FAQ

Q. What is PiezoBolt

A. Bolt-type Piezo sensor developed in Germany.

Q.What can be measured by PiezoBolt?

A. PiezoBolt is a load sensor that measures changes in axial force applied to bolts.
By replacing existing bolts, you can evaluate changes in load conditions at bolt fastening locations.
It has high responsiveness and can handle not only fluctuations in load but also vibration.

Q.How does PiezoBolt work?

A. PiezoBolt has a piezoelectric sensor unit made of piezo elements embedded in the bottom of the bolt neck. After tightening the bolt, measurement is performed using the charge output of the piezoelectric sensor unit according to changes in tension and compression applied to the bottom of the neck.

Q. What size bolts are supported?

A. Compatible with hexagon socket head cap bolts of M6, M8, M10, M12, M16, M20. Please check this link for details.
→ Specification❐ 

Q. What is the minimum bolt size?

A. The smallest size is M6.
The length of the thread can be shortened.
For example, if the thread is shortened to 6mm, the neck length will be about 21mm.

Q. What is the maximum bolt size?

A. The largest size is M20.

Q. What is the heat resistance temperature of PiezoBolt?

A. 180°C for M12 and below, 70°C for others.
