Description
The sensorbox SBG3U is a pressure die cast aluminium housing (IP67) with three integrated sensors for measuring accelerations and/or inclinations along three axes.
In addition to the sensors, the sensorbox contains three independent voltage signal conditioners, providing a 0.5V ... 4.5V or (optionally) ±3.5 Volt output. Furthermore, each conditioner includes an active low pass filter, whose upper cut-off frequency / setting time can be adjusted to suit the measurement task. Sensors and amplifiers are electrically isolated from each other and from the housing. Electronic temperature compensation largely compensates for the temperature drift of the implemented sensors' sensitivity. Optionally, the temperature drift of both offset and sensitivity can be reduced significantly through individual compensation.
The robust metal cable gland and compact housing size allow the use of this high quality measurement systems in harsh operating conditions.
Application
The SBG3U is suitable for applications requiring precise acceleration or inclination measurements along three axes under harsh environment conditions. Typical areas of application include construction, mining and agricultural machinery, transportation and conveyor systems, ships, automation technology as well as general mechanical engineering.
