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
