Fire pressure switch

The main categories of fire 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.

The fire pressure switch is a device combined with the electrical switch. When the pre-set fluid pressure is reached, the switch contact will act. 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 fire pressure switch 2.1 Bellows

Features: It has better durability and vibration resistance than Bourdon tubes, with a large adjustable range of connection difference. The main materials are stainless steel, phosphor bronze, etc. The price is relatively high, but the measurable pressure range is small, with a maximum of 40MPa (CB33) and 2.2 diaphragm

Features: It has excellent corrosion resistance and is mainly made of materials such as NBR and fluororubber. Sensitive components such as CS and CL series are also used. The selection of quick and easy automation for fire pressure switches is included. [1]
