1. A clamping tool, comprising:
a body including control circuits and electronic processing circuitry, and having, at one end, a handle for gripping by an operator making a clamping, and on an other end, an arm, the arm comprising, at a free end, a seat that can be alternatively pluggable to a plurality of inserts configured to engage the clamping tool with a corresponding type and/or dimension of a mechanical member on which the clamping tool is configured to operate to perform a clamping operation,
a sensor provided in the arm and configured to detect tightening conditions exerted on the mechanical member, and
a microprocessor electronic card provided in the arm and configured to receive analog signals from the sensor, convert the analog signals into a digital format, and transfer the signals in the digital format to the electronic processing circuitry of the body,
wherein the arm is removably connected to the body through a connector allowing both a mechanical connection and transmission/reception of electrical and power supply signals between the arm and the body, and
the sensor and the microprocessor electronic card are inserted in a single support inside the arm.
