Widest portfolio of adsorbent technologies for a broad spectrum of applications. Catalytic converters for aircraft cabins and fuel inerting. Cathode materials, e-mobility, next-generation technology solutions. Air cleaners that help to improve indoor air quality. Solutions for the most challenging applications. BASF maintains significant diesel research and development facilities around the world. These facilities are being used to develop the technologies needed to meet the extremely low emission levels called for in new emissions regulations. As the global leader in mobile emissions catalysts, BASF has developed a number of specialized catalyst technologies. BASF offers a "full loop" of precious metals products & services. Catalysts for chemical, petrochemical, and refining industries. We offer precious metals supply and full-loop management services, including refining to recover precious metals from spent catalysts. The development of fuels and chemicals based on biological feedstocks is critical to a sustainable future and BASF is proud to provide the catalysts to support this industry. BASF has established itself as a front-runner in this field by becoming the global market leader for sodium methylate, the homogeneous catalyst used for biodiesel production. BASF catalyst technologies play a crucial role in the manufacture of a wide range of fine and specialty chemical products including flavor and fragrances, herbicides and pesticides, resins, pigments and dyestuffs, pharmaceuticals, and plastic and rubber additives. Chemistry plays an important role in the transformation of vegetable oils to products for our daily life. Catalysts are an indispensable tool to make this transformation possible. BASF offers more than 125 years of experience with oxidation catalysts. Each percent of catalyst selectivity advantage creates additional value and reduces COx emission. Solutions for power plants, process industries and more. BASF Catalysts has long been a leader in the development of highly active, robust and selective catalysts and related technologies for the destruction of volatile organic compounds (VOC). Thermocouples, pyrometers - insights for higher yields. Our contact temperature probes include high temperature thermocouples, platinum thermocouples, noble metal thermocouples, thermocouples for the glass industry, profile and spike thermocouples for diffusion furnaces, high temperature industrial thermocouples, furnace thermocouples, and high temperature thermocouple wire and cable. A specialty of BASF for many years is the glass thermocouple. We have grown with the industry and, as glass technology requirements have expanded and changed over the years. Offering excellent accuracy, resolution, repeatability, and stability, EXACTUS® optical pyrometer technology provides significant performance advantages in non-contact temperature measurement in a practical, rugged and user-friendly design.

Enclad Cable and Thermocouple

BASF Enclad^® products are a precise and rigorously controlled combination of select precious and base metal sheaths, high-purity ceramic insulations and compatible precious metal thermocouple wires consolidated into a rugged assembly which is bendable into difficult to reach places. Enclad products include cable, standard thermocouples and composite-sheath thermocouples.

Enclad thermocouples have been extensively used in the following select applications in which high temperature resistance or chemical inertness of the sheath material is required:

Crystal growth
Gas turbine combustor discharge
Liquid phase epitaxy
Biomedical research
Ion implant
Glass melting and working

Ceramic sintering
Refractory erosion monitoring
Nuclear research
Soaking pit control
Heat-treating furnaces
Energy conversion
Plasma physics research

Specification

Specifying sheath materials - The choice of the outer sheath material must be made after considering its compatibility with the environment, its operating temperature and its structural loading. In general, the following temperatures have been found suitable for Enclad sheath materials:

Pt— 1200°C
ODS Pt— 1600°C
Pt-10Rh— 1500°C
Pt-20Rh— 1650°C
Inconel 600— 800°C

Specifying thermocouple materials

Type S and R thermocouple material are the most popular in the platinum-rhodium system. They are noted for excellent stability up to their recommended maximum-use temperature of 1400°C.

Type B thermocouples have proved effective for applications up to 1750°C, with excellent stability and sensitivity
