Features
- Operating range -40...+150 °C
- Pt100, Pt1000, Nickel RTD or NTC thermistor
- Flexible silicone rubber sensor protection
Description
ET244 surface temperature sensor is designed for measuring temperature on flat or slightly curved surfaces. The sensing element is encapsulated in a flexible protection cap made of silicone rubber. The sensor is fixed on the surface with adhesive acrylic film.
Due to its small size and ease of use, the device is an excellent solution for HVAC applications.
ET244 sensor is available with a variety of options for sensing element and cable.
