Gefran Solution for Mobile Hydraulics

         

Gefran offers solutions that perform specific functions in the field of Mobile Hydraulics. Gefran linear displacement transducers, displacement sensors, and indicators are ideal for a wide variety of applications: from steering systems through to stability control and to suspensions.

Flexibility
Gefran displacement transducers are based on potentiometric and magnetostrictive technology and provide various performance levels according to application requirements. All of the products:
    • Include a high protection level (IP67 - IP68)
    • Resist high pressures (350-700 bar for cylinder models)
    • Heavy-duty, ready to install in harsh environments or outdoors, and include high resistance to vibration and shock
    • Powered with low voltage 10...30 Vcc

Installation of a linear displacement transducer in hydraulic cylinders: Gefran offers 3 solutions

 Display
The use of simple displays or graphic terminals allows integration with more advanced control systems.

 Checking pressure in hydraulic circuit
TK transmitters monitor oil pressure in the hydraulic circuit for checking vehicle load and stability.

 Roll-over prevention
The synergy of displacement transducers inside (IC, RK) or outside (PC67, PMA) the cylinder with pressure transmitters (TK) guarantees total working control of the bucket to maintain tilt even during load handling. Load control guarantees greater stability and safety.

 Steering system
RK displacement transducers are ideal for installation inside single-action cylinders normally used with hydrostatic steering units. The sensor is designed to guarantee resistance against vibration and shock typical in this application.

 Stability control
Suspension cylinders are an integral part of a sophisticated, electronically controlled system that guarantees vehicle flexibility and stability based on applied weights, work load, and ground conditions. RK and IC transducers are designed to provide precise and positive control in this type of application.

 Load handling control
The use of increasingly complex control systems to check vehicle position and movement of each joint requires the use of transducers with advanced interfaces, such as CANopen, available on all Gefran magnetostrictive transducers.
