Within the agricultural industry, Murphy controls and instruments are justly famous for their reliablity and long life. Whether it's our latest displays and engine controllers, or traditional Swichgage® devices and irrigation pump diagnostic centres, Murphy equipment is designed to operate time and time again in all weathers and conditions.

Murphy equipment provides control, monitoring and protection for a range of diesel-driven applications: tractors, specialist farm vehicles, PTO devices and pumping. Murphy hose-reel and drip irrigation pump controls are distributed through a network of specialist distributors, each of which has has in-depth experience of irrigation and pumping systems, and has received training in Murphy products.

Displays and Controls for ECU/CAN-based vehicles and equipment
These display and controls are compatible with the CAN SAE J1939 communication system, as used in virtually all the latest industrial diesel engines meeting Tier4/Stage IV exhaust emission regulations; many can also be configured for other CAN-based systems, or non-ECU/CAN engines. All are built to last, with class-leading environmental protection, operating temperature and vibration/shock specs, allowing use both inside and outside the cab:
	PowerView® Configurable Displays. Colour and monochrome displays, freely configurable to your machine and application requirements.
	PowerCore® Controllers and Panels Configurable control modules and full panel/harness solutions for engine-driven stationary or trailer-mounted equipment: pumps, compressors, shredders/chippers or power packs.
	CAN I/O modules - fully sealed devices for seamless integration of sensors, switches, actuators and drives into CAN-based engine and vehicle display and control systems.
