Chart Recorders & Controllers

Originally developed in the early 1920s, Barton Chart Recorders differential pressure units feature a welded bellows assembly that increases accuracy while dramatically reducing the effects of wear. To facilitate quick and easy repairs all DPU based instruments are supported with pre-calibrated exchange or repaired sub-module bellows assemblies. Chart Recorders are available in a number of formats and sizes – with temperature to 260 deg C and pressure to 30,000 PSI. Chart Drives are available in battery and spring-wound versions with a wide variety of chart speeds. All chart drives, with a simple positive chart lock hub, are interchangeable. 12″ versions are the 242E and 202E/N with the 8″ J8A a smaller option
