Clegg hammer test sheets electrical

The basic principle behind the Clegg Impact Soil Tester is to obtain a measurement of the deceleration of a free falling mass (Hammer) from a set height onto a surface under test. The impact of the hammer produces an electrical pulse, which is converted and displayed on the Control Unit in units of gravities "G" or tens of gravities "CIT".

The hammer has a mass of 20 Kg and a diameter of 130 mm. To simplify carriage and handling, the tester guide tube is fitted with wheels, making it into a pull-along cart, and the readout is fixed to the handle. Data Sheets and Technical Notes on all Clegg Products and Services are available from SDi on request.

The Electrical Density Gauge (EDG) is a nuclear-free alternative for determining the moisture and density of compacted soils used in road beds and foundations. The EDG is a portable, battery-powered instrument capable of being used anywhere without the concerns and regulations associated with nuclear safety. 17 33 Dynamic Cone Penetration DCP Test Procedure 1 Place the DCP point on the from CVEN 2401 at University of New South Wales

In cricket the Clegg Impact Hammer soil test is a good predictor of both bounce and pace. This makes it a useful addition for an unbiased determination of playing surface quality. Winter sports which have a risk of injury due to hard ground can similarly take advantage of the unbiased results provided by the Clegg Impact Hammer to aid decisions ... A Schmidt hammer, also known as a Swiss hammer or a rebound hammer or concrete hammer test, is a device to measure the elastic properties or strength of concrete or rock, mainly surface hardness and penetration resistance. It was invented by Ernst Schmidt, a Swiss engineer. Dr Baden Clegg Pty Ltd, founding director Dr Baden Clegg, was established in 1993 to provide an Information Service for the Clegg Impact Soil Tester, also known as the Clegg Hammer. Core to our company's activities are sales, marketing and manufacturing of the Clegg Hammer along with R&D work regarding the Clegg Hammer and other related soil ... When the hammer is released from a fixed height, it falls through the tube and strikes the surface under test, decelerating at a rate determined by the stiffness of the material within the region of impact. A precision accelerometer mounted on the hammer generates an electrical charge which is fed by a cable to a hand-held digital readout unit. Clegg Turf Soil Impact Tester The 2.25kg Turf Clegg is a Impact Soil Tester designed and manufactured for an easy and straightforward means for measuring the hardness condition of sports surfaces. Designed for the specific use in turf compaction management, the lighter 2.25kg Clegg is based on the popular Clegg Professional model.
