Tips: Precautions of Using Pressure Switch.

Pressure switches are widely used in the high and low pressure protection control of household, commercial, and automobile refrigeration systems, steam conditions and power stations; accumulators, receivers, flash tanks, separators, scrubbers, oil refining devices. It can also be applied to the high and low pressure protection control of various equipment and tools. But in the selection of pressure switch, the following points must be paid attention to:
1. The necessity of explosion-proof: explosion-proof forms are divided into explosion-proof type and intrinsically safe type, and most of Nagano products are explosion-proof type.
2. Whether 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 setting range is between 15% and 90% of the pressure range.
5. The form of differential connection: adjustable or fixed.
6. Whether there is pulsation: If the pressure is pulsating or vibrating, a throttle valve is required to suppress the damage of the pulsating pressure to the instrument.
7. The occasion with diaphragm: when measuring corrosiveness, high viscosity or high temperature, it is necessary to select a diaphragm.
