- Function Features: Sealed diaphragm structure, high‑precision pressure detection, excellent temperature stability, standard 4‑20mA signal output compatible with all industrial control systemsYokogawa Electric Corporation.
- Material Composition: 316L stainless steel housing, Hastelloy C pressure‑sensing diaphragm, copper alloy electrical terminals, high‑temperature‑resistant insulating materials.
- Structural Features: Compact cylindrical miniature structure, integrated process pressure interface and electrical wiring interface, anti‑vibration sealed design.
- Working Principle: Pressure changes deform the internal capacitive diaphragm, converting mechanical pressure changes into capacitance changes; the built‑in circuit converts capacitance signals into standard 4‑20mA electrical signals.
- Advantage Highlights: Ultra‑high measurement precision, strong corrosion resistance, compact lightweight design, wide high‑pressure measurement range, long‑term zero‑point stability.
- Applicable Industries: Hydraulic engineering, oil and gas exploration, high‑pressure chemical reaction vessels, mechanical pressure testing, process pipeline pressure monitoring.
- Model Series: FP201 Series Miniature High‑Precision Pressure Sensors
- Installation Requirements: Install vertically or horizontally on process pipelines/vessels; use standard thread connection; ensure pressure‑sensing diaphragm is fully exposed to measured medium; maintain vibration‑free installation position.
- Usage Notes: Avoid pressure impact exceeding measurement range; clean pressure‑sensing diaphragm regularly for viscous‑medium applications; prohibit use in strong‑corrosion media incompatible with Hastelloy C.
