The SB1U is a pressure die cast aluminium sensor housing (IP65) with an integrated sensor for measuring uniaxial acceleration or inclination.

As well as the sensor, the box contains a signal conditioner with 0 ... 5V output and a separate, highly stable supply voltage that can be used externally as a reference point. Furthermore, the signal conditioner includes an active low pass filter, whose upper cut-off frequency / settling time can be adjusted to suit the measurement task, and a noise voltage filter to guarantee the EMC. Interference signals caused by unwanted ground currents are eliminated by electrically isolating sensor and signal conditioner from the housing.

Unlike the SB2.., the SB1U can accommodate larger inclinometers, such as the NG.. series, that have a higher measuring accuracy. A special electronic temperature compensation system can significantly reduce the temperature sensitivity of the implemented sensor.

The compact PG metal cable gland and small housing size in combination with the max.5-wire connection enable the use of this high quality measuring system in harsh operating conditions.


The SB1U is suitable for applications requiring precise inclination or acceleration measurements under harsh circumstances and returning of a 0 ... 5V output signal. Areas of successful implementation include construction, mining, agricultural machinery, transportation and conveyor systems, ships, operation and automation technology as well as general mechanical engineering.
