UE壓力開關的特點有哪些（美國UE壓力開關的特點 ）

Features of the US UE pressure switch Performance characteristics: * One switch model output * Epoxy-coated and cast-aluminum housing meets NEMA 4X standards * Set point lock to prevent misuse * Heat trace level antifreeze protection * Pressure resistance up to 10.000psi (689.5bar) * Adjustable range pressure: 30″Hg Vac to 5000psi (-1 to 344.7bar) US UE Switch 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. It is also applicable to the high and low pressure protection control of various equipment 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.
