Control Valve Electric Rotary Position Switch Transmitter Linear Steel Material

GE Masoneilan digital positioner satellite SVI Series Digital Valve Positioner with display and Hart Communication

Product Introduction

The 496 Series devices are used for indicating positions in the stroke of a control valve on which they are mounted. The detection can be either on-off, in which the housing is fitted with micro-switches or proximity detectors, or continuous, in which the housing is fitted with an opto-electronic unit. Both functions, on-off and continuous, can be combined. These devices may be mounted on rotary valves such as Camflex* II, MiniTork* II, or V-Max*, or on linear motion valves such as the series 21000 and 41005. The body and cover are made of epoxy-painted anodized aluminum. These devices can be explosion-proof and dust- and water-tight in accordance with ATEX 94/9/EC Directive. Some of them are intrinsically safe. (See the following pages for details.) The absence of mechanical contact in the proximity detectors and the opto-electronic position transmitters produces • almost complete insensitivity to vibrations and electrical interference, • very low operating friction, • virtually infinite operating life.
