Krautkramer — HT400A High Temperature Probe (5 MHz, 0.50")
Ultrasonic Contact Transducer for Elevated Temperature Applications (Up to 1000°F) SKU: 113-224-760Overview
The Krautkramer HT400A High Temperature Probe is a specialized ultrasonic transducer designed for thickness measurement and inspection in extreme temperature environments. Operating at 5 MHz with a 0.50" contact diameter, this probe provides a balanced combination of penetration and resolution for accurate measurements on hot materials.
Engineered to withstand temperatures up to 1000°F (538°C), the HT400A enables in-service inspection without the need for shutdown or cooling, significantly improving operational efficiency. Its robust construction and high-temperature capability make it suitable for demanding applications where conventional probes cannot perform.
Designed for compatibility with ultrasonic thickness gauges and flaw detectors, this probe is widely used in industries such as power generation, petrochemical, and process manufacturing where high-temperature monitoring is critical.
