6. The measurement-chain setup

A measurement chain is required for the transducer to take measurements. 

The measurement chain consists of:

 

• a torque transducer

 

• a connection cable 

 

• a power supply and display unit 

A power supply is required to supply the transducer with the necessary opera-

ting voltage. The transducer is fitted with a measurement amplifier (hence, no 

other amplifier is needed). The measurement data can be transmitted to a lap-

top, for example, or displayed and analyzed with power supply and display units.
