BLT-12Resistance strain gauge embedded strain gauge

Application scope:

BLT-12Resistance strain gauge embedded strain gaugeUsing highly elastic materials and special processing techniques, high-precision and high-temperature resistant strain gauges are selected as sensitive components. Through processes such as bonding and bridge assembly, they are specially designed and manufactured for the characteristics of high deformation and shear strength of asphalt concrete, high environmental temperature, and strong vibration that can withstand the high temperature and pressure during asphalt pavement construction; This sensor has the advantages of high output sensitivity, good linearity, good stability, high accuracy, and easy installation and use. Mainly used for stress-strain measurement in the structural layers of asphalt roadbeds and pavements, as well as stress-strain monitoring of asphalt in black core walls of dams.connectableCollect data from dynamic and static strain gauges of various manufacturers.
