To make the driver to keep abreast of the work vehicle and the system, the dashboard of the car is equipped with a variety of cab indicating instrument and various alarm devices.
First, the speedometer and speed warning device
Speedometer indicates vehicle speed by the speed table and record over the distance traveled by car odometer composition, both mounted on a common shell, a shaft driven by the same.
Speedometer is the use of magnetic mutual inductance effect, so that the pointer on the dial and the pendulum angle is proportional to vehicle speed. In the case of the dial is equipped with a scale.
Odometer by the number of counts and the rotating drum unit composed. For ease of use, while some speedometer with odometer and one-way total odometer, total odometer to record the total vehicle mileage, one-way one-way car used to record the odometer mileage. One way you can always reset the odometer to zero.
Speed ??warning device is to ensure traffic safety and speed table in the speed of sound alarm system installed. If the vehicle speed reaches or exceeds a speed limit (eg 100km / h), then the speed table speed switch to the buzzer circuit connected to sound an alarm.
Second, the oil pressure gauge and oil pressure alarm device
Engine oil pressure gauge when the instructions in the engine lubrication system oil pressure in the main oil the size of the instrument. It includes instruction sheet and the hydraulic oil pressure sensor in two parts.
Oil low pressure alarm system installed in the engine lubrication oil in the main oil pressure is lower than normal, the alarm signal to the driver. Oil low pressure warning device mounted on the dashboard by the low oil warning lights mounted on the engine main oil and the oil pressure sensors trail.
Third, the fuel gauge and fuel low oil alarm equipment
Fuel gauge to indicate the existence of oil vehicle fuel tank. Fuel gauge regulator from the fuel surface with instruction sheet and the oil level sensor.
Fuel low oil alarm is the role of the fuel in the fuel tank is less than a specified value immediately light up alarm to attract the driver's attention.
Fourth, the water table and water temperature warning light
Water table is to indicate the function of the engine cylinder head comprising a coolant water temperature.
Water temperature warning light in the coolant temperature to near the boiling point (eg 95 ~ 98 ℃) when illuminated to attract the driver's attention.
