Presentation

The bolt force transducer KR29 has been designed for measuring the clamping force of a screwed assembly with bolts of diameter M5 to M16. The accuracy is in range of 1% of full scale.

Available in 3 measuring ranges from 0-2kN to 0-10 kN, KR29 features a robust design (stainless steel, IP 65, overload protection of 150%) and an operating temperature range between -10 and 85 ° C . A high temperature version is also available, operating from -40 to +180°C, and compensated from -20 to 150°C.

A complete 5-point factory calibration certificate is supplied with each sensor (9 repetitions)
