Inverted force-pull tensiometer

FIG. 1 Schematics of inverted force-pull tensiometers used in our laboratory. The schematic on the left shows the case where a micrometer is directly mounted above a balance for the machine on the right, a converter arm was used in conjunction with an electronically controlled stepper motor.
