Sokkia SRX Reflectorless Motorised Total StationSokkia SRX Robotic Total StationsThe SRX is the next generation of motorized Sokkia total stations for all surveying, robotic and monitoring applications. You don't have to look further. The SRX, a new line-up of superb robotic total stations featuring the latest technology for accurate positioning. The technology has been developed to give surveyors the utmost confidence. Its flawless operational processes enable the instrument to search easily, lock, track and precisely aim to the required position. Benefits The SRX has many beneficial features which include: Bluetooth® wireless technology for reliable cable-free communication, the superb new RED-tech EX 500 meter reflectorless phase shift distance measuring meter, digital encoder driven servo's, unique on-demand search technology, auto-pointing on prisms and reflective sheets, multiple USB ports, a CF card slot for easy data transfer, a trigger key for fast measuring, a large fully illuminated keyboard, full colour touch screen display and the Windows CE operating system. There are a number of different versions of the SRX available with an accuracy varying from 1" to 5" that allow the SRX to be used in a wide range of positioning applications. Work with confidence To work in single-man setup, the surveyor will only work from the prism side with full confidence. The pole is equipped with a miniature omni-directional prism, a robust controller, a communication unit and a rubber bumper to protect the prism from damage should it fall accidentally. The unique on-demand search technology ensures that communication between the SRX and the surveyor is guaranteed, loosing line-of-sight is no longer a problem. You simply pick up the SRX anytime you want, the instrument doesn't necessarily have to follow. The remote controller features all software applications needed to do you're surveying job. The SRX is equipped with the most comprehensive software on-board for any application that requires a surveyor behind the instrument. The dramatically improved RED-tech EX EDM Distance meter featuring its superior phase shift technology contributes further to optimum performance for the surveyor. Reflectorless measurements, even in the most difficult situations and positions, are unsurpassed within the typical reflectorless working range between 30cm and 500m. With these features, the SRX is expected to become a trendsetter for positioning in industrial and monitoring applications. The power of Sokkia's RED-tech EX distance meter The RED-tech EX is Sokkia's drastically improved Revolutionary Digital processing Technology: a revolution in the field of measuring distances; the result of continuing, smart developments by Sokkia's R&D team in Japan. RED-tech EX, the third generation of RED-Tech distance meters, offers greater speed, accuracy and range. It undoubtedly sets the trend for further generations of precision electronic distance meters. Almost all of Sokkia's total stations are equipped with the RED-tech electronic distance meters (EDM) which enables them to make accurate distance measurements. But what exactly is so revolutionary about RED-tech EX? The phase-shift and pulse methods are commonly used in the geodesy field for taking measurements without using reflectors. RED-tech EX, Sokkia's revolutionary digital signal processing technology, uses a unique procedure to analyze four light waves at the same time. The on-board processor continually compares thousands of measurements in real-time with the recurring data that has been processed. In doing this it checks and locates wave discrepancies such as interference that cannot be filtered out (atmospheric conditions) and temporary obstacles (cars, leaves etc). This means that only the pure, unadulterated actual signal that has been returned is used for calculating the waves' exact phase shift. This phase shift ultimately gives the exact correction which enables the optimum distance measurement value to be calculated. The intelligent RED-tech EX processor is able to learn how to execute increasingly accurate, repetitive measurements by itself. By using this combination of digital processing and phase shift algorithms technology, Sokkia total stations quite simply achieve the best performance in terms of accuracy, repeatability and reliability within the target range of 30 cm to 500 meters. The difference using RED-tech EX) Pulse EDM's emit a concentrated, short pulse of high density laser light and a built-in clock measures the "time of flight". The longer the light travels the better the time difference between emitting and receiving can be determent. The downside of this technology is encountered when measuring distances less than 50 meters since the clock simply cannot measure the time difference accurately enough due to the extremely short "time of flight". This means that it is not a problem to measure extreme distances up to 2000 meters for example. Whether or not this is a positive sales point is open to question since no one wants to measure an object that far away due to the difficulty of aiming accurately and capturing the returned signal. Phase shift does not use a clock so it is easily possible to measure objects just 30 cm from the EDM. This is a definite advantage compared with the pulse method. By far the majority of reflectorless measurements are made to objects within a range of 200 meters; but RED-Tech EX reaches 500 meters just to be absolutely sure. The phase shift measurement spot is also much smaller than the pulse diameter. This enables very small objects such as power lines, the corners of buildings, manholes etc. to be measured even if obstacles such as leaves or fences are in the way. The most important feature is that the accuracy of phase shift EDM's is greater than any other type of EDM. Safety Phase shift technology has to emit a continuous laser beam and this has the positive result of producing a continuous stream of data. In order to achieve accurate results high output power is needed. This is often regarded as being hazardous, which is true when it contacts the human eye. However, the human eye has a reflex speed of 0.1 seconds which makes it safe to use. The alternative EDM's are not visible. These pulse lasers will also damage eyes over a long period of exposure but because they are invisible the human eye will not react and so could be damaged. Since the pulse method uses invisible light, the manufacturers of this type of equipment embed an extra laser which functions as a laser pointer. The possibility exists that this laser pointer may not be aligned with the EDM. If this should be the case, the distance data will be derived from a different position to the one that the pointer is targeting. This error is simply impossible with our RED-Tech EX since the EDM laser is used for both the pointer and distance measurement functions. SOKKIA, founded in 1920 in Japan, is a leading manufacturer in developing complete measurement solutions for surveying, construction and industrial measurement applications. Our portfolio includes GNSS systems (Global Navigation Satellite Systems), reflectorless and robotic total stations, automated 3-D stations, digital theodolites, automatic/digital levels, rotation/line lasers and software.
