注意事项
压力开关广泛应用于家用、商用、汽车制冷系统的高、低压力保护控制，蒸汽工况和发电站;蓄能器,接收器,闪蒸罐,分离器,洗涤器,炼油装置。也可适用于各种设备工具的高、低压力保护控制。但在压力开关的选择中，须注意以下几点：
1.防爆的必要性：防爆形式分为隔爆型和本安型。
2.是否需要带指示：根据客户指示。
3. 接点数量：一接点（一个输出）或两接点（两个输出）。
4.设定值和压力范围的确定：推荐设定范围在压力范围的30%—65%之间，可设定范围为压力范围的15%—90%之间。
5.接断差的形式：可调式或固定式。
6.是否有脉动：如果压力有脉动或振动，需要带节流阀用以抑制脉动压力对仪表的损伤。

7.带隔膜的场合：测定腐蚀性、高黏度或温度过高时，需要选用带隔膜。
