Mechanical gauges sense pressure or temperature through tubing that transmits the pressure, vacuum or temperature to the gauge. Electrical power is required for operation of night lighting only. All of these mechanical gauges have a 270° sweep and have water resistant lenses made from glass, not plastic, so they are scratch resistant.
