The Watlow G12A45-L12 and G12A45L12 are high-performance industrial temperature sensors designed for various applications where precise temperature measurement is crucial. These sensors are part of Watlow's G-Series thermocouple product line, which is recognized for its ruggedness, accuracy, and reliability.
The G12A45-L12 and G12A45L12 sensors are Type K thermocouples, which use Chromel (Nickel-Chromium alloy) as the hot junction material and Alumel (Nickel-Aluminum alloy) as the cold junction material. This combination provides excellent temperature measurement capabilities from -200 C to 1260 C (-328 F to 2282 F).
The sensors are compact and lightweight, with the G12A45-L12 measuring 3.8 inches (96.5 mm) long and 0.3 inches (7.6 mm) in diameter. The G12A45L12 is slightly shorter, measuring 3.1 inches (78.7 mm) long and 0.3 inches (7.6 mm) in diameter. Both sensors have a thin-walled, ground-signal design that minimizes self-heating, ensuring accurate readings even in high-temperature environments.
The sensors come with a stainless steel sheath for added protection against harsh environments. The sheath is available in various lengths to accommodate various application requirements. The sensors also feature a threaded connection for easy installation and removal.
The G12A45-L12 and G12A45L12 sensors are suitable for use in various industries, including oil and gas, chemicals, power generation, and food processing. They are ideal for measuring temperatures in high-temperature processes, furnaces, kilns, and other applications where precise temperature control is essential.
Watlow's G12A45-L12 and G12A45L12 sensors are designed to provide accurate, reliable, and long-lasting temperature measurement. They are built to withstand the rigors of industrial applications and come with a one-year warranty against manufacturing defects. With their high temperature range, compact design, and rugged construction, these sensors are an excellent choice for any application that requires precise temperature measurement in harsh environments.
