Material: Beryllium copper alloy.
Number of dynas per centimeter: 7140dynas at 100% spring torsion.
Outer diameter: 40mm
Inside Diameter: 10mm
Material thickness: 1mm
Material width: 1.5mm
How much rotation Angle and the corresponding torque generated:
Maximum torque: 673.2 N-mm (when the spring is at a maximum rotation of 330°)
The relationship between angle and torque is linear:
At 0° = 0 N-mm
At 165° (half) = 336.6 N-mm
At 330° (maximum) = 673.2 N-mm

Bending radius: 2.5mm
Function: Central fixation of the spring to the viscometer shaft
Hook shape:
"L" shape with gentle curve
Length: 12mm
Bending radius: 3 mm
Function: Connection to the measuring system
