The WIKA Model TG51 bimetal thermometer is engineered to meet ASME B40.200 standards, delivering reliable temperature indication in demanding industrial environments. Its hermetically sealed 304 stainless steel case provides NEMA 4X (IP66) protection, ensuring resistance to moisture, dust, and corrosion.

The 3-inch dial with back mount configuration simplifies installation in confined spaces. Stem lengths are available from 2.5 to 6 inches, accommodating various pipe and equipment depths. With ±1% full scale accuracy, the TG51 offers dependable performance for general industrial applications.

The TG51 covers temperature ranges from -50 to 550 °C (-58 to 1,000 °F) across multiple dial configurations, with a standard 1/4-inch (6.35 mm) stem diameter and 1/2 NPT process connection. The flat instrument glass window and all-stainless-steel construction ensure readability and durability in harsh environments including chemical processing, power generation, and food and beverage production.

Typical applications span machine building, microbrewing, boilers, water and wastewater systems, piping, HVAC, and general industrial process monitoring where reliable local temperature indication is required.
