The Series SC1090 Thermocouple Limit/Alarm Switch Modules are on-off or limit switches with selectable process signal. Input type, scale range, output action, and output type are all selectable by the user in the field. All selections are made through easily accessible switches without the need to open the product. Each unit has two form C (SPDT) relays which can operate independently, or be logically connected to operate as a DPDT output. A two color LED indicator indicates the status of each output relay.These units mount easily on a standard 35 mm DIN rail. Low Voltage (SCL XXXX) units are also available.
THE SERIES WE07 incorporates a V-port ball valve for impressive flow rates with minimal pressure drop. Quarter turn control ball valves are compact, lighter weight and much less expensive than comparable sized globe valves and segmented control valves. They also offer bubble tight shut off with zero leakage and can withstand high pressure drops. The 60° and 90° balls offer an equal percentage flow characteristic. W. E. Anderson’s V-port ball valves have been designed to offer maximum flow characteristics that are substantially higher than comparably sized globe valves. The natural flow pattern of ball valves increases flow rates and in many applications valves smaller than pipeline size can be used.Actuators are direct mounted creating a compact assembly for tight spaces. Limit switches can be mounted directly to the valves allowing for remote position indication.The Series WE07 can be configured with an electric or pneumatic actuator. Electric actuators are available in weatherproof or explosion-proof, a variety of supply voltages and Two-position modulating control.Two-position actuators use the supply voltage to drive the valve open or close, while the modulating actuator accepts a 4 to 20 mA input for valve positioning. Actuators feature thermal overload protection and a permanently lubricated gear train.The pneumatic double acting actuator uses an air supply to drive the valve open and closed. The actuator has two supply ports with one driving the valve open and the other driving the valve closed. Spring return pneumatic actuators use the air supply to open the valve and internally loaded springs return the valve to the closed position. Also available is the SV3 solenoid valve to electrically switch the air supply pressure between the air supply ports for opening and closing the valve. Actuators are constructed of anodized and epoxy coated aluminum for years of corrosion free service.
产品介绍:STAPS蒸汽疏水阀监测系统(无线)斯派莎克STAPS蒸汽疏水阀无线监测系统,可通过简易的非侵入式安装,来实现精确的无线检测和报告,以帮助您提供蒸汽系统的性能。您只需要在蒸汽疏水阀上游管道上安装检测头,它可以通过“听”疏水阀在运行中的声音信号来检测。这个声音信号将被分类, 并通过2.4GHz无线网络传递至上位机,并由斯派莎克的监测管理系统来判断疏水阀的状态,并精确计算疏水阀泄漏时的蒸汽损失。蒸汽疏水阀监测系统(有线)斯派莎克同时可以提供有线的Spiratec蒸汽疏水阀检测系统,其主要元件是一个安装在疏水阀入口前端可连接探针的感应器。当感应器和指示器的探针接头连通后,感应器便给出一个明确的“良好”或“失效”信号。感应器可永久性地连接到工厂的维护管理系统。除此之外,斯派莎克还提供UP100超声波疏水阀检测仪。UP100可给出可视的和可听的超声波频率指示,作为分析蒸汽疏水阀工作状态的诊断工具,也可用来检测蒸汽和压缩空气系统的泄漏。
