| 产品简介： | |||
| SOR®Pressure Switches | |||
| are rugged field-mounted instruments. The | |||
| pressure sensing element of the SOR pressure | |||
| switch is a force-balance, piston-actuated | |||
| assembly. The sensing element is sealed by a | |||
| flexible diaphragm and a static o-ring. A wide | |||
| selecion of wetted parts materials for media | |||
| compatibility and containment are available. A | |||
| metal diaphragm may be welded to the | |||
| pressure port for certain applications, thereby | |||
| eliminating the o-ring. | |||
