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. The main parameters of the US UE pressure switch Set point repeatability Temperature switch: ±1% within the adjustable range 190-194.183-189.483-489.565-567.610-680.490-494 and other models are ±1.5% of the adjustable range; There is an internal set point locking device . Shock resistance is tested by 15G, 10 millisecond cycle. The set point can be reproduced. Vibration resistance is tested by 2.5G, 5 ~ 500HZ vibration, and the set point can be reproduced.Housing die-cast aluminum alloy (copper max. 0.6%). Epoxy coated.
