SB1I 1-Axis with 4-20mA Output

Measurement Environment: One Axis, 4~20mA output
Applications: Sensor box (98 x 64 x 56mm3) with one integrated SEIKA sensor of any type and one integrated signal conditioner with 4…20mA output.

The SB1I is a pressure die cast aluminium sensor housing (IP65) with an integrated sensor for measuring uniaxial acceleration or inclination. In addition to the sensor, the box contains a signal conditioner with 4…20mA, 2-wire output and a separate, highly stable supply voltage feeding off the current loop. Furthermore, the 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 coupling to the current loop. Interference signals caused by unwanted ground currents are avoided by electrically isolating sensor and signal conditioner from the housing.
