SIGMA压力传感器72系列72KS25S介绍
SIGMA Valves在四十多年前开始生产专门用于石油和天然气行业的不锈钢气动和液压控制阀。SIGMA Valves起源于专门为海上环境中的安全系统自动化而设计的阀门，而不是用于石油/天然气行业的工业阀门。与小型工业型阀门相比，这些阀门具有更强大的设计特性和可靠性。

SIGMA压力传感器72系列介绍
72KS系列压力传感器是两位置，三通模块和泄放（通用）压力监测流量管线先导。可以将其连接为高（上升/上升）或低（下降/下降）压力传感设备。在高压安全（PSH）应用中，设计的先导阀会在超过高压设置时失去仪表供应输出。在低压安全（PSL）操作模式下使用，只要超过低压设置，压力传感器就会获得仪器供应的输出。
当检测到异常的高或低过程压力时，可使用三通截止阀和排气先导阀来关闭安全阀并保护设施。在其他应用中，它们用于启动/停止特定压力范围限制内的控制序列。
The 72KS Series Pressure Sensors are a two position, three-way block and bleed (universally ported) pressure monitoring Flow Line Pilot. It can be connected to respond as either a High (rising/ increasing) or Low (falling/decreasing) pressure sensing device. In the Pressure Safety High (PSH) application, the Pilot is designed to lose instrument supply output whenever the high-pressure setting is exceeded. Employed in the Pressure Safety Low(PSL) mode of operation, the pressure sensor will gain instrument supply output whenever the low-pressure setting is surpassed.
Three-way Block & Bleed Pilots are used to initiate safety valve closure and safeguard facilities upon detection of either an abnormal high or low process pressure. In other applications, they are used to start/stop control sequences within particular pressure range limits.
