Removable Deformometer 200

///Removable Deformometer 200


Pizzi Instruments’ removable deformometer 200 is a portable mechanical crackmeter with a base of 200 mm used for the control and measurement of the behavior of small cracks and fractures or the movement of structural joints.

It is made either of a stainless steel or Invar body, complete and with tapered reference tips for measurement and an indicator dial, either analog or digital. The accuracy of the instrument is centesimal for the stainless model and millesimal for the invar model.
The standard base size is 200mm and the measuring range is 5 mm.
The measuring points are equipped with small circular seats positioned either side of the fissure into which the tips of deformometer are inserted during the survey.
Its main advantages are:
-ease of handling and simplicity of installation and reading
-speed of execution
Special design features make the instrument sturdy and totally protected from humidity and other weather conditions often found in environments subject to monitoring. The instrument comes with a calibrated control template (stainless steel or Invar), for verification and periodic calibration of the instrument and a shockproof carrying case.
Important feature of all our deformometers and crackmeters, as well as many of our other instruments, is total compatibility with products manufactured and developed by the Officine Galileo of Florence.
For specific needs and requests, we are able to design and manufacture customized products different from standard.


Structural and geotechnical monitoring; monitoring of cracks and surface deformations; integration with automatic measurements from electrical or vibrating wire crackmeters.
The deformometer is used for control and monitoring of:

  • Housing
  • Historical buildings
  • Dams
  • Monuments
  • Bridges
  • Tunnels
  • Other

Features and Benefits

The most important advantages in the use of our removable deformometer 200 are:

  • Great accuracy
  • High reliability
  • Small footprint
  • Good handling
  • Ability to carry out controls in several places in a very short time
  • Media compatibility with products developed by Officine Galileo of Florence

Measuring principle

Made of a rigid stainless steel or Invar bar, at one end is a fixed reference tip; at the other end , a second pivoted reference tip, free to rotate by a small angle equal to the measuring range of the instrument.
The movable tip hinge is made of a bearing in the stainless steel centesimal model and special blades rectified in the in Invar millesimal model
When measuring, the two conical tips are placed on two specific circular housings fixed to the wall, straddling the crack or joint or base of the deformation being measured. An accurate system of levers transduces the distance between the two reference tips on an analog or digital comparator.
Our gauges are supplied with a precision template for testing and periodic calibration of the instrument. . The round mountings provided for straddling the crack are special cylindrical tablets, with a calibrated hole to accommodate the tips.
