The solenoid value was normally open (air could flow). When power was applied the solenoid closed the valve. The current blip was when the value reached the closed position and the solenoid suddenly stopped moving.wow.
What do you mean that the solenoid hit the closed position?
The coil doesn't have to saturate to close the poles, but it will likely be near saturation when the coil is at it's rated current.Oh I see, thanks.
By the way, in regular relays (ones with contacts), for the relay to change its state (meaning to change the location of the pole), the coil needs to saturate (become a short)?
I was wondering if its possilbe to determine the coil's value by the switching time thats specified in the spec.
For example, in my relay it is said that the maximal switching time is 15msec, and that the coil resistance is 25ohm (+- 5%), so can is it correct to say that:
L = 15msec * 25ohm = 0.375H ?
