Strain Gauge Displacement Transducer AML/SGD

Product catalog summary

Overview
The AML/SGD series displacement transducers are designed to provide a linearly proportional voltage output based on the movement of a guided spindle. They utilize a 4-arm active Wheatstone bridge with a nominal impedance of 350 ohms, ensuring excellent non-linearity, low current consumption, and good temperature stability. These transducers are suitable for various applications, including research and development, industrial, aerospace, civil engineering, and automotive sectors.

- Input Resistance: 350 ohms (450 ohms on 100mm)
- Output Resistance: 350 ohms (270 ohms on 100mm)
- Insulation Resistance: Greater than 2000 Megaohms

Mechanical Characteristics
- Spring Force: 50-250 gf (progressive)
- Cable: 2 Metre 4 Core Screened, bend radius 10mm
- Weight (excluding cable): Varies by model, from 125 grams to 600 grams

Operational Notes
1. Ensure the outer case is not distorted when clamping the sensor; a full diameter clamp is recommended.
2. Additional protection is advised for use in hostile environments.
3. Special tools are required to remove the plunger tip (anvil) to prevent spindle damage.
4. The plunger tip (anvil) acts as a positive overload protection stop. If removed, the threaded end of the plunger must not enter the case.

Dimensions
Dimensions vary based on stroke range, with specific measurements provided for each model. The 100mm version includes a spring located on the outside of the plunger.
