Rotary actuators

Ken #3463 Drew... You are one lucky guy! During one of my rare lucid moments I found 4 of the rotary actuators I mentioned yesterday. These would be very easily modified by the addition of a vane (or flag) to cover the opening of your evap box during the initial heating of the material. I would position the flag in a fail-safe manner i.e. with the opening covered unless the actuator is powered up. I believe these are 24VAC movements but should be fairly easy to figure out. If you have a variable power supply (XMS?) you could ramp up the voltage until they move then measure the voltage and add a bit for reliability sake. I can't remember if the XMS had 120vac outputs for the switched devices or not but a doorbell transformer (or voltage dropping resistor) might just be the ticket if so. Not sure about how they would behave in a vacuum re: outgassing, oils etc. They seem to be "dry" but any mechanism is likely to outgass for a while in vacuum. Already addressed in a box and will be on your way this weekend. Ken
Aurigema, Andrew N. (KSC-ASRC-474)[ASRC AEROSPACE] #3464 开云体育 Ken, ? You da man.? The XMS 1 does indeed have switched 120 ( two of them actually )? so I will get creative and figure out something.? I polished out the mirror that I buggered up and now it is ready to be re-coated.? I will wait for your gracious gift to arrive and rig up some kind of controllable flag of some kind. ??I can degrease and re-lubricate with krytox so outgassing is not an issue.? ? ? Thanks again.? ?
