Questions

Question

Will the MVS series vacuum switch work if they are in the box with the vacuum. I need to signal when the vacuum in the box, in which the switch is placed reaches a level. The electrical connections are through a hermetic connector on the box.

Answer

No, the MVS needs to be mounted externally to the vacuum in a reference area or an area open to the atmosphere and connected to the vacuum source via appropriate process tubing depending on the model.
