Pressure & Vacuum Switch
Brand: Cameron
Pressure switches are rugged, field-mounted instruments. The pressure sensing element of the 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 selection 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. Features and Benefits:
- Robust construction
- Instrument quality
- Snap-action electrical switching
- Field adjustable
- Cost effective
- Shock/vibration
- Built-in quality
