The Model HI 5703ST operates off the power supplied by most DCS systems. Its ability to operate right off the loop makes installation simple and straightforward. Simply mount the unit on the machine case, and connect its two wires into a 4-20 mA current loop.
Experience has shown that damage will be minimized if the conditions
causing the machine stress are quickly corrected. The HI 5703ST has been designed and developed to remain perched on the bearing cap, transmitting the machine stress energy levels into the 4-20 mA loop.
On-line monitoring of critical equipment is a reality when the HI 5703ST is wired to a process
computer. Pattern recognition provides additional rewards if the stress energy level is stored for historical trends.
The HI 5703ST listens for the high frequency emissions of a machine in stress. Pumps generate this stress energy emission when they cavitate, run dry, become excessively loaded, or develop impending bearing failure.
Other sources of stress energy emissions are gear problems, seal and bearing rub (sleeve or pad bearings) and high pressure leaks.
