Boat Instrument Panel Tachometer Fuel Level Water Temperature Oil Pressure Meter Voltmeter 5 Dash Gauge Set Item Type: Dash Instrument Panel Material: Aluminum alloy+ABS+stainless steel+tempered glass Function Display: 85mm tachometer can display: engine speed 0-4000RPM, 99999.9H timing 52mm water temperature gauge shows water temperature: 100-250℉ (40-120 ℃); (Input signal: 301-22ohms) The 52mm oil level gauge shows the oil volume of the oil tank: F-1/2-E; (Input signal: 0-190ohms) The 52mm oil pressure gauge can display the oil pressure of the oil tank: 0-10Bar (0-145psi); (Input signal: 10-184ohms) 52mm voltmeter can display battery voltage: 8-16V; Operation Mode: LCD display, stepper motor Working Voltage: DC12V circuit system; (Except for the voltmeter, the other four instruments can work in the DC24V circuit system) Working Current: ≤ 100 MA Working Temperature: - 30 ℃ -+75 ℃ Storage Temperature: - 40 ℃ -+85 ℃ Backlight Color: Red Protection Grade: IP67, can work at 1m underwater, excellent antifog function; Application: This instrument panel can be installed in the central control position of your RV yacht or engineering vehicle. It only needs 300 x 190mm / 11.8 x 7.5in unit area to combine the five instruments together, which greatly saves space and decorate your central control. The five instruments are equipped with red back light and red LED light needles, which can clearly view all parameters even at night. At the same time, the multifunction panel also includes water temperature alarm, low oil pressure alarm and low voltage alarm, The charging indicator, lighting switch, BUZZER switch, ENG STOP switch and other functions can be used to know the status of the engine at any time through the data on the panel Application: The central control multifunction refitting panel can be used in the fields of engine, generator set, RV, yacht, fishing boat, ship, engineering machinery, agricultural machinery, refitting vehicle, etc. Stepping Motor Description: Stepping motor is a discrete value control motor that converts the electric pulse excitation signal into the corresponding angular displacement or linear displacement. This type of motor moves one step every time an electric pulse is input, so it is also called pulse motor.
