Park Nuclear provides a Direct Replacement for Engdahl PAR Recorder and Plate Series
The Engdahl PAR (Peak Acceleration Recorder) series — models 400, 1200, and 1600 — are legacy seismic monitoring instruments. These systems are designed to record peak ground accelerations during seismic events, typically used for structural response analysis and safety assessment.
Model Breakdown
PAR 400 Series
- Type: Basic seismic recorder with peak acceleration recording.
- Use: Primarily for simple, single-axis or limited multi-axis installations.
PAR 1200 Series
- Type: Mid-range system with more advanced capability.
- Use: Suitable for more complex monitoring environments, including multiple channels or zones.
PAR 1600 Series
- Type: Advanced peak acceleration recorder with comprehensive monitoring capability.
- Use: Designed for critical infrastructure with high seismic reliability demands.
Mounting Plate Sets
Each PAR unit was installed using a dedicated mounting plate set.
Mounting plates were model-specific, and designed to maintain proper seismic coupling, often with shock-absorbing or vibration-isolating features.
Plate Set Part Numbers:
400124 (400 Series)
120102 (1200 Series)
160110 (1600 Series)
