| NTS-360 | NTS-360L | NTS-362R10 |
Angle measurement principle | Grating disk goniometer, need two plates, silicon photovoltaic cells as a receiver, you need to initialize | Angle measurement of absolute encoder disk, a disk, using CCD as the receiver, a simpler, more stable, and good maintenance, no need to initialize | NTS-360R10 is the same, only the light emitting tube using visible red laser tube, visible light-emitting tube power 10mw, intuitive, free prism the odometry 1000 meters |
Ranging principle | GaAs light emitting diode, the emission angle, left emission, and the right receiver, the reception area smaller | Infrared laser tube, small emission angle, collimated good point emission surface receiving receiving storage area |
Ranging time | The 3 seconds ACCUTLOG, tracking one second | Precision measurement 1 second, the track 0.5 seconds |
Measuring tape | 15MHz, the ACCUTLOG feet long, 10 meters, Of three measuring tape (transmitter frequency) | 60MHzAndPrecision measurement feet 2.5 meters long, more precisely, a total of five measuring tape (emission frequency of 5) |
Odometry | Single prism 2Km | Single prism 5Km |
Ranging circuit performance | Luminous tube power: 1mw Circuit magnification: a thousandfold Single motor dimmer Measured relative way: square-wave single-point sampling | Luminous tube power: 3mw Circuit magnification: 10,000 times Dynamic range dual-motor two dimmer: Measured relative way: sine wave multi-point sampling, more accurate |
The goniometer electronic compensator | Uniaxial liquid capacitive electronic compensation, only the vertical direction compensation, compensation stabilization time: 8 seconds | Biaxial optical electronic compensator can compensate for both vertical and horizontal directions, compensation stabilization time: 5 seconds to compensate for faster, more stable, higher precision |
Storage and the amount of storage | Memory: 10000 points | Memory: 10000 points SD Card: 1G (mass: 10 million points) |
Waterproof structure | Labyrinth waterproof structure, can prevent rain, Ingress Protection: IP33 grade | In various parts of waterproof rubber ring structure waterproof, waterproof, dustproof, moisture-proof. Ingress Protection: IP55 grade |
