ST5491E Indicating Velocity 4-20 mA SEISMIC PRODUCTS Vibration Transmitter Applications • • • • • • • • • • Blowers Centrifuges Compressors Engines Fans Generators Motors Pumps Turbines Turbochargers Model ST5491E is the ideal solution for sensing vibration on most plant equipment. This precision case mounted, indicating velocity vibration sensor and signal conditioner in a single package is built to provide years of reliable service. A simple two-wire loop signal proportional to velocity is generated for transfer to a programmable logic controller (PLC), distributed control system (DCS) or other 4-20 mA input devices. Simply mount the transmitter on the machine case, connect the 2-wire loop and read and/or record the vibration.
