Description :

Series SIS-120 offers the following:

• Crackmeter SIS 120A - designed to measure movement in surface crack and joints
• Displacement Transducer SIS 121 – designed for measuring linear displacement in
• Borehole Extensometer
• Socket Assembly - facilitate assembly of Joint meter in concrete/masonry Dams.
• Mounting Brackets - facilitate the use of joint Meter for crack measurement

Operation :The Crackmeter transducer employs a shaft coupled by a spring, which is attached to heat treated high tensile strength steel wire. Movement of the shaft changes the tension in the spring and in the wire causing a corresponding change in its frequency of vibration. The wire is plucked by energizing the coil magnet so that it vibrates at its natural resonant frequency. The resonant frequency is proportional to the square root of the tension of the wire. A conventional readout unit can accurately measure the frequency of the wire. A microprocessor based readout unit can display the frequency as well as the value of the measured pressure directly in engineering units.

The Crackmeter are suitable for connection to data loggers for recording data in engineering units automatically at pre determined intervals. By the use of appropriate software, the data logger can present recorded data in desired formats, predict trends of variations and even generate alarms at pre-determined set points. The thermistor mounted in the Jointmeter and crack meter enables simultaneous measurement of temperature. This allows any corrections to be made in the observed readings due to temperature changes. Crackmeter with lightning protection is available on request.
