Seika SBL1S Sensor Box

SBL1S Sensor box

Sensor box for use in particularly harsh operating conditions containing two sensors, one signal conditioner with 4 – 20mA output, one signal conditioner with 0 – 5V output and two safety relays for threshold monitoring.

The SBL1S is a pressure die cast aluminium housing (IP65) with two integrated sensors for uniaxial measurement of inclinations.
In addition to the sensors, the housing contains one signal conditioner with 4 – 20mA output and one signal conditioner with 0 – 5V output. These include active low pass filters, whose upper cut-off frequencies / settling times can be adjusted to fit the measuring task, and noise voltage filters to ensure the EMC. Interference signals caused by undefined ground currents are eliminated by electrically isolating sensors and signal conditioners from each other and the housing.
The voltage output of the SBL1S has two switch outputs, each with a safety relay. Two helical potentiometers allow the setting of two trigger thresholds within the measuring range, at which the corresponding relay triggers. Each relay output has an independent opening and closing contact. The switching hysteresis can be adapted to the measurement task.
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 15-wire connection enable the use of this high quality measuring system in harsh operating conditions.

Features:

  • Large, robust pressure die cast aluminium housing (IP65)
  • Angular adjustable, vibration damped 3 point fastening of rigid, 3.2mm thick base PCB
  • All SEIKA sensors fit the housing and can be installed in different directions of operation
  • Two integrated, independent measuring channels, electrically isolated from each other and the housing and redundant if operating direction is the same

  • All SEIKA sensors fit the housing and can be installed in different directions of operation
  • Two integrated, independent measuring channels, electrically isolated from each other and the housing and redundant if operating direction is the same

Channel 1:

  • Signal conditioner with 4-10mA, 2-wire output
  • Temperature drift compensation
  • No separate supply voltage necessary
  • Either connection polarity

Channel 2:

  • Signal conditioner with 0-5V output
  • Temperature drift compensation
  • 12 to 24V supply voltage
  • Either connection polarity
  • Two separate, individually adjustable safety relay outputs with a separate open and a separate close mechanism each

Both Channels:

  • Output signals calibrated to customer’s specifications
  • Extensive EMC protection
  • Highly stable sensor supply voltage
  • High mechanical overload resistance
  • Low pass filter with optional choice of cut-off frequency for suppression of interference frequencies
