YANTRIKA Circular Chart Pressure /Temperature Recorders are technically proven instruments for the performance, ruggedness, durability & accuracy and are used for recording pressure / temperature variations in any process industry.
Circular Chart Recorder
Working Principle
Pressure : Rise in pressure deflects the sensing element which is connected by mechanical linkage to the Pen arm, which records the Pressure on suitably calibrated chart. This chart will be rotated anti-clockwise with the help of chart drive at a constant speed. This helps us to find out pressure variations at any point of the time period.
Temperature : Rise in temperature causes mercury in the capillary to expand which is connected by mechanical linkage to the Pen arm, which records the temperature on suitably calibrated chart. This chart will be rotated anti- clockwise with the help of chart drive at a constant speed. This helps us to find out temperature variations at any point of the time period.
