9. Length Range: 100mm - 1500mm, lengths can be customized to customer requirements; equipped with a gauge at the top, featuring a pointer to indicate liquid level.
10. Signal Output: Optional, capable of outputting 9 resistive signals, resistance range customizable according to customer requirements.
11. Alarm Switch: Optional, available in high or low alarm settings. Alarm current less than 500mA. Alarm points can be set at 9/10 and 1/10 positions.
Mechanical oil gauges are categorized into vibration-resistant and vibration-proof oil pressure gauges. The vibration-resistant type features a spiral spring tube and housing filled with high-viscosity mineral silicone oil, which serves as a damping agent. This reduces pointer vibration and enhances vibration resistance. The mechanical oil gauge integrates liquid level detection and display in one unit, eliminating the need for any external devices. It can directly display liquid level output signals. Optional configurations can output 9 resistance signals, with resistance ranges customizable to meet customer requirements. High and low level alarm functions can also be added as per customer need.
The mechanical fuel gauge is a traditional type that uses an oil float inside the fuel tank and a pull cord to sense the oil level, which is then relayed to the dashboard for display through a needle. It operates without power and can be equipped with high and low level alarm functions as per customer requirements. The mechanical fuel gauge is a simple tool for checking hydraulic system pressure, featuring a hollow spring tube bent into an arc, a pull rod, a rack, gears, a needle, and a damping mechanism. When checking the oil pressure with the mechanical fuel gauge, it should be kept in a vertical position with the line of sight perpendicular to the gauge face to accurately read the pressure value.
Installation requirements for mechanical oil gauges:
Choose areas with minimal dust, no corrosive gases nearby, no severe vibration, and a considerable distance from heat sources as much as possible.
2. Flow meter installation environment temperature is -15 to 40°C.
