The accuracy with which a tribrach returns to its starting position once the instrument has stopped, is called torsional rigidity or hysteresis. This hysteresis is the relative movement between the top plate and the base plate of a tribrach that occurs through the rotation of a TPS instrument. The hysteresis has direct influence on the angular accuracy of the instrument – and that speaks for the original. To optimise the hysteresis as Leica Geosystems has done is complex and calls for the highest precision: a movement of the upper plate to the lower plate of 0.3μm corresponds to an angle error of 1”. Especially motorised instruments with their high acceleration and brake power require tribrachs with very high torsional rigidity.

Sokkia Tribrach with optical plummet

The Sokkia WA201 Precision Tribrach with Optical Plummet is a high-quality and durable tribrach for lasers and other optical instruments. It has a base plate with a standard 5/8 x 11 thread to allow mounting of most instruments.

The WA201 tribrach features a push-pull slide focus, an optical plummet used to center the instrument over a point, in place of a plumb bob, and a circular level vial with a sensitivity of 10 feet per 2mm. It is compatible with Leica, Geomax, Sokkia GPS and EDM accessories, electronic and optical Theodolites.
