Position Control System (PCS)

  • The TRD Position Control System (PCS) is designed to control any 1.50" through 4" bore pneumatic TRD position feedback actuator. The system is a closed loop electronic controller using pneumatic technology that can accurately place and hold the actuator rod at any desired position with a fairly high degree of accuracy and force.
  • When combined with a low friction Position Feedback Cylinder (PFLF), the repeatability of the system can be achieved up to ± 0.004 of an inch at an average velocity of 6.50 inches per second and loads of 90 lbs.
  • When used in conjunction with a rod lock, the position feedback cylinder can hold position even with the loss of air pressure.
