技术定义与适配语境
典型 过程密封件 会按材料、尺寸公差、适配关系和失效风险在 机械和设备制造 中评估。

A specialized sealing component designed for level sensors that creates a hermetic barrier between the sensor's internal electronics and the measured medium, preventing fluid ingress, leakage, and cross-contamination while maintaining measurement accuracy under varying pressures and temperatures.

组件规格

定义
A specialized sealing component designed for level sensors that creates a hermetic barrier between the sensor's internal electronics and the measured medium, preventing fluid ingress, leakage, and cross-contamination while maintaining measurement accuracy under varying pressures and temperatures.
工作原理
Creates a static or dynamic barrier using elastomeric or metallic materials that compress against mating surfaces, forming a leak-tight seal through controlled deformation and surface adhesion, while allowing sensor signal transmission through the sealed interface.

FKM (Viton)EPDMPTFEsiliconeor stainless steel AISI 316Lhardness 70-90 Shore Atemperature range -40°C to +200°Cpressure rating up to 40 bar.
Seal Type
Static/dynamic O-ring or gasket
Size Range
DN15 to DN100
Leakage Rate
<10^-6 mbar·l/s
Pressure Rating
0-40 bar
Temperature Range
-40°C to +200°C
Media Compatibility
Water, oils, chemicals, food products
标准
ISO 3601-1DIN 3771ASME B16.20FDA 21 CFR 177.2600
