How is the piston position detected in a Conforti hydraulic servo cylinder?

Conforti hydraulic servo cylinders are equipped with a high precision linear position transducer based on magnetostrictive technology. The magnetostrictive transducer operates without physical contact, using a magnetic field to determine the piston position. This technology eliminates mechanical wear and ensures long service life of the measuring system. The transducer provides an analogue output signal in current or voltage, or a digital signal in SSI, CANbus, DeviceNET, Profibus, EtherCAT®, EtherNet/IP™, PROFINET, or POWERLINK.

What are the advantages of using a Conforti hydraulic servo cylinder with transducer?

Conforti hydraulic servo cylinders are designed for applications requiring high precision in position control. The transducer continuously provides an absolute position signal, with no need for homing at power-up, and with very high resolution. The delicate external parts of the transducer are protected by a removable steel cover, ensuring protection against accidental impacts during transport, installation and operation. Thanks to the integrated CETOP plates, ISO 4410 valves and servo valves can be mounted directly on the cylinder body, reducing the oil volume between the valve and the actuator and facilitating closed-loop position control.

How can I select the most suitable Conforti hydraulic servo cylinder?

The configurator can assist you in selecting and technically validating the most suitable Conforti hydraulic servo cylinder for your application. You can choose from tie-rod ISO 6020/2 servo cylinders, counterflange ISO 6020/2 servo cylinders, or ISO 6022 servo cylinders. The configurator will guide you through cylinder sizing and the selection of the many available options in terms of features, materials, accessories, and more.
