Description
The NG2I, NG3I and NG4I are capacitive and liquid based inclinometers with integrated sensor electronics and current amplifier. Electronic temperature compensation makes up for the temperature drift of the sensitivity of the primary transformer. An integrated, highly stable voltage regulator ensures stable operation for a range of supply voltages.
The measurement technique provides a linear relationship between the angle to be measured (up to 80 degrees for the NG4I) and the output signal that is calibrated during manufacture. The measuring time constant can be matched to the requirements of the measurement task by appropriate hardware programming.
The power is obtained from the measurement current loop, thereby eliminating the need for a separate power supply and enabling operation with two wire connection.
Application
The NG2I, NG3I and NG4I are suitable for applications requiring high measurement accuracy with high linearity and temperature stability as well as high long-term stability for measurement of large inclination angles and for which the power is to be supplied via a 4...20mA current loop without the need for a separate supply voltage.
We recommend the sensor box SB1I with an integrated NG - inclinometer and a 4...20mA output signal for operation in especially harsh operating conditions.
These inclinometers are typically used in construction, mining, vehicles, aircraft, ships, transportation and conveyor systems and process control as well as for safety engineering.
