Reciprocating Machinery Protector detects shock loads
The IMI Sensors division of PCB Piezotronics has launched the Model 649A01 Reciprocating Machinery Protector (RMP), which is claimed to utilise the next generation of impact monitoring technology.
This two-wire, loop-powered, 4-20mA transmitter detects impacts from mechanical shock events, which typically occur in or near a machine's cylinder assembly. This technology is particularly effective 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 of the RMP allow users to customise 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.
