Robertshaw's 4-20 ma Vibration Transmitters

Model 570B Loop-Powered Stud Mount Vibration 4-20ma Transmitter

Robertshaw Model 570B vibration transmitter Robertshaw's model 570B is a loop powered (12 - 36 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.

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.

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

Robertshaw Model 571A I.S. vibration transmitter 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. FM Approved Intrinsically Safe (with barrier) & Non-Incendive (without barrier).

Robertshaw Electronic Vibration Monitor Model 566

The Model 566 can provide 4-20ma output, alarm setpoints, measure acceleration or velocity and is in an explosion proof enclosure

Robertshaw Model 566 Robertshaw Model 566The Robertshaw Model 566 Vibration Monitor is a solid state instrument that encompasses a variety of functions all in one unit. Vibration can be monitored in either velocity or acceleration. The standard ranges are 0 to 1.5 inches/second or 0 to 3 inches/second when sensing velocity and 0 to 5 g's or 0 to 10 g's when sensing acceleration. A 4-20 mA DC output is provided to drive a 750 ohm maximum load. The Model 566 includes two solid state Triacs (2 amp @ 120/240 VAC) which can be operated in a N.O. or N.C. configuration. Alarms are capable of being latched or non latched (ON-OFF). Alarm # 1 has a monitor time delay adjustable from 0.5 to 15 seconds. LED setpoint indicators are provided to indicate the alarm condition. The Model 566 vibration instrument and optional remote mounted sensor are housed in a weatherproof and explosion proof enclosure. NOTE that on the remote sensor unit the connection from the Model 566 to the remote sensor need only be an ungrounded pair of twisted wire.
