digital water level gauge
Our company Nanjing Hemu International Trade Co. LTD produces and sells water level gauge, oil level gauge, speedometer, tachometer, etc., include the digital and needle types, as well as the latest professional product parameters, real-time quotation, market situation, high-quality commodity wholesale, supplier and other information related to marine water level gauge.
It is suitable for various water level sensors to display the position of water tank liquid level; The instrument adopts cross coil to drive the pointer, which has good durability and earthquake resistance and anti fog function. Main application fields: boats, engineering machinery, vehicles, generator sets, engines, agricultural machinery, etc.
We professionally customize the digital water level gauge with good durability, safe material and shockproof housing.We have many big repeat customers. Scope of application: ships, yachts, RV, modified vehicles, off-road vehicles, mobile toilets, trucks, trucks, motorcycles, excavators, logging machines, road rollers, bulldozers, ATVs, fire engines, police cars, emergency vehicles, trains, mechanical equipment, etc.The harness connector is provided with a clip, which can ensure the firm connection between the instrument and the harness,that is, it still works reliably when used in places with strong vibration.
The existing RV water temperature gauge, water level gauge and voltmeter are generally set separately, and there is no alarm prompt of high voltage or low voltage. They can only display the water level of a group of liquid tanks. The circuit routing is complex. Most of the water level display accuracy is 40mm, and the display accuracy is not high enough.
In order to solve the above problems, the utility model provides an RV water temperature and water level gauge with simple structure, integrated display voltage, water temperature and water position, alarm prompt and capable of displaying the conditions of two groups of liquid tanks.
The RV water temperature and water level gauge comprises a main shell and a circuit board, the circuit board is fixed in the main shell through screws, the circuit board is externally connected with the RV battery, the back of the circuit board is provided with MCU control chip, buzzer and relay, the front of the circuit board is provided with a display screen, and the display screen includes voltage display screen, water volume display screen and water temperature display screen, The front of the circuit board is also provided with function keys and indicator lights, the display screen, buzzer, relay and indicator lights are connected with the output end of MCU control chip, the function keys are connected with the input end of MCU control chip, the display screen, function keys and indicator lights are clamped on the surface of the main shell, and also includes a sensor probe, in which a water level sensor The input end of the MCU control chip is provided with a double interface, and the sensor probe is connected with the interface through a four core shielded extension wire.
Specifically, the water level display screen, voltage display screen, indicator light and function keys are arranged on the left side of the main shell from top to bottom, and the water volume display screen is arranged on the right side of the main shell in a vertical strip shape.
