Barksdale 600 Series Transducers

Why Use Barksdale Transducers
Mobile Hydraulics:
Monitoring and Controlling Excavators


Hydraulic excavators are used in a wide range of applications, including road construction, laying pipelines and mining. The excavator is a versatile piece of equipment that can be fitted with attachments such as tilt-rotators, breakers, grapplers and augers, allowing it to be used in other applications besides digging. The entire system relies on the transfer of hydraulic fluid acting upon cylinders for movement and function. Pressure transducers serve as a critical component in monitoring and controlling the hydraulic system. In this application, the Series 600 transducer is used to sense hydraulic oil pressure in the pilot system (the system that allows the pilot to control the excavator) and the main hydraulic pump. System pressure can vary up to 6,000psi. Typically, a 4-20mA analog signal is sent to an on-board controller based on the system pilot pressure. The transducer is ideal to control the displacement of the main pump and hydraulic flow to the directional control valves that have the ability to control several excavation functions.

Transducers also offer advanced feedback for engine and tool control, as well as monitoring pressures in the drive train (clutch, brakes, or engine). The lower cost, rugged, reliable and compact size requirements make the Series 600 Transducer a good fit for these applications.

Product Reliability  Ceramic sensor  Monolithic structure ensures excellent resistance to shock/vibration and water hammer.
Thermal Stability  Thermal Stability 0.06% over entire operating range -40 to 185F  Minimal thermal drift is a superior benefit of ceramic sensors. Tolerates temperature shock without compromising quality.
Accuracy  0.5% accuracy  Built for todays equipment that require greater accuracy than mechanical switches at a lower cost.

Did you know...
that the Series 600 is approved for both UL508, UL 61010-1 and CSA 22.2 No. 61010-1? UL508 is specifically listed for Industrial Control Equipment, while UL61010-1 is listed for Electrical Equipment for Measurement, Control, and Laboratory Use. The UL 61010-1 (for the United States market) and CSA 22.2 No. 61010-1 (for the Canadian market) is part of IEC 61010 that specifies general safety requirements for electrical equipment intended for professional, industrial process, and educational use (any of which may incorporate computing devices).
