Product Name: Fisher 4194H Differential Pressure Indicating Controller Product Brand: Fisher Product Code: 4194H Product Artikel: 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.
