Pressure Process Station (3501)
 
產品簡介
  The Pressure Process Station, Model 3501, consists of two air tanks, each having a 0.44-liters (2-gallon) capacity, which can be patch-connected individually, in series, or in parallel. Used individually, each tank, demonstrates a single capacity process with a single volume and minimal lag. Connected in parallel, the tanks demonstrate a single capacity process with dual volume. Connected in series, the tanks show a dual capacity process, both with interacting lag.
The process load consists of an exhaust assembly connected to a muffler. Needle valves at the tank connections and exhaust assembly permit the introduction of demand and supply disturbances and allow for varying degrees of restriction to all loop configurations, thereby providing a variety of process rates and responses. An I/P converter, electronic pressure transmitter, and diaphragm-actuated valve have all supply and signal lines terminated at quick-connect fittings on the main control panel. Mounted on the main panel are the microprocessor-based controller, strip chart recorder, 0-700 kPa (0-100 psi) pressure gauges, 0-2.4 l/s (0-5 SCFM) flowmeter, orifice assembly, and two alarm lamps.
