The SM-1i-B is a pressure die cast aluminium sensor housing (IP67) with an integrated sensor for measuring uniaxial acceleration.
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.

The SM-1i-B can accommodate larger inclinometers, such as the SM-B, that have a higher measuring accuracy.
A special electronic temperature compensation system can significantly reduce the temperature sensitivity of the implemented sensor.

The compact metal cable guide and small housing size in combination with the 2-wire connection enable the use of this high quality measuring system in harsh operating conditions.
