Description
The M-100X adjustable flow switch is an extremely sensitive and explosion proof flow switch. It has been engineered to monitor vital sample flow parameters for instrumentation in process control and inert blanket gases. It is used as an auxiliary alarm monitor for flow meters and is suited for applications when installed on a bypass for determination of filter plugging. Available in 1/8" FNPT and 1/4" sizes with Stainless Steel as material options, the M-100X Flow Switch offers a water flow range of 17-2,000 ml/min and an air flow range of 400-65,000 sscm.
When there is no flow the free magnetic piston rests on the bottom of the bore. Process changes in the flow, relative to the variable orifice adjustment initiates the movement of the piston which is restored to its original position when there is a loss of flow. The movement of the piston actuates a sensitive reed switch which can be positioned to indicate a normally open or closed circuit, depending on the specific requirement. A counter-clockwise adjustment of the adjusting screw allows more flow through the bypass, effectively rendering a less sensitive flow switch. A clockwise adjustment of the adjusting screw reduces the bypass flow, redirecting the flow path to the main bore for a more sensitive flow switch.
Applications
- Gas and liquid analyzers
- Atmosphere furnaces
