Seika SBL1 Sensor Box

SBL1 Sensor box

Sensor box for use in particularly harsh operating conditions containing one sensor and one signal conditioner with 4 – 20mA, 2-wire output.

The SBL1 is a large, pressure die cast aluminium housing (IP65) with an integrated sensor for uniaxial inclination measurements.
In addition to the sensor, the box contains a signal conditioner with a 4 – 20mA, 2-wire output and a separate, highly stable supply voltage for the actual sensor 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, noise voltage filters and a diode bridge for unipolar connection to the current loop. Interference signals caused by unwanted ground currents are eliminated by electrically isolating sensor and signal conditioner from the housing.
Unlike the SB2I sensor box, the SBL1 can accommodate larger inclinometers, such as the NG series inclinometer, that have a higher measuring accuracy. A special electronic temperature compensation system can significantly reduce the temperature sensitivity of the implemented sensor.
The compact PG cable gland and compact housing size in combination with the 2-wire connection enable the use of this high quality measuring system in harsh operating conditions.
