SB2I Sensor box (98 x 64 x 56mm3) with two integrated SEIKA sensors of type B, BD, BDK, N or NB and two integrated signal conditioners with a 4...20mA output each. Both channels are electrically isolated from each other.
SB1U Sensor box (98 x 64 x 56mm3) with one integrated SEIKA sensor of any type and one integrated signal conditioner with 0...5V output.
SB1S Sensor box (98 x 64 x 56mm3) with one integrated SEIKA sensor of any type, one integrated signal conditioner with 0...5V output and two open collector switch outputs that respond to traversing of adjustable thresholds.
SBS1U Sensor box (98 x 64 x 56mm3) with one integrated SEIKA-Servo-Inclinometer for measuring small angles of up to 2 degrees with very high resolution and an integrated signal conditioner with 0...5V output.
SB360 Sensor box (98 x 64 x 56mm3) with one integrated SEIKA sensor of type NG360, internal microprocessor and RS485 interface.
SBG2U Sensor box (124 x 80 x 58mm3) with two integrated SEIKA sensors of type NG and two 0...5V outputs.
SBG3I Sensor box (124 x 80 x 58mm3) with three integrated SEIKA sensors and three integrated signal conditioners with 4...20mA output.
SBL1 Sensor box (180 x 180 x 100mm3 - large and robust) with one integrated SEIKA sensor of any type and one integrated signal conditioner with 4...20mA output.
SBL1S Sensor box (180 x 180 x 100mm3 - large and robust) with two integrated SEIKA sensors of any type, one integrated signal conditioner with 4...20mA output, one integrated signal conditioner with 0...5V output and two safety relays that respond to traversing of adjustable thresholds. The SBL1S has two redundant, electrically isolated measuring channels for safety related applications.
XB.. Extra robust, pressure-, saltwater- and corrosion-proof stainless steel sensor box (ø120 x 50) as an alternative to the SB.. housings (180 x 180 x 100mm3) for especially harsh operating conditions, aggressive fluids and saltwater.
