Can I use a tribrach with an optical plummet?
A tribrach can be used with an optical plummet or any other survey instrument, which can include but may not be limited to:
It allows you to attach these instruments to a tripod, so you can achieve more stability while you’re using it.
Can I use a tribrach with a total station?
You can use a laser tribrach with any type of laser measuring tool, but you can also use it with a total station or any other surveying instrument. This device will allow you to attach your instrument to a tripod, so it can be more stable while you’re using it.
The torsional rigidity of the original
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.
The ideal tribrach for your application
All original tribrachs comply with the strict specifications and quality standards of Leica Geosystems. Your choice should ideally be made according to your individual accuracy requirements.
Professional 5000: Hysteresis maximum of 1" (0.3 mgon) or better
Professional 3000: Hysteresis maximum of 3" (1.0 mgon)
Professional 1000: Hysteresis maximum of 5" (1.5 mgon)
Leica Tribrach
Similarly to the stability of the tripod, that of the tribrach is a significant factor in measurement accuracy. The torsional rigidity, the most important criterion of a tribrach, is constantly controlled and tested during its production. The maintenance-free foot screws of the Leica Geosystems tribrach provide movement that is always smooth and free of play, even after years of use. The precise alignment of the support area to the base plate of the instrument assures extremely accurate forced centring. The optical plummet is so robust that the need for adjustment during the entire lifetime of the tribrach is practically unnecessary. Its construction predestines the tribrach for all applications, including extreme temperatures and high dust and humidity.
