Update! E-RAD BLU-S
In addition to the regular E-RAD models, RAD has supplied the E-RAD-S for specific customers in the last couple of years. Now that this technology is working flawlessly we now offer a full range of “S” versions in addition to the standard E-RAD line up.
What difference does the “S” make?
The “S” version of the E-RAD distinguishes itself from the standard model in that it is equipped with 4-gauge torque transducer that is integrated in the annulus of the gearbox. This transducer measures the torque output from the square drive, so the actual torque transmitted to the bolted joint. So far really not something really new as this is similar technology as we feature on the TV-RAD tools, RT or Smart Socket™. However, unlike the other RAD transducer equipped tools, where the transducer is used to report or verify the torque, the “S” goes a step further in that it actually controls the precise moment of the torque shut off. This makes the E-RAD even more precise (2%!) and is basically insensitive for different joint conditions.
With the regular E-RAD, already very precise (3%), any inaccuracy caused by joint sensitivity was corrected by performing a point calibration or a “BLU Call” on the joint with a Smart Socket™. With the E-RAD-S this will not be necessary anymore and the tool will be always accurate on any joint.
The E-RAD-S works on a standard BLU controller case and functionality wise it is more or less identical as the regular E-RAD. An E-RAD-S Handle can be connected to an existing BLU controller if it has a recent software version.
