SMi™ Stepper motor gauges use a small electronic motor that only
turns a tiny fraction of a rotation to drive the pointer. It is
electronically controlled and is much more precise than the
traditional mechanical instruments whose accuracy can be affected
by many factors. Many professional race teams -NASCAR™,
etc. – are switching to this style of gauge for the improved
the in-car cameras). Approved for use
Built-in Warning Lights – Ultra Bright 2 Stage
2 set points are easily adjusted to your needs (critical oil
pressure has 3 set points). For example set water temp for just
above normal running temp (if you run 215° set it at 230°). Above
that the LED comes on to let you know the motor is starting to get
warm. Set the second one at the max temp your engine can tolerate
(say 250°). At this point the LED flashes to attract your
attention, possibly saving motor damage.
Since oil pressure is so critical it has 3 set
You can set the first just below normal running pressure (say
normal is 60 psi – set it at 50 psi – no damage there). At this
point the LED comes on. Set the second at 35 psi. The LED flashes –
you need to know here, possible damage. Set the third at 20 psi.
Engine damage is likely here. At this third set point the LED
continues to flash PLUS
the gauge backlight starts to flash. It’s hard to
miss this – day or night. It allows you to get the engine shut down
before it blows up, saving you $$.
NOTE: These electronic gauges are not intended to be waterproof.
Cover the gauges if the car interior is to be washed down.
