Receptor measured values.

RECEIVER according to the invention MEASURED VALUE FOR EXPANSION OF MEASUREMENTS FOR EXAMPLE CONCRETE OR CONCRETE INJECTION (13) comprises a carrier (6) WHICH IS LESS THAN expandability distensibility CUT MATERIAL Tranversal 812) DISPLACED BY THE RECEIVER. AT BOTH ENDS OF CARRIER (6) ELEMENTS ARE PLACED CROSS (1) FOR INTRODUCTION OF FORCE. By combining ELEMENTS CROSS RELATIVELY RIGID AND ENOUGH BIG WITH A CARRIER (6) WITH KNOWN AND VERY SMALL expandability, PROVIDED WITH SAFETY dilations in concrete (13) IMPOSING FULLY ON CROSS ELEMENTS (1) CARRIER (6) and measured MEASUREMENTS ON EXPANSION IN CARRIER (6) THE EXPANSION OF CONCRETE (13) directly and without deformation. CARRIER (6) is formed CONVENIENT WAY AS ALUMINUM PROFILE HOLLOW PLASTIC OR MATTER, IN ANOTHER PROFILE (4) INTRODUCED, FOR EXAMPLE OF STEEL TO GET A PROPER FLEXIBILITY.
