Thermowells and Accessory

Connection between thermometer and process

Thermometer thermowells are the most important components of temperature measuring points. 
They protect the actual temperature sensors from aggressive media as well as high pressures and flow velocities and they seal the process towards the atmosphere. Only then, temperature measurements in highly stressed processes or in aggressive or toxic media are possible. Since the fields of application are almost unlimited, we offer thermowells in a wide range of construction types and materials. In addition to our extensive standard range, we provide almost any customer-specific version or coating.
