IBJ - Model BBS X DS Series - Bridge Bearing Stress Sensor
The sensor detects the compression of a metal body. This metal body is 2 components resin and protected housing. The housing is arranged in concrete or in the iron braid of reinforcement. The compression are measured with ultrasonic pulseecho method. In the case of concrete tension sensor, an ultrasonic sensor is included. The runtime in the measuring element is measured in high resolution with a separate stress meter. All ultrasound devices to the bolt measurement with a maximum frequency of 10 MHz is suitable for the measurement.
Product Overview
The term declines linearly with the compression in the elastic range.
Which the compressive stress sensor surrounding concrete is a compression of the measuring element. The change in the length of the measuring element is not only dependent on the load or stress, but also on the temperature.
Both factors taken into account the ultrasound measuring device for measuring the change in length. A permanent temperature measurement is integrated into the pressure voltage sensor. This temperature sensor work as 1-wire sensor with ROM for the identification.
For universal use, the sensor for all devices for the measurement of bolt is suitable regardless of the manufacturer. The automatic temperature correction of these devices can be used, a second is incorporated independent temperature sensor.
The term due to the change in length and acousto elastical effect has reduced the influence of the surrounding concrete on the measuring element.
