3-3/8" Speedometer
Item: 5352
Marshall in-dash speedometers come in 3-3/8" and 5" sizes and a variety of dial colors and bezel options.
Marshall speedometers feature two trip meters and an odometer (miles). Marshall speedometers come precalibrated for 16,000 pulses per mile and can be recalibrated at any time for 4,000 - 200,000 pulses per mile using the included trip/calibration button. Calibration is as easy as pressing the included calibration button and driving one measured mile.
Marshall electronic speedometers work with hall effect senders, GPS senders and magnetic pickup sensors (VSS). Any speed sender or electronic module that meets the following conditions can be used with our speedo:
- Pulse range generated proportional to the vehicle speed
- Signal with minimum 3V peak to peak signal - typical for 3-wire hall effect and 2 wire vehicle speed sensor outputs
- 4000-200,000 pulses per mile (16,000 is typical).
