Total stations are optical measuring tools that are widely used in construction, land surveying, mining and engineering for topographic mapping and layout work.
A reflector-less total station features a laser measurement unit, which emits a focused laser beam or infrared signal toward a target surface. The beam reflects off the surface back to the instrument's receiver, and the distance is calculated based on the time-of-flight (TOF) of the signal.
Vertical and horizontal angles are measured using precision encoders. By using distance and angle data, the instrument can calculate specific 3D coordinates of the target point using trigonometry. Some systems can capture and stream video, as well as taking panoramic photos. Today’s latest total stations include software for recording and processing measurements, which enables direct transfer of data to computers or design software.
Reflector-less technology is more efficient for surveying tasks in remote or challenging environments. Reflector-less total stations do not need to set up reflectors or prisms, which saves time during surveying. For this reason, they are the preferred tool for surveying busy roads or hazardous areas.
Total stations reduce manual focus time and they minimize the chance of errors. HKP’s Actuators bring auto focus capabilities to total stations by quickly and accurately controlling the A to B movements in the device. HKP’s coarse lead screw actuator provides lightning-fast response times, to deliver optimal accuracy.
Application Challenges (Pros and Cons):
- Compact size and high accuracy & stability
- Anti-backlash nut design and special mounting method to combine with customer structure
- Customized testing parameters and setting ups
- Delicate packing
Typical Current Motion Solutions:
LE15 series motor
The HKP 15000 Series is a 15mm stepper motor linear actuator that is available in two designs – captive and external linear versions, and it is also available in a variety of resolutions that range from 0.02mm to 0.10mm per step. The 15000 series can deliver force of up to 8 lbs (35N) without compromising reliability. Models can also be micro stepped for even finer resolution. For total station applications, this actuator is a popular choice because it can deliver precise remote controlled linear movements in a very small package.
A Growing list of users in Multiple Industries:
The functionality that is available in today’s reflector-less total stations continues to improve. As a result, the tools are widely used by a range of professionals, including: land surveyors, construction professionals, civil engineers, miners, archaeologists, architects, forensic investigators, environmental scientists and maintenance teams at utilities and other industries.
