Hydraulically operated control equipment, e. g. on
- Construction and drilling vehicles
- Cranes and excavators
- Lifting devices and conveying equipment
- Ships and offshore facilities, etc.
are to an increasing extent controlled by electronic means nowa-days. This is the application range - in consideration of the extreme conditions of use - which the control transmitters ST2000 are especially designed for.
Corresponding to the lever displacement, they provide a direction dependent switch and control signal output for both axes x and y.
Other control commands can be initiated by actuating the control elements integrated in the grip handle of the control stick.
Wear-free and non-contacting inductive or magnetic systems are used as primary elements of the measuring system. An additional cost-effective option with resistance output is also available. They are available as uniaxial and dual axis transmitters.
The integrated electronic circuit provides for control purposes on its output per axis either a current or a voltage signal (analogue) and with CANopen interface (digital) respectively also redundant for security relevant applications according to IEC 61508 SIL (Safety Integrated Level) and ISO 13849 PL (Performance Level) respectively.
Transmission protocol according to user requirements.
For direct drive of hydraulic servo valves the inductive control system can also be equipped with an integrated power electronics with pulse-width-modulated output current up to 1000 mA.
