SEIKA SB1I

The SB1I is a die cast aluminum sensor housing (IP65) with an integrated sensor for measuring uniaxial inclination.

The SB1I accommodates inclinometers, such as the NG-series SEIKA inclinometers, that have a higher measuring accuracy.

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 the sensor and signal conditioner from the housing. A special electronic temperature compensation system can significantly reduce the temperature sensitivity of the implemented sensor. The compact metal cable gland and small housing size in combination with the 2-wire connection enable the use of this high-quality measuring system in harsh operating conditions.

When ordering specify the Seika inclinometer type: Eg: NG3I-SB1I
