| Acuity AR4000 rangefinder |
The AccuRange 4000 laser rangefinder is Acuity's longest distance
measuring tool. Employing time-of-flight measuring principles, the
rangefinder can accurately gage distances up to 54 feet (16.45 m).
Non-contact measurement is made simple with the three models within
the AR4000 rangefinder series. All models are compact and durable,
residing in a NEMA-4 enclosure for challenging industrial environments.
The AR4000-LIR laser rangefinder has a working range to 54 feet
on light surfaces (85% diffuse reflectance, such as paper or light
paint) or 35 feet on a 30% reflectance target with an accuracy of
0.1 inches. It uses an infrared 780 nm 8 milliwatt laser. This is
the sensor of choice for best accuracy in most applications. An
optional 20 mW laser upgrades is also available for the AR4000-LIR
sensor with an accuracy of 0.2 inches, for extended range to darker
surfaces (54 feet on 30% reflectance) and in sunlight.
The AR4000-LV rangefinder has a working range of zero to 40 feet
on 85% diffuse reflectance surfaces or 30 feet on a 30% reflectance
target with an accuracy of 0.3 inches. It uses a visible 670 nm
5 milliwatt laser. This is the sensor of choice where a visible
beam spot is required or your application must remain under and
FDA Class IIIb laser category.
The AR4000-RET distance measuring rangefinder is used with reflective
tape supplied with the sensor. It is a low-power, Class I eye-safe
device, with an accuracy of 0.1 inches with a range of 1.5 to 54
feet. This is the sensor of choice where it is possible to apply
the adhesive-backed retroreflective tape to the target surface,
since this provides a strong return signal for optimum operation.
