Description for Fisher 4194H Differential Pressure Indicating Controller

Features Easy Maintenance—Simple design of the controller allows fast, easy maintenance and minimal spare parts inventory. Easy Adjustment—Adjustments of set point and zero and span of the process pointer, and switching between direct and reverse action are accomplished quickly and without special tools. Also, the set point and proportional band can be adjusted with no interaction between the two adjustments.Highly Visible Display—Two red pointers on a 114 mm (4.50 inch) long white?on?black scale show differential pressure and deviation from set point at a glance. Two other gauges monitor supply and output pressures.Low Air/Gas Consumption—The relay and nozzle design reduces the steady-state consumption rate to as low as 0.07 m3/hr (2.5 scfh); less than the 6 scfh requirement set for the oil and gas industry by the US Environmental Protection Agency (New Source Performance Standards Subpart OOOO, EPA?HQ?QAR?2010-0505).Corrosion Resistant—Thermoplastic housing withstands a broad range of corrosive environments. Internal constructions are available to resist a corrosive supply pressure media.
