Concrete Strain Gages

Wide range of applications and easy handling-essential factors for choosing KYOWA strain gages.
Strain gages are designed to electrically detect ''strain,'' minute mechanical changes occurring in response to applied force. They are used not only for machines and moving objects but also in various fields including electrical equipment, civil engineering, building construction, chemicals and medicine. Strain gages enable detection of imperceptible elongations or shrinkages occurring in structures. Measurement of such elongations or shrinkages reveals the stress applied to the structure. Stress is an important factor to confirm the strength and safety of structures. KYOWA strain gages are available for measurement of varied types of strain, from static strain to dynamic strain occurring at higher than 100 kHz and impact-initiated strain.KYOWA strain gages also provide a wide range of applications and can conveniently be applied to structures of varied materials and shapes. In addition, strain gages are used as sensing elements for measuring load, pressure, acceleration,displacement and torque. Thus, they are widely utilized not only in experiments and research but also for industrial measurement and control. Over 50 years ago KYOWA produced the first strain gages in Japan, and based on the abundant experience and technologies accumulated throughout these years, the company now manufactures various kinds of high-performance strain gages to cope with multiple application environments


Strain Gages for Concrete

Description

KC

Wire Strain Gages

Featuring a longer gage length, the KC gages are wire strain gages suitable for mean strain measurement of concrete under test. Usually, a model with the gage length over 3 times longer than the maximum diameter of the aggregate is selected for the purpose.

KMC

Embeded Strain Gages for Concrete

The KMC gages are designed to measure self-shrinkage and self-stress of cemented materials. They enable measurement of the self-shrinkage of high-strength and highfluidity concrete from immediately after placing. They are also used effectively to check for cracks of cemented materials. Usually, a T-type thermocouple is installed near the gage, while the KMC gage of H4 type does not require such the installation since it is equipped with a built-in thermocouple.

KFG

General-purpose Foil Strain Gages

Listed here are leadwire-equipped gages selected from KFG gages applicable to strain measurement for concrete.

KM

Embedded Strain Gages

The KM gages are designed to be embedded in mortar or concrete for the purpose of measuring the internal stress. To ensure better adhesion to mortar or the like, the KM gages feature a specially treated surface. They also provide suitable waterproofness and elastic modulus for the intended purpose.
