90 pump as a standard option or purchased separately.
Danfoss offers five different models of intrinsically safe pressure control pilots to accommodate a variety of standard industrial process controllers. Various combinations of hydraulic nozzle sizes and coil resistances yields a relationship between electrical current (input) and hydraulic differential pressure (output).
Features
•Standard manual override
•Withstands mobile equipment vibration and shock conditions
•Controls both pilot-operated pumps/ motors and main spool valves
•Standard MS-style connector
•Self-contained pressure feedback
•Constant scale factor with varying pilot pressure
•Can be used in either closed loop or open loop systems
