Контроллер дифференциального давления Fisher™ 4194

Simple design of the controller allows fast, easy maintenance and minimal spare parts inventory.;Adjusting the set point and the zero and span of the process pointer and switching between direct and reverse action are accomplished quickly and without special tools.;Simple design and low mass of internal parts allow the controller to withstand vibration encountered in most plant environments.;Relay and nozzle design reduces steady-state air consumption to as low as 0.09 normal m3/hr (5 scfh).;Tough plastic housing resists corrosive environments. Internal constructions are available to resist a corrosive supply pressure media.;The controller can mount directly on the actuator or it can mount on a pipestand, on a wall, or in a panel.;Two red pointers on a 114 mm (4 1/2 in) long white-on-black scale show differential pressure and deviation from set point at a glance. Two other gauges monitor supply and output pressures.
