Avoid Catastrophic Failure 

 
Protect your rotating or reciprocating 
machinery, including pumps, motors, fans, 
blowers, gear boxes, compressors, turbines 
and other machinery from excessive vibration.  
Vibration monitoring will alert you of 
increasing machine vibration levels so 
preventative maintenance can be scheduled 
before catastrophic failures occur. 
 
 

General Description

 

 
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 splash-
proof boot for a weatherproof, splash-proof 
connection.  Optional cable assemblies are 
available in lengths of 16, 32, 64 and 112 feet.
