MEASUREMENT SOLUTIONS BARTON 202E, 202N, 242E and J8A Chart Recorders Sensia’s BARTON® chart recorders are the industry standard for accurate, reliable measurement and recording of pressure, differential pressure and temperature in a variety of applications. Differential pressure models, like the 202E and 202N, utilize the BARTON rupture-proof bellows DPU as the actuating unit, featuring over-range protection and pulsation dampening. COMMON COMPONENTS + Case – The case is made of rugged, lightweight die-cast aluminum that features a built-in rainshield. It is finished in polyurethane electrostatic powder paint that has a high resistance to weathering, scratches, and industrial fumes. An aircraft-type door hinge (made of 302 SST) provides excellent resistance to salt spray and H2S. The seal between the door and the case is made of neoprene, a material that is non-absorbant and resistant to oils and most solvents. + Chart Drive – Chart drives are available in battery and spring-wound versions with a wide variety of rotation speeds. All chart drives have a simple, positive chart lock hub and are interchangeable. + NUFLO™ Charts – The charts are made from wood-free paper – a special, low-shrinkage, high quality product that eliminates eccentric and elliptical errors. Charts are shrink-wrapped to help maintain the factory default size until the package is opened by the user. Once a box of charts is opened, it can be stored in the supplied, plastic, resealable storage bag. + Recording Mechanism – All parts are stainless steel for long life. The pen mount is exceptionally rugged and pen shafts are fitted with ball pivots to minimize friction. All links are adjustable, with micrometer adjustments for accurate calibration. All adjustments have screwdriver slots to simplify calibration. Disposable pens are standard. + Thermal Systems – The systems consist of a bourdon tube, a capillary with stainless steel armor and a bulb with a bendable extension. All parts are stainless steel. Systems are available in Class I liquid fill with a 3/8” OD bulb. Temperature ranges for each design are listed below. A thermal system must have a span of more than 50° F (27° C) and the high temperature limit must be greater than 95° F (35° C). • Class IB ( liquid environmental fill – case compensated) 14° F to 300° F (-20° C to 150° C) • Class IA (liquid hydrocarbon, fully compensated) – temperature range varies with fill material – Ethyl-benzene: -125° F to 350° F (-87° C to 177° C) – Consult factory for other fill materials and ranges • Class IB (liquid hydrocarbon, case compensated) – temperature range varies with fill material – Ethyl-benzene: -125° F to 350° F (-87° C to 177° C) – Consult factory for other fill materials and ranges • Uncertainty ± 1.0% of Full Scale • Hardware Capillary standard length is 10’. Case compensated available up to 20’. Lengths longer than 20’ feet must be fully compensated + Pressure Elements – Used in Models 202E, 242E, and J8A, genuine BARTON pressure elements are a precision wound helical-type, available in a variety of pressure ranges from 0 to 25 psi (1.72 bar), up to 0 to 30,000 psi (2,068 bar). The Model 202N uses a Monel K500 pressure element in ranges from 0 to 250 psi (17 bar), up to 0 to 6,000 psi (414 bar). Connections available in 1/4” NPT for ranges up to 10,000 psi (689 bar). Ranges greater than 10,000 psi (689 bar) utilize an Aminco 9

BARTON Chart Recorders MODELS 202E (DP) The 202E is a 12” chart recorder, widely used in gas transmission and in production fields because of its high accuracy recording mechanism, even under extreme variations in flowing pressure and ambient temperatures. MODEL 202N (DP) (NACE) The 202N is a 12” chart recorder designed to measure flow, static pressure and temperature in sour gas applications. The 202N meets all NACE requirements for H2S environments, per MR-01-75 (2009) and ISO 15156:2009. The 202E is available in 1 to 4 pen configurations (DP+ 3 additional pens). The additional pens can...
