Seika SB1I Sensor Box

SB1I Sensor Box

Sensor box containing one sensor and one signal condtioner with 4 – 20mA, 2-wire 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. Unlike the SB2I sensor box, the SB1I 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 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.

  • Robust pressure die cast aluminium housing (IP65) with saltwater proof coating
  • Twist free 4-point fastening of rigid, 3.2 mm thick base PCB
  • Integrated signal conditioner with 4-20mA, 2-wire output
