Feature: 1. 5 Gauge Set: 85mm speedometer can display driving speed 0‑120km/H, engine speed 0‑8000RPM; 52mm water temp meter shows water temperature 100‑250℉; 52mm fuel level meter shows tank oil volume F‑1/2‑E; 52mm oil pressure meter can show tank oil pressure 0‑10Bar; 52mm voltage meter can show battery voltage 8‑16V. 2. Multifunctional: The instrument panel is equipped with water temperature alarm, low oil pressure alarm, low voltage alarm, charging indication, light switch, buzzer switch, engine stop switch, etc. All 5 gauges are equipped with red backlight and red LED pointer for night use. 3. Rugged Construction: The meter set is made of aluminum alloy panel, 316L stainless steel front cover bezel, antifog curved clear lens, industrial grade electronics and structural components, IP67 waterproof, and can withstand mechanical shock and vibration, ideal for various harsh environments. 4. High Accuracy: All meters use pulse motor to drive the pointer to indicate the corresponding scale, high accuracy and easy to read. Adopt ultra wide working voltage design, long term working voltage is 9‑32V, maximum 36V (≤1 minute), working current ≤100mA, ultra low power consumption. 5. Firm Installation: The back harness connectors of all 5 meters are with snaps, which can ensure a firm connection between the meter and the harness, and still work reliably even when used in strong vibration situations. 6. Widely Used: Easy to install, only 300x190mm unit area, can be used in engines, generator sets, caravans, yachts, fishing boats, ships, construction machinery, agricultural machinery, modified vehicles and other fields. Specification: Item Type: Dash Instrument Panel Material: Aluminum alloy+ABS+stainless steel+tempered glass Function Display: 85mm speedometer can display: driving speed 0-120km/H, engine speed 0-8000RPM, lighting and turn signal light alerts; (speed sensor with 3.9m wire length is included with the speedometer)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 7.48in 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 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..
