Accurate temperature measurement is one of the most critical parameters in industrial automation. From chemical processing and food production to energy generation and pharmaceutical manufacturing, reliable temperature monitoring ensures product quality, process efficiency, and operational safety.
The DX-ETT Temperature Sensor and Transmitter Series is designed to deliver highly accurate and dependable temperature measurement in demanding industrial environments. Utilizing proven Pt100 resistance thermometer technology, DX-ETT sensors provide precise temperature data for monitoring, control, and automation systems.
What is the DX-ETT Temperature Sensor?
The DX-ETT series consists of industrial resistance temperature detectors (RTDs) and temperature transmitters based on the internationally recognized Pt100 sensor technology according to EN 60751 standards.
The measurement principle relies on the predictable change in electrical resistance of platinum elements as temperature varies. By measuring this resistance, the sensor accurately determines process temperature and transmits the information to control systems.
DX-ETT sensors are available in multiple configurations, including threaded, flanged, clamp-mounted, and sanitary process connections, making them suitable for virtually any industrial application.
How Does Pt100 Technology Work?
A Pt100 sensor has a resistance of 100 ohms at 0°C. As temperature increases, the resistance changes proportionally. This change is measured and converted into a temperature value by transmitters or control systems.
Pt100 technology is widely preferred because of its:
- High measurement accuracy
- Excellent repeatability
- Long-term stability
- Wide operating temperature range
- Resistance to harsh industrial conditions
The DX-ETT series supports temperature measurements from -50°C up to +395°C, depending on the selected model.
