Thermocouple Technology, LLC (TTEC) products

TTEC Bearing Temperature Thermocouples and RTD`s feature reliable spring loaded temperature measurements of Bearing Surfaces in Power Plants. TTEC`s unique Oil Seal, Spring Loaded Fitting ensures firm sensor tip contact with the Bearing Surface. These Assemblies can be specified to the exact length needed or ordered as a KWIK-FIT Field Cuttable Probe and cut to length in the field. For Thermocouples: See TECPAK Styles 1022,1019 and KWIK-FIT Style 1060-J, K, T or E Probes with 1060-33 Fitting and Accessories. For RTD`s: See SERIES 8000 Styles 8022, 8019 and KWIK-FIT Style 1060-A, B, C or D Probes with 1060-33 Fittings & Accessories.

TTEC manufactures Thermocouple Assemblies for severe high temperature corrosive environments. These assemblies utilize an HR160 Thermowell or Protection Tube. HR160 is a solid, solution strengthened NI-Co-Cr-Si Alloy with outstanding resistance to various forms of high temperature corrosion attack. Outstanding High Temperature Corrosion Resistance. High levels of Cr & Si combine to form a very protective surface Oxide scale that resists attack from Sulfur, Chlorine, Fluorine, Vanadium, Phosphorous & Salt deposits to 2200 ºF (1204 ºC). Life extensions greater than 10x compared to Ni-Cr alloys & stainless steels are common.

TTEC CFB Boiler Assemblies are specially designed to withstand the highly erosive conditions found in Circulating Fluidized Bed Boilers. These rugged assemblies are installed throughout the Combustor Section, Cyclone Inlets, Cyclone Outlets and in the Coal/Ash Feed Lines. They provide critical temperature inputs to the Fluidized Bed Supervisory System for indication, control & safety. TTEC CFB Boiler Assemblies utilize a unique Protection Tube with a special heavy-duty tip and the TTEC MVD Abrasion Resistant Treatment. This design has been proven to provide superior product life in very erosive environments with temperatures as high as 1800°F. Customers have encountered product life of 1 year or longer in the high erosion areas and over 4 years in the low erosion areas (upper area of the Combustor). TTEC CFB Boiler Assemblies are designed to withstand hostile environments characterized by exposure to CO, CO2, SO2, NOX & NH3, Bituminous Coal, Limestone, and Ash.

Stainless Steel Compression Weld-In Place Pad allows removal of Thermocouple from Pad. Easily installed: Pad is welded to surface, thermocouple is inserted into pad and secured via compression nut & ferrule. Simplifies Maintenance & reduces costs as Thermocouple Pads remain in position and are re-used when Thermocouples are replaced. Rugged TECPAK MgO Thermocouple with Flat Tip allows for accurate & reliable surface Temperature Measurements. Pads can be Flat or Curved with Stainless Steel or Teflon Ferrules. Ideal for non-intrusive Tank wall, process piping or boiler tube surface measurements. Type K Simplex. Grounded Measuring Junction. .250" O.D. – 316SS Sheath. Flexible Teflon Leads with strain relief spring. Other Terminations & Custom Versions available.

These easy to use, adjustable sensors are specially designed to be adapted to standard Thermowells (.260 bore & larger). Adjustable over entire length of stainless steel flexible armored cable. Eliminates stocking many fixed length probes. Thermocouple (J, K, T, E) or RTD (PT100 Ohms at 0ºC, .00385 TCR) Styles. Variety of Terminations available. Use with TTEC # 5601W Thermowell Adapter. Thermocouple Accuracy: Standard Limits of error per ANSI MC96.1. RTD Accuracy: DIN 43760 Class B. Special Tolerances available. Spring Loaded design maintains firm tip contact with Thermowell bottom. All Sensors are single element. RTD´s are 3-wire type. Factory tested... quality assured.

Accurate Temperature Measurements of Magnetic Surfaces. Spring Loaded Thermocouple. Firmly held in place on surface by Magnet. Flexible leads with Stainless Steel overbraid. Miniature Plug Termination standard. Length customer specified. Custom versions available.

TTEC Steam Line Thermowells and Assemblies are utilized in the demanding conditions found in Power Plant Steam Lines. These designs are characterized by Weld- In Thermowells in various standard and specialty materials including Stainless (316) and Chrome Moly Steels (F11, F22 and F91). These heavy duty, drilled barstock wells are available in Pipe Sizes up to 1 1/2 or to customer specifications. Material Test Reports ensure full traceability of materials. Optional Stress Calculations with Certificate are available per ASME PTC 19.3 TW-2010. Stamped tag numbers on each well allow for easy identification in the field. TTEC Steam Line Assemblies feature rugged, spring loaded TECPAK thermocouple elements to ensure firm sensor tip contact with the Thermowell and maximum performance. Custom designs available.
