Introduction
CTC junction box solutions allow for the monitoring of remotely mounted vibration
sensors, which would be otherwise restricted to human access due to safety
considerations .
SB282 Series Switch Box Overview
The SB282 stainless steel slope top switch box is used to convert the three-
conductor wiring of up to 8 remotely installed dual output sensors to two
switched BNC connectors and one output switched two-pin MIL spec connector
for portable data collection . BNC labeled “J1” and the two-pin MIL provide
output for vibration and the BNC labeled “J2” provides output for temperature
measurements . Input wiring from each sensor is connected via quick-connect or
screw terminal blocks . Each terminal block includes input for signal, temperature,
common and shield . The shield drain wire is earth-grounded via a ground stud
that is mounted to the side of the stainless steel enclosure . Optionally, the SB282
can be equipped with a multi-pin connector for interface with online systems for
continuous live readings . This connection requires a JB905-1A or -2A plug .
A centrally located switch on the enclosure’s panel board determines which
sensor provides output to each BNC and the two-pin MIL connector . A
measurement location card is located on the inside of the enclosure door to
identify each channel .
Rated for NEMA 4X (IP66), the SB282 can withstand harsh environments including
temperatures ranging from -58° to 180°F (-50° to 82°C) . The box is also resistant
to hose directed fluid and corrosion . A locking latch is installed on the door
allowing the box to be sealed from the elements when not in use .
