Temperature Recorders

Product Description

Circular Chart Temperature Recorders are technically proven instruments for the Performance, ruggedness, durability & accuracy and are used for recording temperature variations in any process industry.
Working Principle

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 anticlockwise 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.

YANTRIKA® Pressure / Temperature Recorders can be manufactured with single or double pen arrangements and are driven either by a Mechanical /Electrical Chart Drive or Quartz Drive. The Mechanical Chart Drive is recommended for hazardous applications. Every pressure recorder is calibrated to ensure the guaranteed accuracy of ± 1percentage.
