Product overview
Stepped load-pin body
A wider cylindrical rear section leads to a stepped pin with circular side faces and visible openings near the end. The lower fitting carries a spring sleeve and short cable.
Double-shear construction for load measurement through a pin.
Selected bridge configuration
- Rated load
- 3 t
- Sensitivity
- 1.0 ±0.05 mV/V
- Bridge excitation
- 5–12 V
Bridge creep reference: ±0.05% FS.
Configuration and selection
- Signal configuration
- The selected bridge configuration has 1.0 ±0.05 mV/V sensitivity. Built-in transmitter configurations can convert the measurement to current or voltage signals; the bridge excitation and resistance figures describe the bridge reference.
- Material
- Alloy-steel or stainless-steel options.
Pin geometry and radial loading
Double-shear load-pin construction
The pin measures radial force at a pulley shaft and is used in hoisting, water-conservancy and marine monitoring equipment. The drawing identifies the head, sensing-shaft sections, shaft slot and end bore.
