L'explication/l'anotation:For operational production control of prestresses in rod, wired and wire-rope fitting of reinforced concrete constructions by the frequency domain method according to the state standard 22362.
La description détaillée de marque:In contrast to analogues the ÝÈÍ-ÌÃ4 device has functions of automated fulfilment of technological calculations:
- specified the fixture lengthenings;
- lengths of reinforcement blank;
- adjustments of separation between anchor heads;
for users, producing some types of preliminary strained reinforced concrete constructions, the option to install is provided and memorizings five combinations of initial data (separation between forms thrusts, diameter and class of fixture, design voltage in fixture). The device is provided by the non-volatile memory of measuring results and efficient two-circuit numerical filter, providing the suppression of electro-magnetic interferences and snags of harmonic composition of fluctuations of fixtures. In the process of meterage tacitly produces some measurements of vibration velocity of fixture, comparing them among themselves, selects the reliable size and transforms it in the mechanical strain in compliance with algorithm for computation. Indication of measuring result - digital, in MPa. the device has the òåñò-êîíòðîëÿ condition.
