Product Description
FD3051SLD Double Flange Remote Pressure Level Transmitter | Corrosion-Resistant Explosion-Proof Level Measurement Device for Closed Containers
The FD3051LD Double Flange Remote Pressure Level Transmitter is a core measurement device customized for harsh working conditions of closed containers. Adopting a double flange + capillary remote transmission structure, it transmits pressure signals through filled silicone oil, avoiding direct contact between the sensor and high-temperature, corrosive, viscous, or crystalline media, and structurally solving the industry pain points of medium adhesion, blockage, and sensor corrosion. The product is compatible with various flange types including Flat Type (FFW) and Insertion Cylinder Type (EFW), with flange sizes covering DN50~DN100 and rated pressure up to PN10MPa/Class 600. Diaphragms are available in corrosion-resistant materials such as 316L stainless steel, Hastelloy C, Tantalum, and Monel; some materials support FEP/PFA coating or PTFE film, resisting erosion from complex media like strong acids, strong alkalis, and sulfides.
Features
- Exclusive remote flange structure: Adapts to industrial sealed vessel scenarios, avoiding direct contact between the transmitter body and the measured liquid to improve device adaptability
- Liquid-medium-specific design: Optimized measurement logic only for liquid media, ensuring the accuracy of liquid level data in sealed vessels
- Multiple corrosion-resistant diaphragms: Optional materials (316L, Hastelloy, Tantalum, etc.) for various highly corrosive liquid media
- Wide level range coverage: 0~0.6m to 10m, meeting level measurement needs of sealed vessels with different volumes
- Easy on-site installation: Remote flange structure simplifies deployment, adapting to installation conditions of various industrial sealed vessels
- Wide temperature condition compatibility: Broad temperature resistance range enables stable operation in high/low-temperature sealed working environments
- Dual signal output adaptation: Supports 4mA~20mA+HART and RS485, compatible with analog and digital industrial control systems
