1A theodolite for the rapid measurement of distances in surveying.
（快速测定距离的）视距计，速测仪
Example sentencesExamples
Surveyors use a tachymeter to make quick calculations of the distances, bearings or elevations of distant objects.
Survey bench marks were established so the location of every excavation trench as well as of all uncovered features and recovered artifacts could be precisely recorded with the use of the tachymeters.
The measurements are performed with modern surveying techniques, such as self-registering tachymeters and GPS receivers.
The use of contact-less and satellite-based tachymeters and digital levelling instruments guarantees a standardised and efficient workflow.
A system for alignment and measurement of positions includes an electronic tachymeter and a reflector system.
2A facility on a watch for measuring speed.
转速计
Example sentencesExamples
Two new Carrera tachymeters were launched at the end of 2005: a model with chocolate-brown dial, tachymeter and bracelet; and a model with blue dial and tachymeter and steel bracelet.
Unlike paintings, for example, which can be judged instinctively, if subjectively, a watch has to be judged from both an aesthetic and a mechanical standpoint, with a complicated lexicon of bezels, tourbillons and tachymeters to master beside the issue of aesthetics.
Derivatives
tachymetric
adjective
A tachymetric plan and 3D model of the measured and geophysically prospected areas was created.
Example sentencesExamples
The invention relates to a staking out device with a stake that can be planted on a target point in the vicinity of a point to be staked out, a reflector mounted on said stake for the tachymetric detection of the target point, and a unit provided on the stake for sending and receiving information to or from a tachymeter.
The timepiece features tachymetric divisions in aluminum, protective pushbuttons with notches for comfort of operating, and a screw-in crown.
The chronograph hour counter was not running properly, the movement needed a complete overhaul, the case and bracelet were marred with dings and scuffs, the gold caps on the crown and pushers were all worn through and, most significantly, the signature gold bezel with burgundy tachymetric insert was chipped and dented.
This module provides an introduction to cartography and covers the production of topographic maps and plans based on accurate tachymetric surveys using computer aided drafting packages.
