Air micro differential pressure switch, also called wind pressure switch or differential pressure switch, can measure the differential pressure, negative pressure or gauge pressure (static pressure), and convert the pressure signal into the on / off of the switch to control the circuit. The product can also intuitively rotate the knob to the required pressure according to the field needs, and can ensure the accuracy of the pressure.
Measuring medium: This product can detect the weak change of air, non combustible or non corrosive gas
Product certification: CE
The pressure connection mode of air micro differential pressure switch produced by Hong Kong Aite Co., Ltd. is two φ 6-shaped joints, φ 7 hose connection and hose connection (see above). Mark "+" and "-" respectively at positive pressure end (high pressure) and low pressure end (vacuum). In order to obtain the fastest response time, it is recommended that the length of hose with inner diameter of φ 5 should not exceed 15m.

Loosen the upper cover screws and open the upper cover. The terminal block can be seen. The cable enters the shell through the waterproof locking device and is fixed on the terminal board. The SPDT electrical connection mode of the air micro differential pressure switch is shown in the figure above: 3 is the common terminal, 2 is the normally open contact, and 1 is the normally closed contact
