Model 571A Vibration Transmitter - Intrinsically Safe, Loop-Powered, Stud Mounted

Robertshaw’s model 571A is a loop powered (14 – 32 VDC) vibration transmitter that provides a 4-20 mADC output proportionate to vibration. The transmitter is available with a variety of acceleration and velocity ranges. This rugged (316L Stainless Steel, NEMA 4X, IP68) compact unit provides continuous monitoring of machine vibration for trending, alarm and/or shutdown when used with a PLC, computer, DCS, data logger or current relays. When used with an approved barrier the transmitter is intrinsically safe for use in hazardous locations. Without a barrier the transmitter is rated non-incendive.

Installation is simple and no calibration is required. A 1/4-28 tapped hole and a 1/4-28 stud is provided for mounting. The unit has a 2 pin connector and mates with a standard MIL-C-5015 2 socket connector with splashproof boot for a weatherproof, splash-proof connection. Optional cable assemblies are available in lengths of 16, 32, 64 and 112 feet.
