Oil & Gas
  • Indicates media temperature using a temperature-actuated liquid in the sensing element and a highly accurate, high quality pressure gauge
  • As the media temperature increases, the capillary fill fluid vaporizes, increasing pressure in the Bourdon tube to activate the movement and pointer for proper indication
  • Ranges available from -40 °F/C to 60 °F/C through 100 °F/C to 350 °F/C
  • 2-1/2", 4", 4-1/2" and 6" sizes
  • Brass, stainless steel, or phenolic case
  • Dry or liquid filled
  • Bottom, back or lower back connected
  • Mounting options: front or rear flange, bezel, and u-clamp
  • Capillary material: copper or stainless steel
  • Bulb material & dimensions: copper or stainless steel, 2-5/8" x 3/8" through 7-5/8" x 3/8"
  • The dial scale graduations are non-linear, therefore the highest degree of accuracy and readability is found in the upper half of the scale

     Note: Thermowells are recommended for pressure, corrosive fluids and high velocity applications.
