  • suited for test tasks with long strokes
  • as single-rod or double-rod servo cylinders
  • with integrated position transducer
  • low dead weight
  • optional mounting plate for control valve

Sensor technology and valves for servo hydraulic actuators
Perfect for dynamic industry and test tasks

For the necessary sensitivity, Hänchen offers convenient sensor technology components and valves – all for highly dynamic, precise drives with high energy density.

To operate the drive in an Industry 4.0 environment, sensors can also provide data for condition monitoring:
• Pressure transducers in the chambers analyse the friction behaviour
• Temperature and colour sensors provide information on the condition of the fluid
• Online particle counters indicate the degree of contamination of the system
• Flow sensors on the functional oil channel indicate the need for a seal change

Force transducer
Force transducers use strain-gauge or piezo-technology and measure the retracting and extending forces of the hydraulic cylinder. They are installed directly on the piston rod and measure the load on the piston rod statically or dynamically. Force transducers are used e.g. for monitoring or controlling the cylinder force.
Load cell work on strain gauges or piezo technology and measure the tensile and compressive forces of the hydraulic cylinder
Valves
Control valves regulate the flow rate in proportion to the electrical select signal. Depending on the application case, valves with hydraulic pilot control or directly proportional solenoidcontrolled valves are used. Valves with zero overlap of the control edges are especially suitable for hydraulic control tasks.
Proportional valves for Hänchen servoacturators
Proximity switch
Pressure-resistant inductive proximity switches detect the end positions of the stroke in the hydraulic cylinder – wear-free and without contact. The signal is used to check or control the hydraulic cylinder. Hydraulic cylinders with proximity switches also feature adjustable cushioning.
Pressure resistant inductive proximity switch detect the end positions of the stroke in the hydraulic cylinder contactless and wear-free.
Position transducers
Position transducers show the position of the piston rod electronically. An analogue or digital travel signal can be generated using the stroke. This can be used e.g. as an actual-signal in the position control circuit, or for monitoring position or speed limits. A position transducer can be integrated in the cylinder, making a compact, mechanically protected system.

Suitability of cylinder series according to frequency range

The required dynamics of the drive determine the cylinder's type of effect. When fast control valves are used, even single-rod cylinders achieve a high profile quality at high frequencies.

The limit values shown in the diagram are intended as guide values for your design. They depend on various operating conditions – we can help you make the right choice

Which actuator series is suitable for which frequency range

Servo cylinder configurations
Sealing and guiding systems

The sealing system in the cover and on the piston is the heart of a hydraulic cylinder and determines the possible applications. With these you determine the sensitivity of the servo cylinder movement, the minimum amplitudes which can be travelled and the effect of side loads. You can also choose low-wear sealing systems.

We recommend using the synthetic guide Servoslide® or PTFE wear rings as a guiding system in the cover for servo cylinders that operate in an oscillating manner.

Here you can learn more about the cover and piston equipment in the hydraulic cylinder.

** When pivot mounted, the pressure is limited to 120 bar.

F1 = Compressive force while the cylinder is extended | F2 = Compressive force while the cylinder is retracted
With double-rod cylinders, retraction and extension corresponds to the value F2.
