Reciprocating Machinery Protector for Continuous Vibration Monitoring and Protection of Reciprocating Compressors
The IMI Sensors Division of PCB Piezotronics’ Model 649A01 Reciprocating Machinery Protector (RMP) uses next-generation impact monitoring technology. This two-wire, loop-powered, 4-20 mA transmitter detects impacts from mechanical shock events, which typically occur in or near a machine’s cylinder assembly. This technology is appropriate on reciprocating machinery where these high frequency impacts are often overlooked, or when trending overall vibration levels. The hermetically sealed design can be easily interfaced with existing alarm, control and monitoring systems such as PLCs, DCSs and SCADA systems. The field programmable features allow users to customize each installation point and tailor the output to suit their application. This includes variable set points and alarm levels for optimum performance. The RMP detects common reciprocating compressor faults such as loose or broken bolts, cracked connecting rods and scoring in the cylinder.
