Pressure switch related terms
Pressure: The electronic pressure switch maintains its maximum pressure for its normal performance. However, when the electronic pressure switch is used for overpressure, the sensitive element will produce a continuous deformation, then the pressure setting will change, the electronic pressure switch will not be able to play its normal performance or even damage. Accuracy: Indicates the accuracy of the equipment, including linearity, tolerance, hysteresis, repeatability, and so on. Nagano's current pressure switch up to the highest accuracy of ± 0.5% F.S, model CB33. Maximum pressure (Max.P): Maximum pressure range. Full scale (F.S): The difference between the maximum and minimum pressure ranges. The difference between the action value and the reset value is set, for example, when the value is 1MPa and the actual reset value is 0.9MPa, the difference is 0.1MPa. Temperature: refers to the internal mechanism of the instrument, sensitive components such as work will not occur when the temperature range of continuous deformation. General pressure switch recommended operating temperature range of -5 ~ 400C, if the medium temperature is too high, consider adding an attached siphon (irrigation), to achieve the purpose of cooling.
Pressure switch sub-explosion-proof pressure switch, mechanical pressure switch, the United States UE pressure switch for pure mechanical deformation caused by micro-switch action. When the pressure increases, the role of different sensing pressure components (diaphragm, bellows, piston) deformation, will move up, through the railing spring and other mechanical structure, and ultimately start the top of the micro-switch, the electrical signal output. UE pressure switch set from the functional principle is divided into continuous displacement and force balance type.
