Hardy's HI 5500 series signal conditioners are DIN-rail mountable modules that provide a building-block approach to monitoring important machinery.

Vibration monitoring or rotating machinery has been practiced for many years in many industries and has proven to be a valuable approach to improving manufacturing operations. Some of the primary benefits are:

· Increased production time
· Increased product quality
· Improved safety in the production environment
· Reduced maintenance costs
· Reduced energy costs
· Reduced parts inventory

The HI 5500 Series modules may be used to monitor motors, pumps, fans, chillers, mixers, gears, compressors, machine tools, and practically any rotating machinery. These modules serve the petroleum, chemical, power, pulp/paper, food/beverage, metal fabrication, transportation, and a number of other industries.

The HI 5500 series of vibration signal conditioners are DIN rail mountable modules and provide a "building-block" approach to monitoring vibration on important machinery. Each signal conditioner has a 4-20 mA and 0-5Vdc output proportional to its full scale value. The outputs can be connected to most PLCs or DCS systems, providing continuous monitoring of machinery running condition.

The modules also provide access to the buffered vibration signal at a BNC connector and terminal connectors. Measurement type, detection type, frequency range and full scale operating range are selcted by the user.

Additionally, there are set point modules and relay modules that can be configured to light an annunciator or trip machinery when operating conditions exceed preset levels. The set point modules and relay modules can be used with a single signal conditioner or with groups of signal conditioners, providing a cost-effective approach to creating a monitoring system.
