Description
The SB2U is a pressure die cast aluminium housing (IP67) with two integrated sensors for biaxial inclination and acceleration measurements.
In addition, the sensorbox contains two amplifiers, each with a 0.5 ... 4.5 Volt signal output and a highly stable supply voltage that can be used externally as a reference. Each amplifier contains an active low-pass filter, whose upper cut-off frequency or settling time constant can be adapted to the measurement task, as well as noise voltage filters to ensure EMC. Sensors and amplifiers are galvanically separated from the housing to eliminate interference from unwanted ground currents. 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 compact metal cable gland and small size of the robust aluminium housing enable this high quality measuring system to be used under harsh operating conditions.
Application
The SB2U is suitable for applications requiring precise inclination or acceleration measurements along two axis under harsh circumstances and returning of a 0.5 to 4.5 Volt output signal each. Areas of successful implementation include construction, mining, agricultural machinery, transportation and conveyor systems, ships, operation and automation technology as well as general mechanical engineering.
