Automatic Tension & Compression Testing Machine

Description

GENERAL PROPERTIES of Automatic Tension & Compression Testing Machine

UTM-3000.FPR automatic 500 kN tension / 1000 kN compression testing machine  has been designed to meet the need for reliable and consistent tensile testing of steel rebars up to 26 mm diameter and compression testing of concrete cube samples up to 150 mm and cylinders up to 160×320 mm.

This lightweight low cost and high accurate machine is suitable for use both in the site testing and educational purposes. UTM-3000.FPR  feature the complete automatic test cycle with a closed loop digital readout. Once the specimen parameters have been introduced, it is sufficient to press the START button to complete the test.

UTM-3000.FPR  tension/compression test machines consist of three main parts: Frame, power pack and data acquisition & control system. On the measuring system pressure transducer is used for load measurements and Linear Potentiometric Displacement Transducers is used for crossheads separation measurement and plotting stress/elongation graph. Each part has been designed to manufacture machines with a high degree of mechanical stability and complies to EN ISO 6892-1(method B), 15630-1  (with suitable platen set) standards.

FRAME

The load frame is a welded steel fabrication carrying the ball-seated upper platen or the universal grip assembly. Positively located on the loading ram which is protected from debris by a cover, the lower platen is marked for the centering of cube and cylinder specimens. The dimensions of the frame allow the tension tests on steel rebar up to 26 mm dia., and flat specimens up to 15mm thick and 50mm wide, compression tests on concrete cylinders up to 320 mm long x 160 mm diameter and cubes up to 150 mm. The machine is supplied complete with 5 pcs. 90 mm x Ø165, 2 pcs.  50 mm x Ø165 and  2 pcs. 30 mm x Ø165 distance pieces. To test samples shorter than 150 mm extra distance pieces should be ordered. The frame  have a double  acting  piston  with over travel protection to stop the motor when the maximum platen or grip travel be reached.
