L) cable length is dependent upon the instrument to which the sensor is connected. Consult the instrument

manual for details.

• Connect the 2350 cable directly to

Digital (S

• When the 2350 includes a junction

box, connect the 2350 terminals to any
Digital (S

• When the 2350 includes a junction box, connect the 2350

terminals to a loop device as shown.

5. 4 to 20 mA Loop Wiring

• The 2350-3 provides a 4 to 20 mA loop output when powered with 24 VDC.
• Connecting the SHIELD to a direct Earth ground may reduce electrical noise interference.
• Red wire is not used, do not remove the heat shrink. See Section 6, 4 to 20 mA Span Adjustment.
