triblachs

适合您应用的理想三元式

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.

原始的扭转刚度
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.

适合您应用的理想三元式
所有原始的Tribrachs都符合Leica Geosystems的严格规格和质量标准。理想情况下应根据您的个人准确性要求做出选择。

Professional 5000:滞后最大1英寸(0.3 mgon)或更好
专业3000:滞后最大3英寸(1.0 mgon)
专业1000:Hysteresis maximum of 5" (1.5 mgon)

GDF321 GDF322

专业的5000系列三元式的磁滞最大为1“(0.3 mgon)或更高。对于所有需要3英寸以下的角度测量的任务,建议使用此系列中的三元。由于滞后最小,我们建议将专业的5000系列用于所有电动仪器。

GDF311 GDF312

The hysteresis of the Professional 3000 Series tribrachs amounts to a maximum of 3" (1.0 mgon). The foot screws are maintenance-free and have a larger diameter. This allows for fine adjustments, even when wearing work gloves under difficult environmental conditions. These tribrachs are suitable for non-motorised TPS instruments with angle accuracy from 5" to 7" and GNSS antenna stations as well as backsights and control

GDF301 GDF302

专业1000系列Tribrachs的磁滞最大为5英寸(1.5 mgon)。GDF101和GDF102是经济有效的Tribrachs,证明自己在正常环境条件下使用。这些TRIBLACH适用于非运动的TPS仪器7英寸和单个频率GN​​SS天线站的精度。
