Process Seal Component – Machinery and Equipment Manufacturing

Q: What is the primary function of a process seal in level sensors?

To prevent fluid leakage and protect sensor electronics from media exposure while maintaining measurement integrity.

Q: How do I select the right material for a process seal?

Based on chemical compatibility, temperature range, pressure requirements, and industry regulations like FDA for food contact.

Q: What are common failure modes of process seals?

Compression set, chemical degradation, extrusion under pressure, and installation damage.

Component Specifications

Definition

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.

Working Principle

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.

Materials

FKM (Viton), EPDM, PTFE, silicone, or stainless steel AISI 316L; hardness 70-90 Shore A; temperature range -40°C to +200°C; pressure rating up to 40 bar.

Technical Parameters

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

Standards

ISO 3601-1, DIN 3771, ASME B16.20, FDA 21 CFR 177.2600
