GEDORE S DREMOMETER - permanent precision Torque wrench made of high-strength aluminium alloy Drive in accordance with application DREMOMETERS are available for a large variety of applications in controlled screw tightening. The single square drive for controlled clockwise tightening or the double square drive (L) for controlled bi-directional tightening. Special utilisation areas for DREMOMETER with spigot end (Z) and rectangular cavity (SE) particularly for hard-to-access locations and where space is tight. Almost all DREMOMETER models have separate ratchet heads and there are good reasons for that It is possible to work with or without the ratchet head function as desired. I Robust and unsusceptible The full-metal construction of the DREMOMETER makes it particularly unsusceptible to grime and rough handling on construction sites in workshops and in industry. I m & 3% Classified to DIN EN ISO 6789:2003 Type II Class A with a factory certificate allowing for operations to be traced back. Calibrated to a permitted + - 3 % deviation and better. The specifications of the standard (+ - 4 %) are exceeded. Automatic resetting The DREMOMETER gives operator an audible signal and tactile impulse and is back in operation in an instant. Working principle The quality lever chain produced in the company's own drop forge reduces the strain on the mechanics to a minimum. The proportioning of the individual levers which are optimally attuned to each other gives the DREMOMETER its unique precision and its long tool life. 1 l b - q Z 8-1000 N-n (1) Position of the lever chain without impact of force (in starting position). (2) Position of the lever chain with impact of force before the set torque is achieved. The force is transferred from the primary lever to the intermediary and final lever until the final lever slips past the so-called release lever through the sliding back of the angle-lever body. (3) Position of the lever chain when the force impacts after the torque setting is achieved. Immediate position after the clear tactile impulse and audible signal "click". On relief the lever chain moves back into the starting position (1). SE I2 I 114x18 1 8-400 N-m 260
