Diaphragm A Ɛyɛ Adwuma

Actuator Diaphragm no yɛ tumi nsakraeɛ fã titire a ɛwɔ mframa mu diaphragm actuator no mu. Ne dwumadie titire ne sɛ ɛbɛdane mframa a wɔahyɛ no nhyɛsoɔ a ɛba no mu no akɔ mfiri a ɛtu kɔ baabi foforɔ, na ɛnam so ama terminal control components te sɛ valves ne baffles no ayɛ adwuma, na awieeɛ koraa no wanya nhyehyɛeɛ pɔtee a ɛfa nsuo no nsuo a ɛsen, nhyɛsoɔ anaa nsuo dodoɔ (nsuo, gas, nsuo a ɛyɛ hyew) ho. Ɛyɛ nkitahodi titiriw a ɛka "control signals" ne "mechanical actions" bom wɔ process control (te sɛ petrochemicals, tumi, ne nsuo a wɔde yɛ adwuma) mu.

Sɛnea actuator diaphragm no yɛ adwuma no nya ahotoso a ɛwɔ control loop no nyinaa so nkɛntɛnso tẽẽ. Nsɛnkyerɛnne titiriw bi ne:
