Application Sample: BM2

Application: To use the Bargraph Meter model to indicate the throttle position of a motor vehicle.

The BM-HIGH model with a box is used to indicate the throttle position of a motor vehicle. The meter gives a good indication of where the throttle is at. The fuel consumption can be reduces slightly to get better mileage by reducing the throttle by a small amount while maintaining the same speed.
The display looks very nice at night or when covered from ambient light.

Figure 1. Display mounted in vehicle

The meter is mounted on the dash of a car. It is recommended to mount the display away from sunlight or bright light as it is hard to read the display. A voltage is tapped from the throttle position sensor with an output of 0-5V. The meter is then setup to display the voltage of the sensor at full throttle.
