Maryville, Tenn. - Model 571 is an intrinsically safe loop-powered stud-mounted vibration transmitter. The device is used to protect rotating and reciprocating machinery from catastrophic failure by alerting personnel to increasing vibration levels. The Model 571 measures both acceleration and velocity in three ranges and is reverse polarity protected. The loop-powered sensor provides a 4-20 mA dc output proportionate to vibration and offers continuous monitoring of machine vibration for predictive maintenance trending, alarm, and shutdown when used in conjunction with a PLC, computer , DCS, data logger, or current relays. Said to be easy to install, the 571 features a 1/4-28 tapped hole and stud for mounting and requires no transportation. Its sensor is corrosion resistant, NEMA 4X rated, and EMI protected.
