Sensores de inclinación para nivelación láser y herramientas de construcción

Laser levels and construction tools, in general, are used for a variety of purposes in construction and surveying. Laser levels specifically are used to, you guessed it, make sure things are level, or off-level at a specific angle or grade. This could mean something as simple as hanging a picture in your home, or more complex and impactful like paving a road to a specific grade or making sure the floor of a building is flat. There are several types of laser levels including rotary lasers and line lasers, among others.

Piense en conducir su coche bajo la lluvia; ¿preferiría que la carretera tuviera agua acumulada para poder hacer un hidroavión, o preferiría que la carretera estuviera en un ángulo para que el agua corriera hacia un lado o hacia el otro, lo que haría que la conducción fuera más segura hasta su destino? Los niveles de láser suelen tener una precisión definida en ± mm/m o milímetros por metro, lo que significa el potencial error vertical en mm por cada metro de distancia, o:

¿Interesado en entender un % de grado vs. un ángulo en grados? Hay una variedad de conversiones que puedes hacer cuando conoces el % de grado (o pendiente), el ángulo de la pendiente (ver α), o la subida (ver Δh) y la carrera (ver d):

Aquí hay algunas otras áreas en las que se puede usar un nivel de láser:

Instalación de techos, gabinetes y estanterías, diseño de sitios de construcción, elevaciones de terreno (para construcción y riego agrícola), alineación de vallas, postes, cubiertas y mampostería.

Note that laser levels typically use very high accuracy tilt sensors in order to maintain precise measurements over long distances. Typical Fredericks sensors for these applications are the 0703-1602-99 for ±25° measurement with ±0.005° repeatability and the 0703-0711-99 for ±3° measurement with ±0.001° repeatability. Both of these are single-axis solutions, but two sensors can be mounted perpendicular for dual (2) axis measurement. As an example, let’s convert these repeatability specifications into mm/m measurements using the equations we talked about before:

This can also be compared with our wide range of tilt sensor solutions, which are a less accurate option but provide 2-axis measurement in a lower-cost package. For example, the 0717-4313-99 tilt sensor has a measurement range of ±60° with ±0.05° repeatability, which converts to the following accuracy in mm/m:

Note that these repeatabilities (also called accuracy) specifications typically can’t be achieved with low-cost MEMS solutions, or any other low-cost tilt measurement solutions, making electrolytic tilt sensors ideal for this application. Additionally, electrolytic tilt sensors have no moving parts so they don’t have any measurement properties that change over time or temperature. This means that they’re much more repeatable over time and temperature than other solutions. To learn more about electrolytic tilt sensors, check out this video:
