Conax EtchDefender™ Technology

Up to 3X longer life and savings of 35%-45%

Conax introduces EtchDefender™—the patented solution for extending the life of quartz thermocouple sheaths. EtchDefender™ is a quartz coating technology that can triple the life of the quartz sheath and provide savings of 35% to 45%. Conax’s cutting-edge technology has been tested both in the laboratory and in a production environment at a major wafer manufacturing facility.

EtchDefender™ advantages

Laboratory and production testing have shown:

  • No particulation
  • Increased Durability
  • Slower quartz devitrification
  • Slower quartz erosion
  • Longer life

Highest Quality

We manufacture our sensors using the best available materials, cleanest assembly cell and the finest workmanship in the industry.

Best Available Materials

  • Pt and Pt/Rh wires are manufactured from mined ores – never manufactured from recycled materials
  • Quartzware is exclusively semiconductor grade with 3 available levels of quality
  • Insulators are of 99.5% purity or better, and are fired to remove organic impurities
  • Connectors are laser engraved with serial numbers

Finest Workmanship

  • Experienced and certified assemblers are used for every operation
  • Electronic process flow, work instructions and revision control ensure manufacturing integrity
  • Rigorous testing is performed at all assembly steps
  • Precision laser welding is used to microscopically weld and immediately inspect the quality of every junction.  The process minimizes HAZ (Heat Affected Zone) damage to the very small diameter wires and junctions used within the product line
  • AS9100, ISO 9001 Certified

Cleanest Assembly Cell

  • State-of-the-art assembly cell incorporates key clean room standards that minimize airborne particles
  • Laminar flow tables are used for assembly operations
  • Assemblers are outfitted in clean room apparel, gloves and magnifying goggles

 

Customized Designs

We are the only manufacturer who can customize designs and configure sensor sets that optimize our customers’ performance objectives.  We start specifying our sensors using a base configuration model comprised of selecting one of 7 quartz sheath thickness options and one of 4 wire diameter options, creating the possibility of 28 base configuration models.

Series 49: 0.049” (1.250mm) Variation 08: 0.008” (.203mm)
Series 39: 0.039” (1.000mm) Variation 10: 0.010” (.254mm)
Series 31: 0.031” (0.800mm) Variation 12: 0.012” (.305mm)
Series 29: 0.029” (0.725mm)
Series 23: 0.023” (0.575mm)
Series 20: 0.020” (0.500mm)

Other customized features include specifying:

  • NEW EtchDefender™ quartz sheath coating – up to 3X longer life
  •  3 quality grades of quartz sheaths
Quartz Quality Index:
Series Number XXXXP = Premium Quality Quartz
Series Number XXXXE = Enhanced Quality Quartz
Series Number XXXXS = Standard OEM Quality Quartz (Semiconductor Grade)
  • Center TC tip options – grounded or non-grounded
  • Diffusion options – non-diffused or diffused
  • Thermocouple wires – special long-life thermocouple wire options are available
  • Packing – standard or special
