Unlike traditional capacitive sensors that rely on physical displacement of a diaphragm to measure capacitance, the DPharp sensor uses two micro-resonators to measure the pressure as a frequency. This leads to superior accuracy, high stability, and immunity to changes in ambient temperature or static pressure.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can this transmitter be used for corrosive process fluids?\u003c\/p\u003e\n\u003cp\u003eA: Yes. The \"HC\" option indicates the use of Hastelloy C diaphragms, which are highly resistant to chemical corrosion compared to standard 316 stainless steel.\u003c\/p\u003e\n\u003cp\u003eQ: Is this model suitable for hazardous environments?\u003c\/p\u003e\n\u003cp\u003eA: Yes. The suffix codes FF1 and associated certifications indicate that this unit is designed and approved for use in explosive atmospheres (e.g., FM\/ATEX\/IECEx).
