The appearance of the differential pressure switch is no different from our ordinary switch, but if we simply regard it as a kind of switch device, it is a big mistake. The internal device of the differential pressure switch is much more complex than the ordinary switch. Come down to Hong Kong Aite's differential pressure technician to explain to you the working principle of the differential pressure switch. Although the internal device of the differential pressure switch is very complex, in the final analysis, it is a simple pressure control switch device. When the measured pressure reaches a certain fixed value, it will automatically make the internal device of the differential pressure switch, so that the differential pressure switch Send out alarm signal. Next, I will explain the general working principle of differential pressure switch to you.
Next, the differential pressure technician will introduce several basic types of differential pressure switch to you. The differential pressure switch mainly includes the normally open and normally closed switches, and the functions of these two types of differential pressure switches are not much different in practice.
First, there are two types of differential pressure switches, electronic and mechanical. Electronic differential pressure switches have many functions, but their service life is generally three years. Mechanical differential pressure switches vary in types. Some of them have a very short service life, and they break down in one year. Some of them have a relatively long service life and can be used for 10 years.
Third, the most important device of the differential pressure switch is the sensor of the differential pressure switch, which is related to the level measured by the differential pressure switch, and the material of the sensor made of different manufacturers, so the performance is also very different. Here we introduce that the sensor made of stainless steel is the best and very safe.
Fourth, the differential pressure switch is the alarm only when the pressure exceeds a certain limit value, so our users can also have their own actual needs to work out the most appropriate limit value, so it is very handy to use, so it will make our work more convenient.
Fifthly, because differential pressure switch is connected with wires and circuits, the ways of connecting wires are varied, which can be selected flexibly according to the specific needs of users, so it has great operability;
