Analog temperature sensors are not a specific brand but a category of sensors used to measure temperature by converting thermal data into analog signals. These sensors are produced by various companies worldwide, including Texas Instruments (USA), Maxim Integrated (USA), and STMicroelectronics (Switzerland). They serve industries such as automotive, industrial automation, consumer electronics, and HVAC systems. Key products include thermocouples, RTDs (Resistance Temperature Detectors), and thermistors, which provide accurate and reliable temperature monitoring for critical applications.
