A hydraulic pressure gauge is a device used to measure the pressure of a hydraulic system. It consists of a dial or digital display that shows the pressure reading in units of force per unit area, such as pounds per square inch (psi) or bar.
The gauge is typically connected to the hydraulic system through a pressure port or a pressure transducer. When the hydraulic fluid flows through the system, it exerts a force on the gauge, which is then converted into a pressure reading on the display.
Hydraulic pressure gauges are commonly used in various industries and applications, such as automotive, manufacturing, construction, and aerospace. They are essential for monitoring the pressure levels in hydraulic systems to ensure proper functioning and prevent damage or failure.
Some hydraulic pressure gauges are designed for specific pressure ranges, while others are adjustable or have a wide range of measurement capabilities. They may also have additional features like maximum pressure indicators, peak hold functions, or digital interfaces for data logging.
Overall, hydraulic pressure gauges play a crucial role in maintaining the performance and safety of hydraulic systems by providing accurate pressure readings for troubleshooting, maintenance, and operational purposes.

Gray mold has always been a major concern in the prevention and control of fruit and vegetable diseases. This fungal disease is most prevalent during the flowering and fruiting stages, making it a critical issue for growers. So, how can you effectively manage gray mold after winter? What are the most noticeable signs of its occurrence? Let’s explore with the **Pesticide Network**.
In general, gray mold thrives in low temperatures, high humidity, and poor light conditions. During winter, it's crucial to manage these factors as much as possible. Maintaining proper temperature and humidity levels, along with ensuring adequate sunlight, can significantly reduce the risk of gray mold development.
Gray mold typically affects flowers, fruits, leaves, and stems. To prevent and control it effectively, here are some key strategies:
First, managing humidity is essential. High moisture levels create an ideal environment for the fungus to grow. Controlling humidity through ventilation and dehumidification can greatly lower the incidence of gray mold.
Second, flowers and young fruits are the most vulnerable to infection. The period of flowering and fruit set is when gray mold outbreaks are most common. Therefore, it's vital to apply preventive measures during this time. Spraying appropriate fungicides, such as 400g/L suspension of chlorothalonil at 1500 times dilution, 65% mancozeb WP diluted 600 times, 65% carbendazim WP diluted 1000–1500 times, or 50% chlorpyrifos water-dispersible granules at 3000 times, can help protect crops. In addition, artificial pollination can also be used to improve fruit set and reduce the chance of infection.
Third, implementing comprehensive control methods is crucial. Regularly removing infected leaves, flowers, and fruits is important. When removing diseased parts, handle them carefully and place them in sealed plastic bags to prevent the spread of spores. Dispose of them properly, away from the fields, and do not leave them on the ground. For petals that are prone to infection, using bumblebee pollination can help them fall off naturally, reducing the chances of infection.
When plant density is high, consider using smoke agents like pyraclostrobin or chlorothalonil for fumigation. Always follow safety guidelines and environmental protection standards when applying pesticides. Make sure to observe the recommended waiting periods before harvesting to ensure food safety.
