The REDAM LDM series has been specifically developed for connection to LDM series LASER distance meters, allowing real-time display of the measurement taken by the LASER distance meter. <\/p>\n\n

The measurement is shown on a giant display, visible even from a great distance, or transmitted to remote terminals via Wi-Fi or Ethernet networks.<\/p>\n\n

All the measurements displayed can be compared with tolerance thresholds so as to generate alarms in the event of out-of-tolerance values when certain thresholds are exceeded, or visual signals that guide the operator through any adjustment operations (a red value indicates out of tolerance, a yellow value indicates a warning, a green value means the measurement is acceptable). <\/p>\n\n

                  Measurement and control of the position, deformation and vibration of large structures, or of structures located at very long distances. <\/strong> <\/h3>\n\n\n\n

                  The ability to work on very different surfaces, or with very large variations in colour and reflectivity, makes it possible to measure distance, position and oscillation even on objects that differ greatly from one another.<\/p>\n\n\n\n

                  The use of intelligent data loggers allows constant, continuous monitoring even over observation periods of weeks or months. <\/p>\n\n\n\n

                  Remote data transmission also allows several measuring points or several structures to be monitored from a single observation and control point. <\/p>\n<\/div><\/div>\n<\/div>\n<\/div>\n\n

                    More about LASER rangefinders<\/h2>\n\n

                    The LDM family of LASER rangefinders consists of a range of optoelectronic distance measuring devices for industrial applications, with an analog (4 mA to 20 mA) or digital (Ethernet, Profinet, Profibus, RS232, RS422) interface.<\/p>\n\n

                    LDM series LASER rangefinders are used for the precise measurement of distances<\/strong> from a few meters up to three kilometers. Distance measurement is an established application<\/strong> of laser technology. <\/p>\n\n

                    These optical sensors use LASER light (pulsed or modulated) to measure distance, height, length, level and position in a non-contact process. To achieve this, all the components work together in a perfectly coordinated overall system. <\/p>\n\n

                    Measuring principle<\/h4>\n\n

                    LASER distance meters consist of a laser emitter, a transmitting and receiving optical system, photosensitive semiconductors and sophisticated electronics with algorithms for time measurement or phase measurement.<\/p>\n\n

                    Various optoelectronic principles are used to determine the measurement, such as time of flight, phase comparison and LASER pulse with back-mixing. These different methods allow individual measurements accurate to the millimetre<\/strong> and measuring ranges of up to several hundred metres. <\/p>\n\n

                    Reliable and precise measurements<\/h3>\n\n

                    Using LASER distance meters it is possible to measure on natural surfaces<\/strong> or on special reflectors, obtaining fast and precise results. <\/p>\n\n

                    The LASER distance meters offered by RODER use visible or invisible optical radiation and are classified, in accordance with current regulations, as class 1 or 2 (classes that are safe to operate even without protective eyewear).<\/p>\n\n

                    The compact design allows easy installation of the LASER distance meter even where space is limited or in industrial applications. <\/p>\n\n

                    All devices offer standard interfaces, analogue or digital data output and configurable switching outputs. The LDM family of LASER distance meters is widely used for industrial applications with an analogue (4 – 20 mA) or digital interface (Ethernet, Profinet, Profibus, RS232, RS422, SSI<\/em>). <\/p>\n\n

                    With the REDAM-LDM family of remote displays it is also possible to monitor processes with multi-point sensors and a multi-sensor acquisition network. <\/p>\n\n
