At the heart of the AMETEK Model GM Resistance Thermometer is a platinum resistance sensor, which measures temperature based on the resistance of platinum metal as a function of temperature. Platinum resistance sensors offer excellent linearity and repeatability, as well as a wide temperature operating range and good long-term stability. The relationship between the resistance value and temperature of the sensor follows the temperature-resistance curve of the international standard, which is usually calibrated according to the IEC 60751 standard Pt100 or Pt1000 RTD.

These thermometers are usually equipped with high-precision electronic circuitry that reads the resistance value of the sensor and converts it into a temperature reading. The circuit design takes into account temperature compensation, noise suppression, and signal amplification to ensure the accuracy and reliability of the measurement data. In addition, AMTEK Model GM resistance thermometers may include digital displays, analog outputs, communication interfaces (e.g., RS232 or USB), and remote control capabilities to accommodate different measurement needs and automation system integration.

AMETEK Model GM Resistance Thermometers are widely used in industrial processes that require precise temperature control, such as chemical production, petroleum refining, power generation, and food processing. In these applications, accurate temperature measurement is essential to ensure product quality, improve energy efficiency, and maintain production safety. In addition, these thermometers are also an important tool for standard temperature measurement and calibration in scientific research and laboratory tests.
