5kN Servo pneumatic actuator





Servo Pneumatic Actuators - up to 5kN


The Si-Plan servo-pneumatic actuator is a versatile, tried and tested component.

Actuators are available incorporating the following characteristics:

  • Displacement travel up to 150mm.
  • Acceleration: up to 3.2 m/sec/sec.
  • Force from 10 to 5000 newtons.
  • Operating frequency: static to 25 Hz.
  • Typical unit weight: 10 kg.
  • Operating air pressure: 4 to 12 bar.
  • Typical air consumption at 1 Hz and 30 mm stroke (equal to tidal volume of 2.34 litres): 28.3 litres per minute at 6 bar.
  • Built-in load transducer; sensitivity 0.2 mV/N
  • Built-in displacement transducer; sensitivity 12.5mV/mm
  • High side load rejection.
  • Dimensions: diameter: 150mm; length: 310mm for the 60mm stroke unit; 490mm for the 150mm stroke unit.

Applications

Si-Plan's servo-pneumatic actuators are employed in rigs including:
  • Artificial limb testing machines.
  • Materials testing machines, delivering static loads up to 10kN.
  • Fatigue testing machines, delivering dynamic loads up to 8kN at 5Hz.
  • Hydraulic damper testing.

Advantages of servo-pneumatic air servo systems include:

  • high reliability (in excess of 100 million reversals without maintenance).
  • little or no heat generated.
  • low inertia.
  • inherent predictable stall thrusts.
  • very low lubrication requirements.
  • no fire risk.
  • able to run from workshop air supply with standard filtration, or bottled air.
  • EMC benign.
  • the static accuracy will normally be within 1% of full scale of the demand requirements.
