What is the difference between ISSPRO's EV Series and the new EV² gauges? EV² is ISSPRO's new standalone stepper motor gauge series. The EV series is ISSPRO's economy line of air core gauges. There are a number of advantages to the EV² versus the EV series gauges. They are similar in appearance (available in the same general styles), but EV series uses curved lenses.
The EV series uses a separate "amplifier box" near the gauge head, so you need to find a mounting spot for it. The amplifier box for a pyrometer measures about 2.3" x 2.3" x 1.6", and for a temperature gauge it measures about 2.75" x 2.4" x 0.88". The EV series is an air core gauge movement, basically a set of electric windings, with electronics in the amplifier box to drive them. They also use conventional incandescent bulbs for lighting, although we offer LED replacement bulbs in a variety of colors so you are able to change the backlighting colors. The EV series does include mechanical boost and other pressure gauges. These are typically lower cost than electronic gauges, but require running tubing into the cab. In the case of a fuel pressure gauge, it requires the use of an isolator to keep fuel out of the cab.
The EV² Series is completely "standalone", no amplifier box needed. They utilize stepper motor movements for precision, and LED backlighting for brightness and durability. Both of these technologies allow the gauge to operate at a very low current draw (less than 0.1 Amp with lights at full brightness). Also, the backlighting is powered by the main ignition input, without drawing any measurable current from the dimmer circuit of the vehicle, so there is no worry about overloading the factory dimmer.
