Mercury-in-steel ATG Series 2001
These
Temp. Gauges Deploy Mercury as liquid filled in close system at
specify pressure these close system comprises of bulb ( of steel or
stainless Steel ) , a Micro bore capallery (of steel or Stainless
steel ) and spiral or "C" Shape bourdon tube. When these system is
heated or cooled at the bulb end the mercury in the bulb expands or
contracts and pressure is incresed or decreased within. These
puressure moves the bourdon as this is only elastic element.This
movemnent is transmitted through a rack and pinion movemnet which
drives pointer thus showing the temp on the calibrated dial. The
accuracy is further improved upon by providing case compansation or
full compensation.
