does the bellows sensing element differ from a standard piston or diaphragm design?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe metal bellows sensing element combines the high accuracy and low-pressure sensitivity of a diaphragm with the long stroke and durability of a piston. It deforms linearly in response to fluid pressure changes without relying on dynamic rubber seals, making it highly resistant to chemical aging and temperature-induced calibration drift.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat specific field actions are enabled by the SPDT electrical contact system?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe single-pole double-throw (SPDT) contact assembly features one common terminal, one normally closed (NC) contact, and one normally open (NO) contact. This configuration enables dual-function control logic. For example, it can simultaneously open a circuit to cut power to a high-pressure pump while closing a parallel circuit to trigger a remote HMI alarm indicator.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy does a compact electromechanical switch carry a 1.5 kg shipping specification?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 1.5 kg rating accounts for heavy-wall industrial packaging. Because the internal snap-action microswitch and pre-tensioned calibration springs can lose accuracy if subjected to severe impact, the unit is packed in thick anti-vibration materials, sealed against moisture, and boxed in rigid cardboard to ensure safe delivery through global supply channels.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eMechanical Installation and Electrical Wiring Guidelines\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eBellows Orientation and Mechanical Support:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eMount the pressure switch directly onto a rigid bulkhead or structural bracket to protect it from line vibrations.
