SB2I Sensor Box

SB2I Sensor Box

Model: SB2I

Measurement Environment: Two Axis, 4~20mA output

Applications: Sensor box (98 x 64 x 56mm3) with two integrated SEIKA sensors of type B, BD, BDK, N or NB and two integrated signal conditioners with a 4...20mA output each. Both channels are electrically isolated from each other.

This is just one example of the Seika accelerometers sensor boxes we have available at Sensors UK. Please contact us to discuss the wider options available.

The SB2I is a pressure die cast aluminium sensor housing (IP65) with two integrated sensors for measuring inclinations and/or accelerations along two axis. As well as the sensors, the box contains two independent signal conditioners, each with a 4...20mA, 2- wire output, and two 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 small housing size in combination with the 3-wire connection enable the use of this high quality measuring system in harsh operating conditions.



The SB2I is suitable for applications requiring precise inclination or acceleration measurements along two 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.
