AMTS Monitoring Rail Clip Prisms
Advantages
Easy Installation: Position rail clip and tighten screws. No drilling or wiring required.
Durable: Simple, waterproof construction with no moving parts or electronics.
High Performance: Coated optics for better performance.
Cost Effective: Low cost per monitored point compared to conventional sensors.
Installation
Rail clip prisms are typically installed on both rails and spaced along the track at specified intervals. A single AMTS can monitor rail clip prisms up to 600 feet away, assuming good angles of view and clear line of sight.
- Fit the rail clip to the rail. Tighten the hex screws until the clip is firmly attached.
- Attach the L-bar, adjusting its angle so that the prism will directly face the AMTS.
- Attach the prism to the L-bar, aiming it at the AMTS.
