Marine Instrument Panel with Red Backlit and Steering Indicator Oil Level Water Temperature Oil Pressure Voltage Display Item Type: Marine Instrument PanelMaterial: Aluminum alloy, ABS, stainless steel, tempered glassFunction Display: 85mm speedometer can display: Travel speed 0-200km/H, engine speed 0-8000RPM, light and turn signal reminder; (Comes with GPS speed sensor) 52mm water temperature gauge shows water temperature: 100-250F (40-120℃); (Input signal: 301-22ohms)52mm oil level gauge shows the amount of fuel in the tank: F-1/2-E; (Input signal: 0-190ohms) 52mm oil pressure gauge can display the oil pressure of the tank: 0-10bar ((0-145psi)); (Output signal: 10-184ohms) 52mm voltmeter can display battery voltage: 8-16V; Mode of Operation: Liquid crystal display, stepping motorOperating Voltage: DC12V circuit system; (Except voltmeter, the other four meters can be used in DC24V circuit system) Working Current: ≤100 MA Operating Temperature: -30℃ - + 75℃Storage Temperature: -40℃ - + 85℃ Backlight Color: Red Protection Level: IP67, can work in 1m underwater position, excellent anti fog functionApplication: This instrument panel can be installed in your RV, yacht or engineering car central control position, only need 300x190mm/11.81x7.48in unit area will be 5 meters together, greatly save space and decoration of your central control, and 5 meters are with red backlit and red LED lighting needle, even at night can also clearly view the parameters, At the same time, the multifunctional panel also comes with water temperature alarm, low oil pressure alarm, low voltage alarm, charging indicator, lighting switch, buzzer switch, ENG/Stop switch and other functions, through the panel data to know the state of the engine at any timeApplication:The multifunctional central control panel can be used for engines, generator sets, caravans, yachts, fishing boats, ships, engineering machinery, agricultural machinery, modified vehicles and other fields. Installation Instructions: 1. Make a hole in the pre installation position of the center control about 300x190mm/11.81x7.48in(a little smaller). 2. Put the instrument panel into the open hole, and connect the power supply harness and sensor harness on the back of the instrument panel in turn (please check the instructions for wiring sequence, it is recommended to find a professional electrician to assist in installation). 3. Fasten the panel with screws Stepper Motor Description: Stepper motor is the electrical pulse excitation signal into the corresponding angular displacement or linear displacement of the discrete value control motor, this kind of motor moves one step every time an electric pulse is input, so it is also called pulse motor.
