压力开关采用高精度、高稳定性能的压力传感器和变送电路,再经专用 CPU模块化信号处理技术,实现对介质压力信号的检测、显示、报警和控制信号输出。压力开关可以广泛用于石油、化工、冶金、电力、供水等领域中对各种气体、液体的表压、绝压的测量控制,是工业现场理想的智能化测控仪表
压力开关主要类别包括常开式和常闭式。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。
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。
2.压力开关主要敏感元件2.1波纹管
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,*大为40MPa(CB33)2.2膜片
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。
