FD3051SF Single Flange Pressure Transmitter with Capillary | Flat Diaphragm Type Corrosion-Resistant Explosion-Proof Remote Pressure/Level Measurement Device
The FD3051SLT Single Flange Pressure Transmitter with Capillary is a remote measurement device designed for harsh working conditions, featuring a flat diaphragm (FFW) single flange structure at its core: the flat flange surface (no protrusions) fits closely with the measured medium contact surface, effectively avoiding adhesion and blockage of viscous or crystalline media. Equipped with a stainless steel capillary (length optional 1~10m), it transmits pressure signals via high-temperature resistant silicone oil filling, realizing physical isolation between the sensor and high-temperature, corrosive, or highly viscous media, and structurally solving the industry pain point of sensor damage under extreme conditions.
Features
- FFW flat diaphragm flange: no dead corners, anti-clogging, suitable for viscous/crystalline media
- Capillary + silicone oil remote transmission: isolates high-temp/corrosive media, protects the sensor
- Corrosion-resistant materials (316L/Hastelloy): fits oil & gas/chemical scenarios
- Flameproof certification + IP65 protection: suitable for flammable/explosive high-risk areas
