Description
The NG360 is a capacitive, liquid based inclinometer with integrated sensor electronics and 16 bit microprocessor. The measurement result is tran***itted via a RS485 port for further processing. Up to 78 sensors can be operated using a single communicati*** line.
The measurement method provides a linear relati***hip between the angle to be measured and the output signal. The determined angle is independent of the local gr***itational acceleration, that means that no matter where the measurement is being taken, whether in Europe, Australia, on Mount Everest or on the moon, the inclination will be measured correctly anywhere. Temperature related inaccuracies are corrected by the integrated microprocessor.
Application
The NG360 inclinometer is suitable for applicati*** requiring the measurement of any angle for further processing on a PC.
Typical areas of application include c***truction, mining, vehicles, aircraft, ships, surveying equipment, and transportation and conveyor systems.

Description
The SB1I is a pressure die cast aluminium sensor housing (IP65) with an integrated sensor for measuring uniaxial acceleration or inclination.
In addition to the sensor, the box contains a signal conditioner with 4...20mA, 2-wire output and a separate, highly stable supply voltage feeding off the current loop. 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, an output stage with current limitation, a noise voltage filter and a diode bridge for unipolar coupling to the current loop. Interference signals caused by unwanted ground currents are ***oided by electrically isolating sensor and signal conditioner from the housing. Unlike the SB2.., the SB1I can accommodate larger inclinometers, such as the NG-series, that h***e a higher measuring accuracy. A special electronic temperature compensation system can significantly reduce the temperature sensitivity of the implemented sensor.
The compact metal cable guide and ***all housing size in combination with the 2-wire connection enable the use of this high quality measuring system in harsh operating conditi***.
Application
The SB1I is suitable for applicati*** requiring precise inclination or acceleration measurements under harsh circumstances and returning of a 4...20mA output signal. Areas of successful implementation include c***truction, mining, agricultural machinery, transportation and conveyor systems, ships, operation and automation technology as well as general mechanical engineering.
