J400-S156B美国UE不锈钢压力开关（J400-S156B US UE stainless steel pressure switch spot ）

J400-S156B American UE stainless steel pressure switch Spot pressure switch working principle: 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 pushed through the connecting guide rod to connect or Disconnect, when the pressure drops or rises to the rated recovery value, 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 produces displacement, directly or through comparison Finally, push the switch element to change the on-off state of the switch element 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. UE pressure switch application and selection considerations 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, refinery units. 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 diaphragm.
