Component Specifications

Definition
A specialized sealing and enclosure system designed specifically for force sensors and load cells to provide environmental protection against dust, moisture, chemicals, and mechanical impacts. This component ensures the sensor's internal electronics and strain gauges remain isolated from external factors that could compromise measurement precision, signal integrity, or operational lifespan in industrial applications.
Working Principle
Creates a hermetic or high-integrity barrier around the force sensor using compression seals, gaskets, or welded joints that prevent ingress of contaminants while allowing force transmission through designed load paths. The enclosure maintains structural rigidity to prevent deflection that could affect calibration, with internal damping materials sometimes used to absorb vibration and shock loads.
Materials
Stainless steel (304/316), aluminum alloys (6061-T6), engineered plastics (PEEK, PTFE), nitrile rubber gaskets, silicone seals, epoxy potting compounds, anodized or powder-coated finishes for corrosion resistance.
Technical Parameters
  • Weight Varies by size (50g-5kg)
  • Mounting Threaded, flange, or custom bracket
  • IP Rating IP67/IP68/IP69K
  • Seal Type O-ring, lip seal, or welded
  • Pressure Rating Up to 10 bar
  • EMI/RFI Shielding Optional conductive coatings
  • Temperature Range -40°C to +85°C
Standards
ISO 376, DIN 51221, ISO 60529, DIN 40050-9

Frequently Asked Questions

What IP rating is recommended for food manufacturing environments?

IP69K is recommended for food manufacturing as it provides protection against high-pressure, high-temperature washdowns with cleaning chemicals while preventing bacterial ingress.

How does the enclosure affect measurement accuracy?

Properly designed enclosures maintain accuracy through rigid construction that prevents deflection, while internal damping materials can actually improve accuracy by absorbing vibration. The key is ensuring force transmission paths remain uncompromised.

Can sealed enclosures be used in explosive atmospheres?

Yes, with ATEX or IECEx certification and proper flame-path design. Explosion-proof enclosures use specially engineered joints and seals that prevent ignition transmission.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
