AMS 6300 SIS Digital Overspeed Protection
AMS 6300 SIS Digital Overspeed Protection
Overspeed conditions on critical rotating equipment can be damaging to your assets and the plant personnel in the area.
In addition, damaged equipment is expensive and time-consuming to repair or replace. During transient and normal operation, the AMS 6300 SIS guards against overspeed conditions caused by sudden load loss and unexpected changes. In addition, the same sensors will verify the rotational direction of your rotating equipment to ensure your assets are functioning correctly.
