美国UE双点输出压力开关J402-S164B（US UE dual output pressure switch J402-S164B ）

US UE dual-point output pressure switch J402-S164B J402-S156B       working principle The working principle of the pressure switch: When the pressure in the system is higher or lower than the rated safety pressure, the disc in the sensor moves instantaneously, and the switch joint is connected or disconnected by connecting the guide rod. When the pressure drops or rises When the rated recovery value is reached, the disc resets instantaneously and the switch automatically resets, or in simple terms, when the measured pressure exceeds the rated value, the free end of the elastic element is displaced, and the switch element is pushed directly or after comparison to change the switch element. On-off state to achieve the purpose of controlling the measured pressure. The elastic components used in the pressure switch include single coil spring tube, diaphragm, bellows and so on. Precautions Pressure switches are widely used in high and low pressure protection and control of household, commercial and automotive refrigeration systems, steam working conditions and power stations; accumulators, receivers, flash tanks, separators, scrubbers, refinery units. Also applicable to various High and low pressure protection control for spare tools. However, in the selection of the pressure switch, 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 diaphragm. Product features:  ● Two-point and three-point settings provide multi-point output ● One, two or three switch outputs, which can be set separately within 100% of the set point ● Epoxy resin shell design meets NEMA 4X requirements ● A variety of diaphragms are available, such as 316SS, brass, Nitrile and Teflon ● Choose a reference scale or turn the screw to adjust the set point ● Common models of UE J400 series mechanical pressure switches:J400-S126B/S134B/S137B/S144B/S152B/S156B/S164B J400-126/134/137/144/152/156/164 J402-S126B/S134B/S137B/S144B/S152B/S156B/S16412 J4023-1641 /137/144/152/156/164 American UE mechanical dual-point output pressure switch J402-S164B pressure parameters:
