R1000 Distance Sensors
The exact positioning of stock feeders, moving carriages, cranes, and handling machines, as
well as the performance of length measurements in the woodworking industry, for concrete
saws, and in elevator construction, requires distance sensors that are capable of returning
measured values at a high measurement rate over large distances with millimeter precision.
Distance sensors are used wherever straight-line distances need to be determined precisely
and reliably.
Optoelectronic distance sensors are almost wear-free and are easy to install.
Additional benefits offered by these devices are short assembly and commissioning times and
the high degree of reliability of a photoelectric measuring system, as well as ease of replace-
ment.
The available interface is:
•
SSI (Synchronous Serial Interface)
The photoelectric sensors of the R1000 series meet the safety requirements of laser class 1
(EN 60825). The low amount of laser light emitted ensures that operating personnel are not
injured or harmed.

Function Principle
The devices work according to the principle of pulse ranging technology (PRT). The device
measures the time between sending a light pulse and receiving the reflected pulse. Due to the
constancy of the speed of light, this time is a measurement of distance.
The light source and light receiver are located in the device. A reflector is required for measur-
ing the distance, and must be installed opposite the device. By virtue of its technical features,
Pulse Ranging Technology (PRT) is particularly well-suited for high-precision distance mea-
surement over large distances compared to other methods of distance measurement.
In comparison to other distance measurement processes, time-of-flight measurement is largely
independent of the measuring environment, and can therefore be used to a high degree of
accuracy in harsh everyday industrial conditions.
Note
Influence of Ambient Conditions
The speed of light depends on the air temperature and barometric pressure.
The influence of the air temperature amounts to 1 ppm/K.
The influence of barometric pressure amounts to -0.3 ppm/hPa.
The user must take these factors into consideration when measuring long distances.
