| 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. |
