DL-500 Digital Levels Simplify levelling tasks and increase productivity

The new Topcon DL-500 range of digital levels is the ideal choice for any elevation determination based tasks, whether that’s simple line levelling, traverse station height measurement for control networks or more high precision work such as deformation monitoring, railway construction or high order levelling runs. Two models are available, offering different levels of accuracy. The DL-502 is capable of measuring to an accuracy of 0.6mm to an RAB bar-coded Invar staff, and 1mm to a glass-fibre version, whilst the DL-503 can measure to 1.5mm to a bar-coded glass-fibre staff. In addition, both models are capable of carrying out horizontal distance measurements to the bar code staves. Such observations have a measurement range of 1.6m to 100m and are accurate to 0.1% of the distance below 50m.

The user interface is supplied by a colour LCD screen which incorparates a easy to navigate menu structure manipulated by a simple keypad. The DL-500s are supplied with an internal memory which enables the recording of up to 2000 data points. Alternatively, the DL-500 can be used in conjunction with a FC-250 or FC-2500 field controller to integrate all height measurements within your current TopSURV project. Supplied with a 7.2v Li-Ion battery, the digital levels are capable of an incredible 16 hours continuous operating time. Once you levelling work has been completed, the data can be downloaded using the standard RS232C interface to you PC and data can be viewed in TopconLink or processed and adjusted using TopconTools.

Staff Attitude

Accurate Measurements

Thanks to new bar-code staff technology in conjuction with powerful processing algorithms, the DL-502 and DL-503 digital levels have many new innovative features to increase job site productivity

Additionally, new and improved algorithms within the processing unit of the instruments have been developed to allow the DL-500’s CCD to recognise and process the bar code pattern on a staff that is being rocked backwards and forwards in line with the level’s line of sight.

Using the exclusive pattern on the new RAB (Random Bi-directional) means that the attitude of the staff is now automatically detected. No longer will it be possible to measure and log erroneous backsight or foresight entries due to observations being taken to inverted staff positions. The DL500s will decode the observed staff pattern and automatically process whether it is an upright or inverted point.

This tried and trusted traditional levelling technique has always meant that the lowest possible staff reading is viewed by the observor… And now this same technique is possible for the very first time with a digital level, allowing for the most accurate readings to be measured and logged.
