Sensor box containing three SEIKA sensors and three signal conditioners with 4...20mA output
The SBG3I is a
pressure die cast aluminium sensor housing (IP65) with two
integrated sensors for measuring accelerations and/or
inclinations along three axis acceleration and/or two axis
As well as the sensors, the box contains three independent signal conditioners, each with a 4...20mA, 2-wire output, and three separate, highly stable voltage supply feeding off the corresponding current loop, one for each sensor. Furthermore, each 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 connection to the current loop. Interference signals caused by unwanted ground currents are eliminated by electrically isolating each sensor and signal conditioner from each other and the housing.
A special electronic temperature compensation system can significantly reduce the temperature sensitivity of the implemented sensors. The compact PG cable gland and compact housing size in combination with the 3-wire connection enable the use of this high quality measuring system in harsh operating conditions.
The SBG3I is suitable for applications requiring precise acceleration or inclination measurements along three axis under harsh circumstances and returning of a 4...20mA 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.
