BARTON Chart Recorders

Cameron’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. In addition, DP models utilize BARTON rupture-proof
bellows DPU as the actuating unit – and DP models have features like overrange
protection and pulsation dampening (on some models).

Models 202E (DP)
The 202E is a 12” chart recorder that has been used widely in
gas transmission and distribution fields because of its 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 4500 psi/310 bar SWP) – see DPU
bulletin #21700 for details. Static pressure and temperature pens
are actuated by precision wound elements (see page 1).

Model 242E (Temperature/Pressure)
The 242E is a 12” chart temperature and pressure recorder
designed for general pressure applications.
