Key Differences |
Application Scenarios |
Strengths & Weaknesses |
|
139554-01 |
Internal terminal AC LVDT-exclusive module, optimized for high-precision closed-loop control |
Valve/shaft displacement precision monitoring |
IP67 protection ±0.01% accuracy but Higher cost |
|
139567-01 |
Identical function with external terminal block (requires additional 141216-01) |
Field wiring scenarios requiring frequent maintenance |
Enhanced expandability but Reduced IP54 protection rating |
|
135137-01 |
Supports proximity probes/DC LVDT, incompatible with AC LVDT |
General position monitoring |
20% lower cost but Lower precision/frequency response vs. 139554-01 |
