Electric Contact Pressure Gauge
The electric contact pressure gauge is a type of filter press pressure gauge. Compared with ordinary pressure gauges, it has an additional signal transmission function. When the set pressure is reached, it will transmit a signal to the control cabinet to stop or start pressing. It is mainly installed on the hydraulic cylinder to measure the oil cylinder pressure of the filter press. It can not only display the pressure value but also realize automatic control through the set upper and lower limit values. The following is a detailed introduction to the electric contact pressure gauge.
The electric contact pressure gauge is installed on the hydraulic cylinder to measure the pressure of the hydraulic system in real-time. This is essential to ensure the correct tightening and opening of the filter plate. The correct hydraulic pressure can ensure the sealing between the filter plates, avoid leakage, and improve the filtration efficiency.
The electric contact pressure gauge has the function of setting the upper and lower limit pressure. When the hydraulic cylinder pressure reaches the preset upper or lower limit, the electric contact inside the pressure gauge will trigger the electrical control system to automatically start or stop the hydraulic pump. This function can effectively prevent the hydraulic system pressure from being too high or too low and protect the safety of the equipment. For example, when the hydraulic pressure reaches the upper limit, the hydraulic device automatically cuts off the power, and the oil pump stops to avoid damage to the hydraulic cylinder or filter plate caused by excessive pressurization.
The electric contacts in the electric contact pressure gauge may be worn or have poor contact due to long-term use or environmental factors, resulting in the failure of the automatic control function. Regular inspection and maintenance are the key to ensuring its reliability. At the same time, to ensure an accurate reading of the pressure gauge, the electric contact pressure gauge should be calibrated regularly. If the reading is inaccurate, it may cause control errors in the hydraulic system and affect the normal operation of the equipment.
Therefore, it is necessary to select an electric contact pressure gauge with a suitable pressure range, high accuracy, and good durability to meet the requirements of the hydraulic system. When installing, ensure that the electric contact pressure gauge is installed in a suitable position near the hydraulic cylinder to facilitate the operator reading and adjusting it while avoiding the influence of vibration and shock.
