Tension strips and torsion strips for galvanometers

Tension strips and torsion strips for galvanometers

Instead of an axis, galvanometers with tension strip mounting have two metal strips that are spring loaded. The tension strips are used for the power supply to the rotary coil and their torsional moment for return.

Our tension strips and torsion strips at a glance

Functions

  • Mounting of the mobile system
  • Power supply
  • Retraction torque

Requirements

  • High breaking load
  • Low electric resistance
  • Low elastic aftereffect and good zero stability

Common delivery options: Available by the meters on coils, cut as piece goods, as C or Ω-shape, and twisted.

Tension strips and torsion strips are manufactured specifically to customer requirements.

Torsional moments

  • From 0.001mNcm/90° to 90.0mNcm/90°

Smallest dimensions with the tightest torque tolerances.
