Bimetal Thermometer

CASE AND BEZEL

 

  • 304 stainless steel standard
  • 316 stainless steel optional
  • All external parts corrosion resistant to most chemicals
  • Parts designed for maximum strength to meet requirements of heavy duty industrial applications
  • Manufactured with precision tooling on modern OSHA approved stamping equipment
  • Statistical Process Control QA methods used to assure component quality and process consistency
  • Polished finish identifies Tel-Tru quality
  • Cases may be silicone filled for additional dampening of extreme vibration, or to assure consistent performance in low process temperature/high environmental humidity applications

 

HERMETIC SEAL

 

  • Case/Bezel assembly is a precision interference fit
  • Silicone gasket provides dustproof and leakproof seal
  • Welded construction-Unique 360º TIG weld joins case, stem and threaded connection
  • Testing conforms with ASME B40.3 procedures

 

THREADED CONNECTION

 

  • 304 stainless steel standard
  • 316 stainless steel optional
  • Precision manufactured on Tel-Tru CNC machines
  • Statistical Process Control QA methods used to assure component quality and process consistency

 

LENS

  • Extra heavy duty instrument glass standard
  • Shatterproof glass, tempered glass, and plastics optional

POINTER

 

  • Black painted aluminum
  • Balanced and precisely assembled to bimetal coil stem
  • Direct transfer of coil movement to temperature displayed on dial

 

EXTERNAL RESET

 

  • Calibration adjustment using an Allen wrench discourages inadvertent tampering
  • Stainless steel pinion is sealed with a silicone “O” ring to maintain integrity of hermetic seal
  • Pinion works with gear teeth cut and formed in dial • Models without reset are available

 

DIAL

  • True anti-parallax dial on 3″, 4″‘ 5″ models
  • Graduations on dial ring are on the same plane as the pointer tip minimizing reading error
  • Concave design of dial ring enhances readability
  • White appearing .032″ anodized aluminum
  • Graduations for each temperature range are calculated to match deflection data of bimetallic material
  • Large easy to read black numerals and graduations are printed on precision pad printing equipment
