FD3051LD Remote Flange Liquid Level Transmitter with High-Temperature & Corrosion Isolation, Prevents Medium Crystallization and Clogging, and Smart Multi-Protocol Communication

In industries such as petrochemicals, chemicals, power generation, and pharmaceuticals, measuring the level, interface, and differential pressure of high-temperature, highly corrosive, easy-to-crystallize, or viscous media remains a process control challenge. Traditional single-flange or direct measurement methods are prone to distortion caused by clogging, corrosion, or high temperatures. The FRD Sensor FD3051LD Dual Flange Differential Pressure Transmitter is engineered for these severe conditions. By connecting high-precision single-crystal silicon sensing elements to remote seal diaphragms via capillary tubes, it effectively isolates high temperatures, corrosion, and viscous media, ensuring measurement precision and long-term stability in process control.

• Effective High-Temperature & Corrosion Isolation: Remote flange structures physically isolate the instrument from the process medium, easily handling high temperatures, acids, alkalis, and corrosive conditions.
• Prevents Medium Crystallization and Clogging: Flush or extended flange designs combined with capillary fill fluid eliminate blockages caused by crystallizing or solidifying media.
• Superior Long-Term Stability: Combines advanced single-crystal silicon sensing technology with intelligent digital compensation to minimize drift caused by temperature fluctuations.
• Smart Multi-Protocol Communication: Supports 4–20 mA, HART, and RS485 protocols for seamless PLC/DCS integration and modern smart factory remote monitoring.

FRD Sensor offers comprehensive OEM & ODM customization services for the FD3051LD Dual Flange Differential Pressure Transmitter. We support custom flange standards (ANSI, DIN, JIS), flange sizes, capillary lengths, fill fluid types (high-temp/food-grade silicone oil), and special wetted materials (Hastelloy, Monel, Tantalum), alongside personalized appearance, brand logos, and mass production support.

1. Capillary & Flange Inspection: Check capillaries for bends or crushing, and inspect flange diaphragms for damage, adhesion, or sediment buildup.
2. Electrical & Power Check: Verify loop voltage, range settings, and HART/RS485 communication status.
3. Zero & Ambient Temperature Verification: Calibrate the zero point under unpressurized conditions and check for thermal expansion/contraction effects of fill fluid.
4. Sensing Core & Electronic Module Evaluation: If external structures are normal, further check the single-crystal silicon element performance and electronic module stability.

The FRD Sensor FD3051LD Dual Flange Differential Pressure Transmitter is specifically engineered for severe industrial environments involving high temperatures, strong corrosion, easy crystallization, and high viscosity. By utilizing advanced single-crystal silicon sensing technology combined with remote seal diaphragms and capillary isolation, it reliably prevents clogging and measurement distortion. Supported by flexible OEM/ODM customization and smart multi-protocol communication, it delivers precise, long-term stable level and differential pressure measurement for modern process automation.
