| NG2I, NG3I, NG4I Inclinometers of high measurement accuracy with an integrated 4...20mA signal conditioner for inclination measurement in the ranges of ±10, ±30 and ±80 degrees |
Features
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.
