Prism-free performance comparison of three types of total stations

 NTS-362R

Angle measurement principle Grating disk angle measurement requires two disks, using silicon photocell as the receiver, need to be initialized Absolute encoder disk angle measurement, one disk, using CCD as the receiver, simpler, more stable, easy to maintain, no initialization and NTS -360L is the same, only the visible red laser tube is used for the luminous tube, the power of the luminous tube is 10mw, which is intuitively visible, and the prism-free measurement range is 300 meters

Ranging principle Adopting gallium arsenide light-emitting diodes, with larger emission angle, emitting on the left and receiving on the right, with a smaller receiving area. Infrared laser tube, small emission angle, good collimation, point emitting surface receiving, large receiving storage area

Ranging time: precise measurement 3 seconds, tracking 1 second precise measurement 1 second, tracking 0.5 second

Measuring ruler 15MHz, precision measuring ruler length 10 meters,

A total of three measuring rods (transmitting 3 frequencies) 60MHz, the precision measuring ruler is 2.5 meters long, more accurate, a total of five measuring rods (transmitting 5 frequencies)

Measuring range Single prism 2Km Single prism 5Km

Ranging circuit performance LED power: 1mw

Circuit magnification: 1 thousand times

Single motor dimming

Phase measurement method: square wave single point sampling LED power: 3mw

Circuit magnification: 10,000 times

Motor two-stage dimming: large dynamic range

Phase measurement method: multi-point sampling of sine wave, more accurate

Angle measuring electronic compensator Single-axis liquid capacitive electronic compensator, which can only compensate in the vertical direction, compensation stabilization time: 8 seconds Dual-axis photoelectric electronic compensator, can compensate in both vertical and horizontal directions, compensation stabilization time: 5 seconds, the compensation is faster, more stable, and more precise

Storage method and storage capacity Memory: 10,000 points Memory: 10,000 points

SD card: 1G (massive: 10 million points)

Waterproof structure The labyrinth-type waterproof structure is used to prevent rainwater.

Waterproof and dustproof grade: IP33 grade. The waterproof rubber ring structure is used in each part to waterproof, which can be waterproof, dustproof and moisture-proof. Waterproof and dustproof level: IP55 level
