Operator Interfaces

Maxima’s instrumentation cover a wide range of "operator interfaces", from custom-engineered J1939/CAN instrument clusters and displays to standard gauges.

DATA-BUS GAUGES, TACHOMETERS, SPEEDOMETERS
Direct Data-Bus Instruments (DDBI™) provide a DIRECT connection to the SAE J1939/CAN bus network—no instrument controller or “gateway” required. The result? Lower installed-system cost and fewer things-to-go-wrong.

Choose from a full line of instruments, including tachs and speedos, with or without displays. Tachs and speedos display diagnostics information such as fault codes.

Also available: Matching electric gauges for non-bus functions such as fuel level and brake pressure, a mechanical 3-3/8” dual air pressure gauge (Stewart Warner PDF here; Datcon PDF here) and 2” DDBI™ speedometer.

DDBI™ is the perfect solution for military vehicle applications.  Recently, our instruments were tested by TACOM for 96,000 hours WITH NO FAILURES, even when subjected to 100 V/m as an installed-system for vehicle-level radiated immunity.  Now that's severe-duty!
