Spot supply HYDAC spring pressure switch

Spot supply HYDAC spring pressure switchIt is a device combined with an electrical switch that activates the switch contacts when the pre-set fluid pressure is reached. It is mainly used for outputting alarm or control signals on industrial equipment such as power plants, petrochemicals, and metallurgy industries. It has important applications in the industrial field and can prevent damage to important devices in production engineering, avoiding major production accidents.

Pressure sensors are mainly used in fields such as booster cylinders, boosters, gas-liquid booster cylinders, gas-liquid boosters, presses, compressors, air conditioning and refrigeration equipment.

1. Applied to hydraulic systems

HYDAC pressure sensors are mainly used in hydraulic systems to achieve closed-loop control of force. When the control valve core suddenly moves, a peak pressure several times the system working pressure will be formed in a very short period of time. In typical walking machinery and industrial hydraulics, if such working conditions are not taken into account during design, any pressure sensor will quickly be damaged. It is necessary to use impact resistant pressure sensors. There are two main methods to achieve impact resistance for pressure sensors: one is to replace the strain gauge chip, and the other is to connect an external coil. Generally, one method is used in hydraulic systems, mainly because it is easy to install. Another reason is that the pressure sensor also has to withstand continuous pressure pulsation from the hydraulic pump.

2. Applied to security control systems
HYDAC pressure sensorIt is often used in safety control systems, mainly targeting the safety management system of the air compressor itself. There are many sensor applications in the field of safety control, and it is not surprising that pressure sensors, as a very common type of sensor, are used in safety control systems.

In the field of safety control, applications are generally considered from the perspective of performance, price, and practical safety and convenience. It has been proven that choosing pressure sensors has a very good effect. Pressure sensors use mechanical equipment processing technology to install some components and signal conditioning devices on a small chip. So small size is also one of its advantages, in addition to that, cheap price is another major advantage. To some extent, it can improve the accuracy of system testing. In the safety control system, installing pressure sensors in the pipeline equipment at the outlet to control the pressure brought by the compressor to a certain extent is a certain protective measure and a very effective control system. After the compressor starts normally, if the pressure value does not reach the upper limit, the controller will open the air inlet and adjust it to achieve the maximum power of the equipment.

Spot supply HYDAC spring pressure switchThe working principle of the sensor is that when the pressure inside the system is higher or lower than the rated safety pressure, the disc inside the sensor instantly moves. The switch joint is connected or disconnected by the connecting guide rod. When the pressure drops or rises to the rated recovery value, the disc instantly resets and the switch automatically resets. Simply put, when the measured pressure exceeds the rated value, the free end of the elastic element is displaced, and the switch element is directly or after comparison pushed to change the on/off state of the switch element, achieving the purpose of controlling the measured pressure. The elastic components used in pressure switches include single coil spring tubes, diaphragms, bellows, and corrugated tubes.
