The 3500 Series is our premier offering in a traditional rack-based machinery protection system and is designed to meet the needs of the majority of our customers. Monitor modules exist for a very wide range of measurements, and the system is designed to meet the requirements of American Petroleum Institute Standard 670 and is available with TUV certification and reliability data when specific Safety Integrity Levels must be met. It is our most flexible system with the ability to operate with or without displays, software-configurable monitor modules, and varying levels of redundancy including dual power supplies and Triple Modular Redundant (TMR) monitor configurations for even the most demanding applications. The system is also available with optional high-speed data capture capabilities when connection to our System 1TM condition monitoring software is desired. These capabilities are completely internal to the 3500 rack, require no additional rack space, and do not interfere with basic machinery protection functions.
