Chart Recorder, Potentiometric Circular

Elar Controls & Systems offers Series 3000 electronic potentiometric null balance circular chart recorders. These are robust devices and give dust-proof protection to the circuitry inside. The servo drive is IC designed and small variation produces instantaneous variation in the recording. These recorders come in three models - Major, Midi and Mini. Dual pen recorders are available in Major and Midi models. Also, digital scales are offered in these models only. All recorders accept sensors, voltages and currents. Other parameters such as pressure, humidity and flow are through suitable transducers. Control actions are provided with powerless changeover contacts at output. The digital readout gives instant reading while the recording is progress. Both analogue and digital circuits are independent of each other. The Major models utilize 255 mm charts whilst Midi and Mini models utilize 155 mm charts. Continuous recording is done by disposable pens. It has a wide field of application mainly where authenticated logging of process and batch process certification is mandatory.
