What is a current controlled smart electric screwdriver?
The desired target torque can be set in the controller which will adjust the current level supplied to the smart electric screwdriver and automatically reach the defined goals and parameters, based on calculations from parameters such as friction and heat.
There is an open loop with one-way communication from the controller to tool only.
What is a transducerised smart electric screwdriver?
A transducerized smart screwdriver is the most intelligent tool in the market. It has a transducer inside the tool helping to precisely measure the real calibrated torque applied at each joint and every tightening.
There is a feedback loop between the built-in transducer & the controller. The real torque values will always be sent back to the controller from the tool.
The highly reliable torque data collected from transducerized smart screwdriver will further enhance the detection & traceability of tightening errors and facilitate production optimization.
