Registrador de Presión
BARTON® Model 202E Flow Recorder
BARTON chart recorders are the industry standard for accurate, reliable measurement and recording of
pressure differential pressure and temperature pressure, pressure, in a wide variety of applications. In addition, DP models
utilize rupture?proof bellows DPU as the actuating unit — with features like overrange protection and
pulsation dampening (on some models).
The 202E is a 12-inch chart recorder that has been widely used in gas transmission and distribution fields
– accurate calibration, even under extreme variations in static pressure and ambient temperatures. The
202E is available in 1 to 4 pen configurations (DP+3 additional pens). The additional pens can be used to
record temperature and supplemental pressure data. The unit is actuated by a BARTON Model 199 DPU,
with standard and NACE units available (up to 6,000 PSI/414 bar SWP) — see DPU bulletin #21700 for
details. Static pressure and temperature pens are actuated by precision wound elements.
