Solenoid actuated sampler |
摘要 |
A fluid pipeline sampler adapted for in-line or by-pass type sampling includes a body having a passage therethrough and a fluid outlet. The sampler is actuated by a pulling-type solenoid in response to an actuating signal. The solenoid shaft is coupled to a yoke that includes a piston mounted on the end opposite the solenoid shaft. The yoke surrounds a valved body extension, and along with the piston and body extension define a sample cylinder. The body extension has a bore that is in fluid communication with the fluid outlet of the main body and the sample cylinder. Initial displacement of the yoke positively causes the piston to trap a sample of known volume within the cylinder. Further displacement injects the trapped sample into the body extension bore that then travels into a sample collector.
