NASON压力开关技术分析,NASON压力开关主要类别包括常开式和常闭式。美国NASON压力开关的主要特点是: 1、采用英制管螺纹快速接头或铜管焊接式安装结构,安装灵活,使用方便,无需特殊的安装固定。 2、插片式导线式连接方可供用户任意选定。 3、密封式不锈钢感应器安全可靠。 4、压力范围内可根据用户任意选定的压力值进行制造。 美国NASON低压开关MM系列的特性: 长寿命橡胶隔膜,高质量快动作开关 工厂预设,可在大范围的配置 经济,气动和九头蛇 NASON压力开关是一种简单的压力控制装置,当被测压力达到额定值时,NASON压力开关可发出警报或控制信号。纳森压力开关的工作原理是:当被测压力超过额定值时,弹性元件的自由端产生位移,直接或经过比较后推动开关元件,改变开关元件的通断状态,达到控制被测压力的目的。 NASON液压和气动压力开关,Nason’s complete line of pressure switches offers design engineers a choice of low to high pressure switch models ranging from 2 PSI to 7500 PSI. Models are available for both pneumatic and hydraulic applications. All of Nason’s pressure switches use a snap-action electrical device activated by a precise, long-life elastomer diaphragm or piston offering a precise and repeatable design.NASON压力开关技术分析 The snap-action design will maintain its state with contacts either open or closed, until a precise set point is reached when it will snap over center to a new state. It will remain in that state until a distinct change towards its original setting is sensed, at which time it will snap back to its original state. The design’s snap action feature prevents contact intermittency near its switch point, which is common in creepers. As system pressures fluctuate, our switches inherent differential prevents searching. Nason uses only the highest quality snap action switches. These switches and Nason’s are UL, CSA, and military approved. NASON压力开关是与电器开关相结合的装置,当到达预先设定的流体压力时,开关接点动作。主要应用于电厂、石化、冶金行业等工业设备上输出报警或控制信号,在工业领域中有着重要的用途,能预防生产工程中重要装置的损坏,避免了重大生产事故地发生。 NASON压力开关主要敏感元件2.1波纹管 纳森压力开关特点:耐久性及耐振性较波登管好,接断差可调范围大,主要材质有不锈钢、磷青铜等,价格相对较高,但可测压力范围较小,zui大为40MPa(CB33)2.2膜片 纳森压力开关特点:具有出色的耐腐蚀性,主要材质有NBR、氟橡胶等,如CS、CL系列等均采用此类敏感元件。压力开关快易优自动化选型有收录。NASON压力开关技术分析 |
