CARLSON STRAIN METER

DESCRIPTION

The Carlson Strain Meter is a device, which can be embedded in concrete to reveal the internal deformations. It responds to any change in dimension of the concrete, due to stress, creep, temperature change, moisture change or chemical growth. The main purpose of the strain meter, however, is to indirectly determine stress. Quick changes in stress are simply achieved by multiplying the measured strain by the modulus of elasticity. But for stress, which develops over a long period of time, account must be taken for changes in modulus of elasticity and of deformations due to creep and to all causes other than stress.

The standard strain meter may be embedded in concrete or attached to a surface with saddle mounts. The strain meter is furnished in three different lengths, from 8 cm to 51 cm (8 in. to 20 in.), but all with the identical sensing element. The end away from the cable has a tapped hole (¼ - 28 UNF) to permit attachment to a spider for mass concrete embedment, or to incorporate an extender thereby increasing the length and sensitivity. The body is covered with PVC sleeving to break the bond with the concrete.

The miniature strain meter is for embedment in concrete applications where small size is essential. The miniature strain meter is furnished in three different lengths, from 10 cm to 20 cm (4 in. to 10 in.), but all with the identical sensing element. The end away from the cable has a tapped hole (6 –32 UNF), which allows an extender to be added, thereby increasing the length and sensitivity. The body is covered with PVC sleeving to break the bond with the concrete.

The standard strain meters are intended for use in service structures, and the miniature strain meters are mainly for laboratory testing.

QUICK SPECS

Responds to stress, creep, temperature, moisture change or chemical growth.


Indirectly determines stress.

APPLICATIONS

Measures internal deformations in concrete.

BENEFITS

Increase Productivity


High Accuracy


High Reliability
