HKB series for mid-temperature
Key features
HKB series strain gages are weldable strain gages with IP67 protection class. They are used in harsh conditions, when standard bonding of the gages is impossible due to high humidity, impossibility to clean the test object, etc. These strain gages are installed on the test object using dot welding machine. Operating temperatures range is -30…+250°C.Characteristics
