UE压力开关防爆J120-15834死区可调微动开关（U.S. UE pressure switch explosion-proof J120-15834 dead zone adjustable micro switch ）

Precautions for installation of pressure switch Pressure switches are widely used in high and low pressure protection control of household, commercial and automotive refrigeration systems, steam working conditions and power stations; accumulators, receivers, flash tanks, separators, scrubbers, oil refineries device. It is also applicable to the high and low pressure protection control of various equipment tools. However, in the selection of pressure switches, the following points must be paid attention to: 1. The necessity of explosion-proof: explosion-proof forms are divided into flameproof type and intrinsically safe type. 2. Do you need to bring instructions: according to customer instructions. 3. Number of contacts: one contact (one output) or two contacts (two outputs). 4. Determination of setting value and pressure range: the recommended setting range is between 30% and 65% of the pressure range, and the settable range is between 15% and 90% of the pressure range. 5. The form of connection difference: adjustable or fixed. 6. Whether there is pulsation: If the pressure pulsates or vibrates, a throttle valve is required to suppress the damage to the instrument caused by the pulsating pressure. 7. Occasions with a diaphragm: When measuring corrosiveness, high viscosity or high temperature, it is necessary to use a UE pressure switch with a diaphragm . T6, imported flameproof pressure switches must pass UL, CSA, CE and other international certifications. It can be used in explosive areas and strong corrosive atmosphere environments. Flameproof pressure switches are available in different pressure, differential pressure, vacuum and temperature ranges. Common applications include electric power, petroleum, chemical industry, metallurgy, boiler, food machinery, environmental protection equipment and other industries. Mechanical type Mechanical pressure switch, the action of the micro switch is caused by purely mechanical deformation. When the pressure increases, the different sensing pressure components (diaphragm, bellows, piston) will be deformed and will move upwards. Through the mechanical structure such as the railing spring, the uppermost micro switch will be activated to output the electrical signal.Type selection of J120 series micro switch with adjustable dead zone
