Intelligent pressure switch

Intelligent pressure switch

The working principle of a pressure switch is that when the pressure inside the system is higher or lower than the rated safety pressure, the disc inside the sensor instantly moves, and the switch joint is connected or disconnected by the connecting guide rod. When the pressure drops to or rises to the rated recovery value, the disc instantly resets, and the switch automatically resets. In other words, when the measured pressure exceeds the rated value, the free end of the elastic element displacement, directly or after comparison, pushes the switch element 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.

Intelligent pressure switch
The main categories of pressure switches include normally open and normally closed. The main features are:
1. Adopting the British style pipe thread quick connector or copper pipe welding installation structure, the installation is flexible, easy to use, and does not require special installation and fixation.
2. The plug-in wire type connection can be freely selected by users.
3. Sealed stainless steel sensor is safe and reliable.
4. Manufacturing can be carried out within the pressure range according to the pressure value selected by the user.
A pressure switch is a device that is combined with an electrical switch. When the pre-set fluid pressure is reached, the switch contact will activate. 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.
2. Main sensitive components of pressure switch 2.1 Bellows
Features: It has better durability and vibration resistance than Bourdon tubes, with a large adjustable range of connection and disconnection differences. The main materials are stainless steel, phosphor bronze, etc. The price is relatively high, but the measurable pressure range is small, up to 40MPa (CB33) 2.2 diaphragm
