J1939 - DEF Level Instrument

J1939 - DEF Level Instrument


This NexSysLink® stand-alone instrument directly interfaces to an SAE J1939 compliant CAN bus without the need for a Master Node Instrument or some other gateway device to display DEF (Diesel Exhaust Fluid) level.

The instrument employs advanced stepper motor technology that provides a full 250° pointer sweep. Standard features include LED illumination and an environmentally sealed connector. A large, bright LED alert indicator activates to provide visual warning when the DEF level is low.
