The SB2i sensor box is packaged in a solid and compact pressure-cast aluminum housing with two integrated sensors for dual axis inclination or acceleration measurements.
Within the box are 2 amplifier sections, each with 4…20mA output signal, which allows for two separate 2-wire systems; and a separate highly stable power supply for the sensor. The amplifiers contain a low-pass filter for upper frequency limitation, with noise suppression filtering and a diode bridge for the unipolar current-loop operation. Both sensor and amplifier are galvanically isolated from the housing - further reducing susceptibility to outside noise. Specific response time constants and maximum current output limitations are additional options.
For a higher degree of accuracy and a considerably reduced temperature drift over the entire operating temperature range, the SB2i box is optimized with special temperature compensation. Add a strong metal PG cable fixing combined with the 2-wire current-loop output the SB2i provides a high-quality system for use under many types of harsh working conditions.
