Isolated temperature sensor is not a specific brand but a category of sensors used in industrial applications. These sensors are designed to measure temperature in environments where electrical isolation is required to prevent interference or damage. They are commonly used in industries such as manufacturing, automotive, and HVAC. Companies like Texas Instruments (USA), Omega Engineering (USA), and Endress+Hauser (Switzerland) produce isolated temperature sensors. These products include thermocouples, RTDs, and infrared sensors, often integrated with signal conditioning for accurate readings in harsh conditions.
