- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are used in this force sensor's construction?
**A**: Our force sensors feature durable stainless steel and aluminum alloy components, with Constantan foil strain gauges and epoxy resin for protection and stability in industrial environments.

### Q: How does this force sensor convert mechanical force to electrical signals?
**A**: The sensor uses strain gauges bonded to an elastic element that deforms under force. This deformation changes electrical resistance in a Wheatstone bridge circuit, producing a proportional voltage output signal.

### Q: What are the key components in this force sensor's BOM?
**A**: The bill of materials includes: elastic spring element, precision strain gauges, Wheatstone bridge circuit for signal conditioning, and a protective housing/enclosure for industrial durability.
